摘　　要：在国家能源转型背景和规划下,微网大规模接入已逐渐成为趋势,这不仅需要解决电网结构和运行对大规模微网接入的限制,而且需要解决大规模微网的互动机制,提升微网运行控制的柔性和经济性。针对微网群大规模接入问题,综合目前国内外解决方案和研究进展,提出了微网群互联和互动新方案,并对其中涉及的关键技术和难点的国内外研究进行了综述和分析,最后设计和分析了大规模微网群互联互动的典型案例。结果表明,通过多微网间能源互联互补,不仅能够实现微网之间相互支撑,互为备用,提高系统可靠性,也在更大范围实现了能源互补,使微网群更加有效地提升辅助服务,并参与到多种形式的电力市场中。With the ongoing transformation of national energy structure, there is a growing trend that large-scale micro- grid cluster integrates into the existing power system, therefore, not only microgid adaptability to network configuration and operational constraints are required, but also new interaction mechanisms both among microgrids and between the microgrid cluster and the upper utility grid should be investigated to improve control flexibility as well as overall econo- my. In terms of large-scale microgrid cluster integration, we proposed a novel solution for microgrid interconnection and interaction. A further endeavor was made upon reviewing and analyzing the associated key techniques and obstacles which have been spotted in current researches both at home and abroad. Moreover, a typical case study of multi-energy microgrid cluster was given. The results indicate that multi-microgrid interconnection not only enhances system stability via mutual supporting and mutual reserve, but also realizes energy implementation at a broader range and improves mi- crogrid flexibility in providing ancillary services, therefore greatly facilitates their participation in various types of electricity markets.
