Abstract
Integration of a large capacity of wind generation in the Great Britain
(GB)
electricity
network is expected to pose a number of operational challenges. The variable nature of wind generation
necessitates introduction of technologies that can provid
e flexibility to generation portfolios and
therefore compensate for intermittency of wind generation. In this paper, the efficacy of three options
to address electricity balancing challenges was evaluated: flexible gas
-
fired plants, electricity storage
and
Power
-
to
-
Gas system. The combined gas and electricity network model (CGEN) was enhanced and
th
rough adopting a rolling optimis
ation approach the model aims at minimi
s
ing the operational cost of
an integrated gas and electricity networks that represents a
GB
system in 2030. The potential impacts
of employing each of the flexibility options on the operation of the integrate
d electricity and gas
networks we
re investigated
.
The analysis showed that
amongst all the flexibility options,
the
deployment of grid
-
sc
ale electricity storage will
achieve the highest reduction in the operational cost
of the integrated system (
£12 million
reduction
in
a typical winter week, and
£3 million
reduction
in
a
typical
summer
week)
.
The results of this study provide insights on the system
-
wide benefits offered
by each of the flexibility options and role of
the
gas network in the energy system with large capacity
of wind generation.
