Abstract: 
A coordinated grid-connected control strategy for PV batteryenergy storage hybrid power system with electric vehicle is proposed. PV, energy storage and electric vehicle models are built respectively. The front stage DC/DC converter of PV system utilizes maximum power point tracking control, and the bidirectional DC/DC is used for energy storage system and electric vehicle to keep DC voltage stable. The after stage DC/AC parallel inverters of the PV battery-energy storage hybrid power system with electric vehicle adopt constant DC voltage and constant reactive power control. The constant current and constant voltage control is adopted when electric vehicle is charged. The proposed control strategy is simulated by Simulink simulation platform, the simulation results are analyzed to verify the feasibility and effectiveness of the proposed control strategy.
