微网是通过整合多种分布式电源、储能系统、可控负载的一种分布式的低压供电网，微网可以运行在并网和孤岛两种模式下：在并网运行时，大电网可以作为微网的重要支撑；在孤岛运行模式下，为保证重要负荷的供电，需要各微电源协调运行，从而使微网的总运行成本最小。采用改进粒子群算法对孤岛运行模式下的一个小型的微网系统算例进行研究，仿真计算结果表明了所提方法的有效性。
微網是通過整閤多種分佈式電源、儲能繫統、可控負載的一種分佈式的低壓供電網，微網可以運行在併網和孤島兩種模式下：在併網運行時，大電網可以作為微網的重要支撐；在孤島運行模式下，為保證重要負荷的供電，需要各微電源協調運行，從而使微網的總運行成本最小。採用改進粒子群算法對孤島運行模式下的一箇小型的微網繫統算例進行研究，倣真計算結果錶明瞭所提方法的有效性。

Microgrids are low-voltage（LV） distribution networks comprising various distributed generators, storage devices, and controllable loads that can operate either interconnected or isolated from the main distribution grid as a controlled entity. In the ormer mode, the power grid could be an effective support of the microgrid to satisfy the whole load demand in the microgrid; In the isolated operation mode, In order to ensure the power supply to the critical load, It is necessary for the micro-powers to coordinate their generation, so that the total operating costs of microgird could be minimized. The economic dispatch of a small microgird example in island mode was optimized by improved particle swarm optimization（PSO） method, simulation results show the effectiveness of the proposed method.
