摘　　要：结合微电网以及电动汽车的固有特性,建立微电网数学模型和电动汽车随机充放电功率数学模型.电动汽车通过自身的调度策略,结合切负荷操作,平滑微电网负荷波动,降低负荷峰谷差,确保其能适应接入微电网.此外,微电网为适应电动汽车的接入,采用以电网可靠性为目标,计及联网/孤岛模式切换的动态网架重构策略,从而达到新形势下电动汽车与微电网之间的交互适应性协同控制.以美国CERTS为算例进行分析,采用改进和声搜索粒子群算法,对含电动汽车的微电网综合调度运行策略进行研究,为未来电动汽车接入微电网提供一定的理论依据.Taking the characteristic of the microgrid and the EVs into account,the mathematical models of microgrid and EVs random charging power are built.The EVs scheduling mechanism is studied aiming at smoothing load fluctuating,reducing the peak-valley difference and eliminating the potential safety hazard with EVs access to the microgrid.In addition,the mathematical model considering the grid-connected/island mode is established.The microgrid can rapidly adapt to the EVs＇ penetration with the dynamic reconfiguration strategy aiming at the reliability in order to achieve the synergy under the new environment.Taking CERTS system for example,the microgrid optimal control strategy with EVs using improved harmony search particle swarm optimization algorithm is studied.
