微电网系统在三明发展前景及可行性研究

摘要

微电网是一种新型电网，由各种分布式电源通过联络线与电网相连，由于供电与需求的不平衡关系，微电网可选择与主网之间互供或者独立运行，实现对配电网能源结构的优化。主要介绍了微电网中分布式电源，如燃料电池、光伏电池和风力发电机组等，并对其特性进行相关分析。%M icrogrid is a new type ofpow ergrid,and differentkinds ofdistributed pow ersupply connectto the grid through the link line.B ecause ofthe im balance betw een supply and dem and,the m icrogrid can choose the m utualsupply betw een the m ain netw ork, or independent operations, accordingly to optim ize the distribution netw ork energy structure. This paper describes the m icrogrid's distributed pow er supply,such as fuel cells,photovoltaic cells and w ind turbines,etc.,and their characteristicsare analyzed.
