摘要
作为能源互联网的重要组成部分,微电网控制技术得到了广泛关注。介绍了微电网的概念和结构,分析了典型的微电网结构模型。阐述了微电源逆变器的三种控制方式,即恒功率控制、恒压恒频控制及下垂控制。结合控制方式,对微电网的分层管理体系进行了分析,并对微电网运行控制技术的发展前景进行了展望。
As an important part of the internet energy system,the microgrid has been researched widely. This paper introduced the concept and structure of the microgrid and a typical microgrid structure model. The three control strategies of micro-sources inverters has been described,including constant power control,constant voltage and frequency control,and droop control. Finally,the hierarchy management structure of microgrid was analyzed according to the fashion of inverters combinations,and the prospects for the development of microgrid control technology was presented.
