摘　　要：当大规模的电动汽车(plug-in hybrid electric vehicle,PHEV)和分布式发电(distributed generation,DG)接入电网时,车主充电行为的随机性和分布式发电的间歇性加大了对电网调节能力的要求。文章建立了电动汽车和分布式发电协调控制的多目标优化模型。该模型以等效负荷率最大、节点电压越限和损耗率最小、入网服务成本和车主充电成本最低为目标,动态调节电动汽车充放电功率,能很好地匹配负荷和分布式发电的功率波动,降低分布式发电间歇性对电网的影响。最后用实例进行仿真,并对结果进行了深入分析。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.
