An assessment for technical, economic, and environmental challenges
facing renewable energy strategy in Egypt
Key Words:
Assessment, Technical, Economic, Environmental Challenges, Renewable Energy, Strategy, Egypt.
Summary:
Securing energy demand for next generations is one of the most challenges aspects facing any sustained
development plans, due to the growing electric energy demand and Egypt as a country of limited fossil
fuel resources has to diversify its energy portfolio by utilization of its renewable energy resources,
mainly wind due to its economic potential and solar as proved by Egypt's wind and solar atlases. In the
year 2009/2010 the total installed capacity in Egypt was 24726 MW with electricity generation 139,000
GWh, of which 89% was delivered by thermal plants and about 10% from Hydro power with total
installed 2800 MW and electricity generated is about 12863 GWh and 1% from Wind energy with total
installed 550 MW and electricity generated 1542 GWh. In the solar energy field, the first solar thermal
power plant of 140 MW with a solar share of 20 MW using parabolic trough technology with estimated
total energy generated of 852GWh/year.
Recently, Egypt has adopted an ambitious plan to cover 20% of the generated electricity by renewable
energy by 2020, including a 12% contribution from wind energy, translating more than 7200 MW gridconnected wind farms. Such plan gives a room enough to the private investment to play the major role
in realizing this goal.
Due to the high investment cost of solar energy technologies, still limited in spread all over the world
on the other hand wind energy has an economic potential and becomes a commercial technology but the
future potential for solar energy due to the limited land for wind energy.
The current study evaluate the Egyptian strategy for renewable energy up to 2020 and find how much
the planned projects from the Egyptian government will fulfill its target, the economic study and the
expected investment cost of these projects, and the environmental impacts of the renewable energy.

Analytical and comparative study for solar thermal cooling and
photovoltaic solar cooling in the MENA region
Key Words:
Renewable Energy, Solar Thermal Cooling, Photovoltaic Solar Cooling, MENA Region
Summary:
In this thesis, a comparison and analyses of solar thermal and solar photovoltaic (PV) airconditioning technologies for a Typical Single Family House (TSFH) in two different MENA
climates, Aswan-Egypt and Aqaba-Jordan, are performed, Three scenarios are designed in order to
compensate the TSFH’s annual cooling demand in each selected climate. These scenarios are solar
thermal air-conditioning with storage (absorption chiller), PV air-conditioning without storage and
PV air-conditioning with storage.. The PV air-conditioning scenario with storage behaves and
compensates the cooling demand better than the solar thermal air-conditioning with storage
scenario and needs less storage to cover the same amount of cooling load demand. However, the
storage system in the PV air-conditioning scenario is minor and the direct compensation is major..

The potential of Fresnel reflectors for process heat generation in the
MENA region
Key Words:
Renewable Energy, Fresnel Reflectors, Process Heat Generation, MENA
Summary:
This study assesses the potential of generating solar heat for industrial processes with linear Fresnel
collectors in the Middle East and North Africa to be around 460 TWh. Based on a comprehensive
top-down approach Morocco and Tunisia are identified as most promising. Within the bottom-up
approach 10 companies in Morocco and 7 companies in Tunisia were visited and their potential
assessed in more detail. Moreover, the most promising industries were examined on potential
benefits and challenges. Furthermore, the major legislations and institutions of the countries are
included in the assessment. A single variable sensitivity analysis examines the factors which
influence the internal rate of return and thermal energy costs of solar process heat systems. A
reference scenario shows that currently solar process heat systems with linear Fresnel collectors are
not feasible in Morocco or Tunisia. An institutional comparison identifies most suitable support
schemes for solar process heat systems. Based on the results the study provides recommendations
for policy makers and the private sector.

The Moroccan solar plan - a comparative analysis of CSP and PV
utilization until 2020
Key Words:
Renewable Energy, Moroccan Solar Plan, CSP, PV
Summary:
The present master thesis provides a database of performance indicators such as energy yields,
capacity factors, typical efficiencies and losses of technical components, LCOE, and difference
costs (DC: LCOE minus avoided costs of the conventional power system) for fixed tilted, 1-axis
horizontal, 1-axis vertical and 2-axis tracking PV and CSP with no, 6, 12 and 18 full load hours of
thermal storage. HelioClim irradiation data of 2005 for the sites in Ouarzazate, Ain Ben Mathar,
Boujdour, Laayoune and Tarfaya is used ranging between 1,927 - 2,428 kWh/m2/y (DNI) and
1,968 - 2,154 kWh/m2/y (GHI).
An extensive sensitivity analysis for WACC and price escalation of conventional energy shows that
for only PV and only CSP scenarios in 55 and 22 out of 72 cases the DC are negative - although no
environmental costs for conventional generation are internalized. The weighted average extra costs
of a feed-in tariff for the analyzed scenarios range between 0.4% - 8.1% of today´s electricity price
until break-even with conventional energy.

