Power demand side response potential and operating model based on EV mobile energy storage

Abstract

The demand side response potential of electric vehicles (EVs) serving as a mobile energy was analyzed based on the current charging characteristics of EVs, then a scheduling operation mode was put forward. Under the condition of grid demand side response, a price model based on time-sharing price, charging service fee and discharge price was established according to a game theory, in this model the constraints include grid load stabilization, the decrease of the EV owner's payment expense and the stable dispatching platform income. Through simulation, the demand side response capability of the electric vehicle based on the mobile energy storage can be obtained. It shows that the power load can be transferred amounts to 7%, the charging cost is reduced by 8%, and the income of the unified dispatching platform of the vehicle networking will increase by 22%.
