When large-amount of plug-in hybrid electric vehicles(PHEV) and distributed generation(DG) are integrated into power grid,the randomness of vehicle owners’ charging behavior and the intermittence of DG make the requirement to regulation capability of power grid raised.A multi-objective optimization model for coordination control of PHEV and DG is established,in which the maximum equivalent load rate,the minimum out-of-limit voltage and power loss ratio and the lowest service cost of vehicle to grid(V2G) and charging cost of PHEV owners are taken as the objectives.Using the proposed model,the charging/discharging power of PHEV can be dynamically adjusted;the load fluctuation and the output fluctuation of DG can be well matched,thus the impact of DG’s intermittence on power grid can be alleviated.The simulation of an actual 10kV feeder connected with PV generation and wind farm is performed and the results are analyzed in depth.
