摘要
为更好地研究和利用分布式电源,将其和负载作为一个子系统,在配电网的基础上引入微电网;分析微电网的概念、特点及工作方式,并对含微电网的配电系统进行可靠性评估;通过算例分析,验证了微电网的接入有助于改善部分负荷点的停电频率和停电时间指标,以及配电系统的可靠性指标。
In order to make better research and use of distributed generations,distributed generations and associated loads are viewed as a subsystem,and the concept of microgrid is introduced based on the distribution system.The concept,characteristics and operation modes of the microgrid are analyzed;a reliability assessment of distribution system with microgrid is made.Case study shows that the microgrid helps to improve the outage frequency and duration indices of some load points as well as the reliability index of distribution system.
