Smart grids
Stockholm Royal Seaport – a world-class,
sustainable city district
The grid of the future is being built here
Today, 50 percent of the world’s population lives in cities
and that figure is expected to rise to 70 percent by 2050.
This puts enormous demands on entirely new energy
systems that can cope with such growth and still achieve
high environmental goals. This is also what’s behind the
considerable international interest in the Stockholm Royal
Seaport project. The City of Stockholm is building a worldclass environmentally friendly city district at this location,
using smart energy technology from ABB. This city district
is also one of the projects supported by the Clinton Climate
Initiative Program. Some of the climate and environmental
goals for the project are for to become climate positive
and fossil-fuel-free by 2030. At the same time, carbon
emissions should be less than 1.5 tons per person. Today,
the average level in Stockholm is 4.5 tons per person.
Stockholm Royal Seaport stretches from Husarviken Bay in
the north to Loudden in the south. It also includes the ports,
Värtahamnen and Frihamnen. Furthermore, this district is
one of Europe’s most extensive city development projects.
The first homes will be ready for occupancy in 2012 and it is
expected that construction on the entire area will be completed
by 2030. Stockholm Royal Seaport will offer 10 000 residential
units and 30 000 offices, as well as a new port facility.
At this site, ABB is working with the utility company, Fortum,
and other stakeholders to develop new solutions for the smart
grid of the future.
Among others, residents of Stockholm Royal Seaport
will be able to:
– Produce their own electricity from solar panels installed
on the rooftops. The smart grid also makes it possible to store electricity in local storage units, or feed it back into the grid – for either own consumption or sale. The goal is for the properties to produce 30 percent of their electricity locally using solar power, wind power or by utilizing surplus energy in various ways.
– Influence how they use electricity and adapt their energy consumption (e.g. use of washing machines and dishwashers) to times of day when there is an ample supply of less
expensive, green electricity.
– Charge electric cars at their own charging stations. The smart
grid adapts charging to periods during the day when the price
of electricity is low and there is low environmental impact. Furthermore, with ABB technology, it could be possible in the future for electric car batteries to provide an effective
power reserve for the city district in the same manner as permanent energy storage units.
A smart grid used by active electricity consumers
A smart grid relies on intelligent energy technology, incentive
models and active consumers. This is why the technology and
market solutions that are presented focus on customer benefits
and continuously providing the right type of support to residents.
At Stockholm Royal Seaport, both new technology and a new
electricity market are being developed.
The Stockholm Royal Seaport project was launched in 2010
and during spring 2011, a proposal was presented for continued
efforts in the form of a pilot study. The next phase is now getting
underway. It involves installing and integrating the smart grid
with the residential and office facilities.
The project is sectioned into the following six work packages
and ABB is involved in each one:
This has to do with reducing energy consumption when the
price of electricity is high and shifting it to times during the day
when the price is low and there is less environmental impact.
The adaptability and flexibility provided by the smart grid,
along with new business models, will make it easy to do the
right thing. Residents will get immediate feedback showing
them that wise environmental choices are also profitable.
Active houses
The goal here is to achieve higher energy efficiency while reducing
peak loads by visualizing energy consumption and making it
easier for residents to become ”prosumers”, i.e. both active
electricity consumer and producers. For example, this involves
systems that automatically help start the washing machine
or charge an electric car when the supply of electricity is high.
ABB technology for Stockholm Royal Seaport
ABB already offers many solutions for smarter grids and
through its cooperation with others, such as utility companies,
Fortum, new opportunities are becoming available for converting
ideas into practical applications. At Stockholm Royal Seaport,
it is expected that technology and systems from many different
ABB units will be developed, integrated and combined.
Example of components are:
– Electricity generation using solar cells.
– Local energy storage.
– Control systems that enable a more efficient distribution
of energy consumption.
– Individual measurement and consumption visualization equipment for control, follow-up and metering.
– Stations for charging electric vehicles.
The development of Stockholm Royal Seaport is focused on such things as energy consumption, environmentally efficient transportation,
adaptation to climate change, recycling and lifestyle issues.

Significant resources are being invested worldwide to develop new, smart grids. ABB has extensive expertise in this area, which is why we have taken
an active role in the development.
The Smart Grid Lab
A complete operating environment will be created for full-scale
testing of smart grid applications based on ABB’s Network
Manager SCADA/DMS.
Example of components are:
– Technology for connecting ships to the local grid.
– Frequency converters for 50Hz/60Hz.
– Energy storage.
– Smart meters.
Example of components are:
– SCADA/DMS – smart grid applications.
– Control systems for optimal load control.
– Advanced business intelligence systems and electricity
market applications.
Stockholm Royal Seaport information management system
The information management system will be used to follow
up on the project’s goals. It will also provide data that can be
used for future research.
Grid development
This involves research on new grid design, which, among
others, reduces losses and improves the grid’s power quality.
Here are examples of tasks involved in the development effort:
– Defining relevant indicators for monitoring climate impact.
– Establishing a follow-up model for Stockholm Royal Seaport.
Example of components are:
– Medium and low voltage switchgear, as well as transformer
stations with extensive monitoring and control.
– Cable cabinets with control and monitoring.
– Centralized energy storage.
– Integration of charging stations for electric cars.
Market concept
This involves, among others, creating a business model
and a set of rules and regulations that makes it possible for
consumers to get more involved in the energy market.
Connections for ships to the local grid
Development of a flexible, cost-effective solution that allows
ships in port to connect to the local grid, no matter what
frequency is used onboard.
Here are examples of tasks involved in the development effort:
– Identifying test scenarios and test hypotheses.
– Creating a market model that makes it easier for consumers to participate in the energy market.
– Creating a market model and a set of rules and regulations for network operation of the smart grid.
