Abstract
The article estimates the costs of plug-in electric
vehicles (EVs) in a future power system as well as the
benefits from smart charging and discharging EVs (smart
EVs). To arrive in a good estimate, a generation planning
model was used to create power plant portfolios, which
were operated in a more detailed unit commitment and
dispatch model. In both models the charging and
discharging of EVs is optimised together with the rest of
the power system. Neither the system cost nor the market
price of electricity for EVs turned out to be high
(36-263 /vehicle/year in the analysed scenarios). Most
of the benefits of smart EVs come from smart timing of
charging although benefits are also accrued from
provision of reserves and lower power plant portfolio
cost. The benefits of smart EVs are 227 /vehicle/year.
This amount has to cover all expenses related to enabling
smart EVs and need to be divided between different
actors. Additional benefits could come from the avoidance
of grid related costs of immediate charging, but these
were not part of the analysis.
