Effects of electric vehicles on the spot market price

Impact of electric vehicles: Will German households pay less for electricity?

“…Controlled charging dampens this effect. By shifting the load to hours with a low electricity price, technologies with low variable costs, especially lignite-powered plants, achieve higher full-load hours in the analysed studies [9,11,13,17]. This results in lower prices than in the uncontrolled case.…”

“…Refs. [11][12][13]) also take a critical view of vehicle-to-grid concepts because of the associated high battery degradation.…”

“…While EVs are only used within a power plant deployment model as a medium to address further issues, e.g., CO 2 emissions, in Refs. [8][9][10], others explicitly address future impacts of EVs on power plant dispatch and electricity prices in Germany [13,16,17], Denmark [18] as well as Sweden, Norway, Denmark and Germany [11].…”

“…Taljegard et al [11], who combine a generation capacity investment model with a power plant dispatch model, demonstrate that particularly for a high share of EVs, system costs due to investments in generation technologies increase. The simulations by Hanemann and Bruckner [13] show that the additional demand due to EVs leads to increased demand peaks and correspondingly to an increase in the marginal costs of electricity generation. Controlled charging dampens this effect.…”

Risk-constrained offering strategy for a hybrid power plant consisting of wind power producer and electric vehicle aggregator

“…However, little researches have been done for the EV aggregator with both G2V and V2G services cooperating with WPPs as a price maker in the electricity market to increase their overall profits. In the future smart grid, EVs will be increasingly important to affect the electricity price, and flexible EV sources used in DR programs would bring more profits to the society [27,28]. However, renewable energy resources involve a lot of uncertainties, which would cause fluctuations and lead to economic losses for renewable energy producers [29].…”
