Impact of wind curtailment and storage on the Irish power system 2020 renewable electricity targets: a free open-source electricity system balancing and market (ESBM) model
The All-island power system, representing the
electrical grids of the Republic of Ireland and
Northern Ireland, has a target of supplying 37% of
electricity with wind power by 2020. This presents
a considerable integration challenge, in particular
associated with the increasing number of periods
when there is too much wind power and not enough
demand on the system, requiring wind power to be
turned off or ‘curtailed’.
The authors previously estimated potential
curtailment on the All-island system in 2020 using
a novel model. The model was validated using
actual wind output and curtailment data from 2011,
and produced results for 2020 indicating
curtailment levels ranging from 5.6% to 8.5% -
consistent with previously published estimates.
This paper expands the previously published model
to include: simulation of dispatch of conventional
generation based on merit order; a representation of
variable prices within a wholesale electricity
market; and the operation of electrical energy
storage within the system. The model is used to
estimate the installed wind capacity required to
supply 37% of electrical demand and the potential
for storage to reduce the capacity required to meet
this target. Finally, the model has been adapted to
MS Excel and made available to download for free.