Potential in systematically placing a high capacity of PV and wind
sources in Germany storage and transmission capacity requirements
analysis and a case study on Morocco
Key Words:
Renewable Energy, PV, Wind, Germany, Morocco
Summary:
This MATLAB-based technical study analyzes the potential of a systematic-optimized placement
of wind turbines and Photovoltaic panels (PV) to minimize the requirements for the energy supply
structure by reducing the residual load in Germany. A simpler case study is also presented for
Morocco. This study seeks to analyze the installed capacity required to ensure that PV panels and
wind turbines contribute to reduce significantly the residual load in Germany based on the
allocation methods used in this study. In addition, Germany was divided into six regions to see the
impacts of optimizing the installation of PV and wind capacity in small regions to the whole
system, allowing us to take into consideration transport and storage capacity requirements needed
to consistently fulfill the maximum load demand. These results for storage capacity requirements
and transport were compared to two scenarios: Germany as one region scenario and another
reference scenario, and results showed that maximum transport capacity needed is 27% and 12%
less than the two scenarios respectively and capacity storage requirements are 13% and 2% less
respectively. The case study on Morocco provides a theoretical estimation of the installed PV and
wind capacity required to fully cover the yearly energy consumption and was found to be 19,520
MW and 12,250 MW for PV and wind respectively.

Title of Thesis:
Dynamic simulation of a PV-diesel-battery hybrid plant for off grid
electricity supply.
Key Words:
Renewable Energy, PV, Diesel, Hybrid Plant, Off Grid Electricity
Summary:
This thesis analyzes different control strategies to improve the operation of stand-alone PV-diesel
generator-battery plants, and to reduce the operation cost accordingly. Therefore, four control
strategies are proposed according to primary and secondary control of frequency. Each control
strategy provides different loading patterns of the diesel generators and the storage system.
Dynamic simulations of the plant operation are performed according to each control strategy. The
simulation results show that the control strategy, which covers the power fluctuations mainly from
the battery system, demonstrates more constant output power of diesel generators, lower frequency
deviations, less fuel consumption, better performance of the diesel generators and less cost of
energy, but less expected lifetime of the batteries compared to the other analyzed control strategies.
On the other hand, the control strategy, which covers the power fluctuations from the diesel
generators and the battery system in parallel, demonstrates higher variation in output power of the
diesel generators, higher frequency deviations, higher fuel consumption, less favorable
performance of the diesel generators and higher cost of energy, but higher expected lifetime of the
battery compared to the other analyzed control strategies.

Energy efficient management and optimization strategies in office
buildings by implementing simulation-based optimization control
Key Words:
Energy Efficiency, Office Buildings, Simulation-Based Optimization
Summary:
This research presents a framework for using simulation-based optimization control approach in
reducing primary energy consumption from a HVAC system in a Bosch office building in
Schwieberdingen near Stuttgart, Germany. Two systems supplying heating energy to the building
are investigated; the installed ventilation system and the static irradiative heating system. A
building model is created using TRNSYS and calibrated to meet a satisfying agreement with the
real building behavior. This model is used for fault detection and new control configuration
investigations. However, the control parameters that influence the primary energy consumption are
identified using a sensitivity analysis. Accordingly, it is found that the supply air temperature, the
air volume flow rate, and energy required to heat coils are the main parameters that should be
controlled to reduce the primary energy consumption. Two optimization control approaches were
conducted in this research. The 1st optimization method is applied using TRNSYS (a forward
model) whereas the 2nd optimization method is applied using linear optimization with LINPROG
algorithm in MATLAB (a data-driven model). The results show that 24% of primary energy
savings is achieved by using appropriate control strategy.

