针对微网结构及其控制策略复杂、难以快速实施和扩展的现状，本文提出了一种基于分布式光伏发电的实用工程单机微网，实现快速建设和安全高效运行。研究了该系统的结构与运行机制、电力电子设备开发、能源管理与调度策略等关键技术。在此基础上，在岛上构建由光伏、柴油发电机组和蓄电池组成的示范微电网，并产生不间断电源。通过单机微网运行测试分析，验证了微网架构的有效性，并对存在的问题提出了建议。
In the view of the situation that structure of micro-grid and its control strategy are very complex, as well as difficult to fast implement and expand, this paper proposes a practical engineering stand-alone microgrid based on distributed photovoltaic generation, to realize fast construction and safe and efficient operation. The key technologies such as construction and operation mechanism, the power electronic device development, and energy management and dispatch strategy are studied. Based on the topology, the demonstration microgrid composed of photovoltaic, diesel generator, and storage battery is constructed on the island, and an uninterruptible power supply is produced. Operation test analysis of the stand-alone microgrid verifies the effectiveness of the microgrid architecture, and some suggestions are recommended for the problems existed.
