EVアグリゲータビジネスの可能性に関する検討

EV is expected to be one of flexible sources because it will spread explosively in the future. EV can charge and discharge electric power through V2G in the same way as stationary batteries, but the difference between EV and stationary batteries is uncertainties in the usable time and usable amount of the EV battery due to the operation of the EV owner. In this paper, those uncertainties are modelled by analyzing road traffic census data. Furthermore, stochastic programming is applied to maximize the profit of the EV aggregator by procuring electricity from the spot market for V2G. This paper also evaluates the EV aggregator business when it supplies the necessary downward regulation power when the supply of renewable energy exceeds the demand. Finally, in order to reduce the number of scenarios used for the simulation, backward scenario reduction is performed to shorten the calculation time and the performance is evaluated.
