TIM 155
Week 2 – energy systems:
concepts
System –
Related parts that work together.
An organized method or scheme.
the energy supply chain:
extraction, conversion, delivery,
and use
Energy systems have four overall
requirements:
- meet demand fluctuations,
- adapt to supply fluctuations,
- operate efficiently,
- abide by regulations.
Storage –
decouples energy supply and
energy demand, thereby giving
greater system flexibility,
essential for both technical and
economic reasons.
Energy Pathway:
Movement/transitions of energy
from the energy source to its enduse, with storage, transmission,
and distribution in between.
Energy Pathway:
may also comprise storagetransmission-distribution-storage,
or some other combination.
- examples?
Energy Pathway:
- lets us think of an integrated
system approach to energysupply operations
- life-cycle-based,
- benefit-cost analysis possible
Infrastructure is needed for each
of the energy pathways.
Different energy carriers need
different infrastructure.
- Examples?
Repeat slide…
the energy supply chain:
extraction, conversion, delivery,
and use
Why is any centralized planning
needed?
Why can’t markets take care of
all of the coordination needed to
operate energy pathways?
GEA reading - p. 1156 of
pdf/1138 of text –
paragraph on RHS starting
“Aging equipment…”
– Let’s discuss this paragraph
- Why planning is needed.
If centralized planning is needed,
then why have markets involved
at all?
Why not let the government
manage all of energy supply?
See GEA p. 1156 of pdf/1138 if
