摘要
微网是一种可将各种分布式电源组合起来为当地负荷提供电能的中、低压小型电网,具有并网和孤岛2种运行模式,能提高负荷侧的供电可靠性。文中总结了目前世界范围内的微网发展状况,按结构和控制模式对现存的微网实验室和示范工程加以分类,并进行了深入的分析,依据国外一些微网实验室和示范工程的建设经验给出了对中国微网建设具有指导意义的建议。
Microgrids are small low or medium voltage electric networks which utilize various distributed generators to serve local loads. A microgrid system can operate in grid-connected or islanded mode, and hence increase the reliability of energy supplies. This paper summarizes the microgrid research and development efforts currently happening around the world. According to their structural characteristics and control approaches, the existing microgrid laboratories and demonstration projects are classified and thoroughly analyzed. Based on the experience gained from some successful overseas microgrid laboratories and demonstration projects, guidance and suggestions for the future development of microgrids in China are orooosed.
