Abstract
As the share of variable generation in power systems
increases, there is increasing value in more flexible use
and generation of electricity. The paper compares the
economic value of several flexibility options in a large
power system with a large amount of reservoir hydro
power. Generation planning models are needed to consider
the impact of flexibility options on other investments in
a power system. However, generation planning models do
not include all the relevant operational details. The
approach in the paper combines a generation planning
model with a unit commitment and dispatch model. The
results demonstrate the value of coupling the heat and
power sectors and the value of transmission. Low-cost
electricity storage does not appear to be as decisive in
the Northern European context with wind power as the main
variable generation source. The paper also addresses
methodological issues related to the inclusion of
operational constraints in generation planning.