Potential of local manufacturing for wind and CSP components in
Egypt.
Key Words:
Renewable Energy, Local Manufacturing, Wind, CSP, Egypt
Summary:
This work reflects the current Egyptian energy market situation and focuses on assessing the
existing possibilities regarding local manufacturing potential for wind and CSP technologies.
Combined with conducted interviews this thesis presents the status quo and possible outlook of the
renewable energy industry in Egypt. Based on conducted interviews in addition to a workshop, this
thesis evaluates the future possible local share of component manufacturing for wind and CSP
technologies and analyzes different scenarios regarding the deployment of these two technologies.
This analysis produced a number of key findings; the survey shows that the technical potential for
domestic production for the two technologies is promising. However, the uncertainty of a long term
renewable energy strategy for the country and the highly subsidized fossil fuels combined with a
lack of communication between the key players present a significant obstacle for a growing
renewable energy market. A multi-pronged approach is essential to overcome the barriers and to
accelerate the development of the local manufacturing industry for wind and CSP technologies.
This approach considers political, regulatory, technical as well as financial measures. The main
outcome of the scenario analysis shows that a combined CSP and wind energy scenario can lead to
an improved renewable energy market development and extensive local manufacturing possibilities
which can benefit Egypt in a socio-economically, economically and ecologically. This combined
approach has a more positive effect on the country than a strongly wind energy biased path.

Modeling and performance analysis of a hybrid biogas-photovoltaic
system
Key Words:
Renewable Energy, hybrid, biogas, photovoltaic, Eichhof center, Germany, Jordan
Summary:
The integration of PV and biogas with a focus on biogas as a flexible electricity supplier is
thoroughly investigated in this thesis. The performance of the biogas/PV hybrid system at Eichhof
agricultural center in Germany is evaluated. The complete electrical and thermal energy system is
analyzed and modeled using Simulink. A proposed future scenario for a more sustainable, reliable
and autonomous system is developed. Finally, a case study to determine the feasibility of this type
of hybrid systems on a dairy farm in Jordan is carried on.
Finally, it was concluded that in order to ensure the feasibility of a similar hybrid system in Jordan
the tariff at which the produced electricity is sold to the utility grid should be more than 0.02
JD/kWh (0.021 €/kWh) for a large size project (1.65 MW installed capacity) and more than 0.03
JD/kWh (0.032 €/kWh) for the smaller project (0.22 MW installed capacity). The large scale
system proved to be generally more feasible and had a levelized cost of electricity of 0.136 JD/kWh
(0.146 €/kWh). The project has a total investment of 5.4 million JD (5.78 million €).

Design, simulation, and emulation of a residential load management
algorithm utilizing a proposed smart grid environment for the MENA
region
Key Words:
Energy Efficiency, Residential Load Management, Smart Grid, MENA
Summary:
Demand side management strategies have been used by the industry for many years for managing
mainly large and predictable loads. Supply constraints – caused principally by capital intensive
costs and geopolitical challenges of building new generation capacities – are convincing utilities to
take a new look at the hefty role demand side management can play in controlling the consumption
of smaller commercial and residential customers
The objective of this thesis is to shed light on the current electric energy situation and practiced
demand side management activities in countries of the MENA Region. It also aims at
recommending suitable communication and control technologies for a proposed regional smart grid
environment. In addition, in this thesis we develop a load management algorithm which reduces
peak electricity consumption in residential units and manages the operation of household
appliances according to utility controls and consumers preferences; thus creating efficient resources
allocation at consumer premises and consequently improving the load factor of associated
generation capacities. Furthermore, we propose some modifications to existing electricity billing
schemes to promote more rational electricity consumption patterns.

Performance simulation for parabolic trough concentrating solar
power plants and export scenario analysis for north Africa
Key Words:
Renewable Energy, Parabolic Trough Concentrating, North Africa
Summary:
The thesis is providing a model witch can calculate the electrical output of CSP parabolic trough
plants for several locations in North Africa. Furthermore it is analyzed how these CSP plants can
contribute to a 100% renewable energy supply in Germany for the year 2050. Therefore the first
part of this thesis presents a model estimating suitable locations for CSP plants in North Africa and
calculating the electrical output of CSP plants. Several criteria’s for land use, annual irradiation and
infrastructure, are processed, and rules for depositing CSP plants were specified. In alliance with
weather prediction models an energy-balanced CSP model simulates the electrical output of
exclusive solar driven CSP parabolic trough plants. By using different configurations the
simulation can display various forms of storage sizes and different cooling system.
Therefore, the effective load carrying capacity (ELCC) and the capacity credit (CC) for a number
of CSP plants in relation to the residual load in Germany is evaluated. The focus is on the influence
different storage sizes have on the possibility to supply energy on demand for Germany. The work
shows that even a high capacity credit of around 53% for solar multiple four CSP plants is not
necessarily helpful to reduce significant the high demand in Germany during winter times.

