摘要
随着更多的分布式电源接入,微电网及其群落出现在配电网末端。如何合理规划设计微电网及其群落成为智能电网发展必须解决的关键问题之一。从运营模式和技术形态2个方面阐述微电网群的主要特征,比较微电网群与其他分布式电源接入配电网技术解决方案的区别。接着,提出微电网群的一般规划设计流程。在此基础上,结合广西猫儿山地区的实际供电需求和条件,完成了猫儿山微电网群示范工程的方案设计,并对其合作运营模式成立的条件进行校验。研究工作拓展了微电网群的实际应用,可为微电网群相关规划设计和运行管理提供借鉴依据。
With increasing integrations of distributed generations (DGs), microgrids and multi-microgrids appear at the terminals of distribution systems. Their appropriate planning and design turn to be one of the key issues for smart grid development. Firstly the main characteristics of multi-microgrids were discussed in the aspects of operation modes and technical forms in this paper. Comparisons between multi-microgrids and other methods for DG integration and operation were conducted. A general design procedure for multi-microgrids was proposed. The design of a multi- microgrids pilot project at Mao'er Hill in Guangxi Zhuang Autonomous Region was introduced based on the practical demands and conditions of energy supply. The cooperation mode requirements of the multi-microgrids design were verified then. The work extended the practical applications of multi-microgrids, and could be used as a reference for related planning, design, operation and management.
