摘    要:针对目前微电网组成及控制复杂,快速实现及扩容难的现状,提出了一种工程实用的模块化分布式光伏发电独立微电网结构,以实现快速组网、安全及高效运行。对该独立光伏微电网的运行原理、关键电力电子装置以及模块间调度控制策略等进行了分析设计。基于该拓扑结构,在海岛进行了光/柴/蓄独立光伏微电网实证研究,实现了海岛负荷不间断供电运行。进行了海岛光伏微电网运行状态的测试分析,试验结果验证了该微电网架构的有效性,并对存在的问题提出了建议。

关 键 词:微电网  分布式发电  控制  光伏  双向变流器

Abstract: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.
Keywords:microgrid  distributed power generation  control  photovoltaic  bi-directional converter
