Autonomous frequency regulation control of V2G(Vehicle-to-grid) system

Abstract

V2G technology considers EV as an energy storage unit to interact with the grid, which is the inevitable trend of future development. Based on the decentralized V2G system, a control strategy was proposed by considering users' individual demands and SOC constraints of EV battery. A simulation study is carried out to demonstrate the electric vehicle for frequency regulation as mobile energy storage unit. The simulation results show that the proposed control strategy can not only suppress system frequency deviation but also achieve charging demand.