Analysis and evaluation tools development of photovoltaic modules and
system performance under Jordanian and German climatic conditions
Key Words:
Renewable Energy, Photovoltaic, System Performance, Jordanian, German
Summary:
The aim is to develop an evaluation tool for analyzing the performance of the different photovoltaic
technologies. This thesis was performed for two sites, Kassel in Germany and Ma’an in Jordan.
For the Kassel site, a comparison between two different irradiation measurement sensors
(Pyranometer and ISET sensor) was performed, then an estimation of electrical and thermal
characteristics for the two photovoltaic technologies (polycrystalline Silicon and micromorphous
silicon μ-Si) has been investigated by the simulation model. Moreover, the outputs of the simulation
were evaluated by using a real measured data for the module and system level. The evaluation of
the output power for the module and system levels show less deviation by using ISET senor as the
base of irradiation measurement, while it was deviated more when measuring the irradiation via
pyranometer. Therefore ISET sensor was more accurate than pyranometer for irradiation
measurement. For the Ma’an site, estimation of electrical and thermal characteristics for the two
photovoltaic technologies (polycrystalline Silicon and Cadmium Telluride CdTe) has been
determined by the simulation model. The estimated output power shows that the highest energy
yield was occurred at the optimum tilt angle (32o). Generally, in the both sites the results show that,
thin film technology achieves a higher specific energy yield than polycrystalline technology.

Wind farm design and a comparative assessment of selected regions in
Jordan
Key Words:
Renewable Energy, Wind Farm, Jordan
Summary:
Five sites were selected in different regions of Jordan (north-Hofa, north-Ibrahimya, middle-Tafila,
middle-Fujaij, and south-Aqaba). Measurements by the National Energy Research Centre (NERC)
where collected for many years, these measurements were evaluated in order to have an overview
about the potential of wind resources in Jordan and to compare the different potentials for these
sites. Those measurements were raw data of the average wind speed and wind direction
. A wind farm was designed in each of the selected site by using the Wind PRO software and then
technical and financial assessments were carried out. Those assessments have proved that the wind
energy project can be a successfully project in Jordan and they are very attractive to investors. The
Aqaba wind farm has shown that it is the best when compared with the other selected sites while
the Tafila wind farm is in second place. Those two sites are likely the most promising sites to
continue achieving the target of supplying Jordan with cheap and reliable energy. Also, they
compensate each other depending on the season. Moreover, the two scenarios are suggested to
achieve the Jordanian target 1000MW of wind energy by 2020 according to this thesis’ results.

Technical and economic performance of parabolic trough in Jordan
Key Words:
Renewable Energy, Parabolic Trough, Jordan
Summary:
The aim of this study was to investigate the technical and economic aspects of parabolic trough
performance in Jordan. The technical aspect was addressed by developing an empirical
mathematical model for the performance of a parabolic trough demonstration plant installed in the
Dead Sea area.
Photogremmetric test was conduct on the parabolic trough collector to determine the optical
quality. The total optical error was evaluated to be 20.6 mrad which resulted in an intercept factor
at normal incidence of 0.72. The empirical parameters of the overall performance model were
determined by applying the multiple linear regression (MLR) tool on a series of measurements for
the system performance. The developed model suggests that the optical losses in the system are
much higher than thermal. Where at normal incidence (peak optical efficiency) and a mean heat
transfer temperature of 80oC, the system losses were modeled to be 47% optical and 11% thermal.
The LCOE for the proposed parabolic trough plant in Ma’an was estimated to be 20.96 ¢/kWh for a
base-case scenario and 17.89 ¢/kWh for an incentive scenario (tax exemptions) which is still high
compared to the current cost of electricity using fossil fuel in Jordan (9.64 ¢/kWh). Sensitivity
analysis revealed that th

