摘　　要：微电网作为一个大小可以改变的智能负载,是大电网的有力支撑.文章对微网与大电网的并离切换、并网控制策略进行了深入的研究.在并离切换方面提出了主动型的无缝切换和被动型的有缝切换两种方式;在并网控制策略上提出了平滑分布式电源波动、计划输出控制、能量型和功率型储能的协调控制、储能削峰填谷四种方式;并对离网控制和负荷控制策略进行了相应探讨.As an intelligent and adaptable load,the micro-grid（MG） power system provides a strong support for the large power grid.This paper focuses on an in-depth research on the switch between the connection and islanding of the micro-grid and the large power grid,and the grid-connection control strategy.Two switching methods including the active seamless switch and the passive seamed switch between connection and islanding are proposed.Four methods of the grid-connection control strategy are given,including the distributed power fluctuation smoothing,the planning output control,the coordinated control of energy and power energy storage and the energy storage peak load shift.Then the grid-islanded control strategy and load control strategy are also discussed.
