Impact of Smart EVs on Day-Ahead Prices in the French Market

Abstract : This chapter examines the impact that the introduction of electric cars would have on day-ahead electricity prices over the next 10-15 years, using the French grid as a case study. The authors are interested in statistically predicting the impact of EVs on the network by simulating the offers to buy and sell electricity on the day-ahead market. The two scenarios for recharging the EVs considered include the case where the grid can draw power from the batteries when prices are high--the vehicle-to-grid (V2G) concept. Most studies on the impact of wind power on day-ahead prices make two strong assumptions, namely that the demand is inelastic and/or supply is the same as the merit order. The major contribution of the chapter is to propose a method for modeling the offers to buy and sell power on the wholesale market in the absence of such restrictive assumptions.