Design and characterization of a small wind turbine model equipped
with a pitching system
Key Words:
Renewable Energy, Small Wind Turbine, Pitching System
Summary:
A small pitch-controlled wind turbine with a 0.58 m rotor diameter has been designed, constructed
and tested in the wind tunnel. The blade is a prototype of a larger blade that has been constructed in
an earlier project. This thesis dissertation covers two main tasks. First, careful characterization of
the small wind turbine is carried out at different wind velocities and pitch setting angles. Second, a
pitch control system is implemented to control the power output of the turbine at wind speeds
above the rated speed. Two control strategies have been adopted for this model; load control below
the rated wind speed, and pitch to feather control above the rated wind speed.
A novel lead screw mechanism is implemented for controlling the pitch angle by a stepper motor.
This proved to be efficient and convenient for small wind turbines and worked perfectly. All
measurements and control actions were achieved by utilizing a National Instruments data
acquisition cards and a custom developed LabVIEW program. The wind tunnel measurements of
the wind turbine characteristics were not as expected. The wind turbine maximum power
coefficient was of the order of 0.02 and optimum tip speed ratio was around 3.2 at the rated wind
speed of 9 m/s.

order to investigate the effect of this control strategy on wind turbines by characterizing its design
and output power.
The small wind turbine model components were mentioned with specifications and functions in
addition to description of the Lab View program.
The model was experimented in the wind tunnel exists in Oldenburg University where a testing
procedure was followed. The procedure included the way how to measure the output voltages and
currents from the generator at different wind speeds and how wiring should be connected.
This fruitful work resulted in drawing the power and c– λ curves. Discussions of the obtained
results were made and several factors were listed. These factors, such as friction, affected the
model’s performance. These discoveries helped in proposing useful modifications for the system in
order to enhance it.

Summary:
A quantitative, objective, and analytically index that describes the competence of renewable energy
market of world countries is derived. The proposed index, Renewable Energy Market Competence
Index, is composed of 13 general indicators and 5 technology dependent indicators. The index
structure allows including more indicators for more accurate representation of the relative
competence among the countries. Though the index calculation depends on weighted average
between the average of the 13 general indicators and the average of 3 of the technology dependent
indicators, applying the index on Concentrated Solar Power (CSP) technology for 18 countries
shows very minor change of the index results (score and rank) with the change of the weighting
parameter. This is due to the high correlation of the general indicators and the three technology
indicators values, suggesting that even a simpler version of the index that is composed only of 5
technology indicators is sufficient to give a very good measure of the relative competence among
the countries.
A comparison of the proposed index with CSP Countries Attractiveness Index, that is developed by
Ernst & Young Inc., shows a very good matching (correlation >85%) between both score and rank
of the two indices for the 11 common countries. Despite of the relatively large difference in score
between the two indices (17 to 22 points) for 3 countries (South Africa, Greece, and Tunisia), the
difference in the remaining 8 countries does not exceed 7 points.

Optimal mix analyses of renewable power generation in the MENA
region
a case study for Morocco
Key Words:
Renewable energy, MENA region, Optimal mix of renewables, Morocco, Renewable power supply
systems
Summary:
The reduction of greenhouse gas emissions and pollutants as well as security of supply is
considered as the main driving forces for the transformation of current power supply systems to
modern systems based on Renewable Energy Technologies. The MENA region, compared to other
regions in the world, is a unique place for harnessing renewable energies. The world’s highest
potential of renewable power generation is located in the MENA region, as 45 % of the world’s
potential for solar energy is concentrated there. It has also a strong potential of wind energy.
Taking the approach of “let the weather decide” into account, which means that the fluctuated
weather-driven renewable energies are combined according to the weather circumstances, this
study aims to find the optimal mix of renewable power generation in Morocco for three different
scenarios by 2020

Key Words:
Decision Support Tool, Self-Consumption, PV, Storage, Battery, Thermal Energy Storage, Cost Of
Energy, CO2 Emissions, Feed In Tariff.
Summary:
In this research, a decision support tool has been developed in Matlab to help the facility managers
to decide which sizes of PV system, electrical and thermal energy storage they need to install in
order to achieve the optimum self-consumption, technically as well as economically.
The American University of Cairo “AUC” has been chosen as a case study for this research. Hourly
load estimation of electrical and thermal loads has been simulated under the weather conditions of
Cairo.
Increasing the PV system, increases the self-consumption of the facility and decreases the net
present value and the return on investment at low electricity prices and no feed in tariff. Increasing
the feed in tariff values leads for increasing the net present value and return on investment. On the
other hand, it has been noticed that, using batteries as a storage system is economically infeasible
when there is feed in tariff.

