基于并网/孤岛不同策略的多换流器微电网运行控制策略研究

Research on the Operation Control Strategy of Multi-converter Microgrid Based on Different Strategies of Grid Connected and Islanded Operation

当前随着各国环保要求越来越高,清洁能源的发展势在必行,因此含多换流器微电网如何实现并网和孤岛不同工况下的平稳运行至关重要,针对这一问题,提出基于并网/孤岛不同策略的多换流器微电网运行控制策略。文章构建由风光储组成的多换流器微电网结构,来验证基于并网/孤岛不同策略的多换流器微电网运行控制策略,并在大型电磁暂态软件PSCAD/EMTDC中搭建微电网系统模型,开展研究。

With the increasing environmental requirements in various countries,the development of clean energy is imperative.Therefore,how to realize the smooth operation of grid connection and island under different working conditions is very important.In view of this problem,the paper proposes the operation control strategy based on different strategies of grid connection and island.In this paper,a multi-converter microgrid structure composed of scenic parts is constructed to verify the operation control strategy based on different strategies of grid connection and island,and to build the microgrid system model in the large electromagnetic software of PSCAD/EMTDC.
