摘　　要：微网系统在一个局部区域内直接将分布式电源、储能单元和用户负荷联系在一起,能够有效提高能源利用效率,降低配电网的负担,改善电能质量及供电可靠性。在对微网关键技术和国内外示范系统建设分析的基础上,以漕溪微网系统为例,介绍了一种微网系统的总体架构和控制系统结构,并重点对微网在并网运行、离网运行及其相互切换过程中的不同控制策略进行深入分析。Microgrid system, directly connecting regional distributed generation, energy storage unit and customer load together, can effectively improve energy efficiency, reduce the burden of distribution network, and enhance power qual.ity and supply reliability. Based on the analysis of microgrid key technology and demonstration system construc- tion at home and abroad, taking Caoxi microgrid system as an example, this paper presents the microgrid system＇s general architecture and control system structure, with a focus on the different control strategies for microgrid in the grid-connected operation, the off-grid operation and the switching process respectively.