efficiency.
Key Words:
Alternator Management System (AMS); Central Energy Management (CEM); Energy Conversion;
Energy Efficiency; Software Development.
Summary:
Rising energy prices, declining availability of primary energy, increased environmental impact and
commitment to the sustainable development for future generations are now a days the prime
movers for the governments around the world to have the best possible energy efficient
technologies employed in their countries in order to meet global environmental standards and
requirements which seem to be becoming strict more and more.
In the field of commercial vehicles, the conventional internal combustion engine due to its
performance and weight cannot be replaced in the near future by the hybrid technology. However,
there is a potential for reducing fuel consumption through a new software is being developed that
controls the alternator to improve the energy conversion efficiency. This software called
“Alternator Management System (AMS)” was tested in the federal Republic of Germany and the
Hashemite Kingdom of Jordan by carrying out representative test drives. The results shows that
having the AMS installed in a vehicle could reduce the fuel consumption in the range between 0.29
and up to 0.72 % of the overall engine consumption. In addition, it is possible to reach a CO2
saving of 900 kg CO2 per year per truck. The best results could be obtained in the city application.
Nevertheless, results comparison proves the possibility of applying the new system in different
market other than Germany.

Summary:
The main purpose of the study is to simulates the effect of the battery temperature on the different
battery parameters and develop battery model that simulates the real reactions happens inside the
battery then integrate this model with different grids with different power sources. The Simple
Model did not consider the temperature change in its equivalent circuit and it depends on many
assumptions such as the relation between the voltage and state of charge is assumed to be linear and
it is not like that. Ceraolo Model considered the temperature change in the battery and its effect in
the battery parameters. Ceraolo Model was integrated to the BESS instead of simple model and
many adjustments are done to the BESS model to run it in Power Factory DigSIlENT as it is a
common grid analysis tool in the area of distribution of renewable energy sources and power
systems.

Summary:
Studies show that the electricity demand in the MEAN region is significantly increasing therefore
the interest in renewable energy is growing very fast. Renewable energy is the future of MENA
region because it has a great potential, especially wind energy. Though wind energy has great
advantages, it has also some disadvantages. These disadvantages can be avoided by using offshore
wind energy. The most important part in offshore wind turbine structure is the foundation as it is
constructed in water. The present master thesis focuses in finite element modeling and analysis of
(grouted connection). A calibration of the material used in the simulation has been carried out
assuring an accurate model of the used material by ATENA program. The research is concluded
with a result that the calibration showing a good agreement between the ATENA program material
behaviors and the experimental results. After the calibration has been done, the modeling of the
typical grouted connection with shear keys is analyzed by finite element analysis program (ATENA
program). The stresses were studied in short and long struts for the model with shear keys.
Comparisons were also made without the use of shear keys to better understand the effectiveness of
the shear keys. The results show that the model will be not fail under the case loading. Although
the shear keys can deteriorate and become weak due to the stress concentrations around the shear
keys, it is recommended to use shear keys because it help to distribute the stresses along the grout

Buffer; Diesel-Powered Cooling; Fuel Subsidy Removal; Egypt
Summary:
An off grid solar PV-driven system for precooling and storing post-harvest crops is proposed for
desert agricultural areas in Egypt. For operation during night as well as days with low solar
radiation, both thermal and electrical energy storage is considered. Previously existing parametric
MS Excel-based models are further developed and integrated into a new model to simulate the
system hourly operation throughout the year. The weather data, cold store construction, stored
crops properties, and a crops loading/unloading scenario are inputted to the developed model. The
cooling load time series is accordingly calculated. Based on the parameters of the inputted system
components the operation is simulated and the technical feasibility is assessed. As an example, a
case is considered where a 20ft-reefer container is used as cold store and tomatoes are loaded and
unloaded in a certain scenario. The model compares different alternatives resulting from trades of
components sizing. The most economical alternative is compared to a conventional diesel-powered
reference system with different scenarios of gradual removal of subsidy of diesel in Egypt.
