Vehicle-to-grid systems for frequency regulation in an islanded danish distribution network
Electric vehicles (EVs) have gained significant attention
in the recent years due to their prospects in reducing greenhouse
gas emissions benefitting the transportation sector directly
and the electricity sector indirectly. Vehicle-to-grid (V2G)
systems using the battery storages of electric vehicles could
provide power system ancillary services in the form of power
balancing reserves to support the large-scale integration of
variable renewable energy sources like wind power. This paper
investigates the dynamic frequency response of an islanded
Danish distribution system operation with large amount of wind
power supported by the Vehicle-to-grid systems. The power
system simulations are analysed for scenarios with 48% and
65% of wind power penetration. The simulation results show
that the V2G systems provide a faster and stable frequency
control than the conventional generation units. V2G systems can
be considered as a flexible solution for frequency regulation in
future electric power systems.
