doi:10.3969/j.issn.1000-7229.2019.03.005

Abstract

Abstract: Utilizing vehicle to grid (V2G) technology， electric vehicles (EVs) can behave as mobile energy storage units to participate in power grid operation. Due to the traffic behavior characteristics， the V2G response capability boundaries of EV considering time， energy and battery restraint are constructed. Then，the electric vehicles connected to the grid are divided into two types: responsive and non-responsive. Finally， time-limit V2G response capability forecast models for EV and EV groups are established. On the other side，the value-at-risk(VaR) method is introduced into the sizing of energy storage capacity， and a reliability-at-risk(RaR) model is established to calculate the storage capacity under a certain reliability confidence level. The methods proposed in this paper are applied and verified in the examples.

Key words: electric vehicles, V2G response capability, Monte Carlo, energy storage, value-at-risk (VaR), reliability
