摘　　要：针对含分布式电源的配电系统,特别在考虑了由分布式电源和负荷组成微网运行的情况下,建立了以恢复负荷最多、开关操作数最少为目标的供电恢复模型。在提出配网调度中心、微网、分布式电源三者的分层协调控制策略的基础上,应用多代理理论,建立了一个由全系统控制协调代理(CAG)、微网控制代理(MGAG)、分布式电源代理(DGAG)以及母线代理(BAG)组成的多代理系统,在保证配电网辐射状运行、满足配电网电压与电流及馈线容量等约束条件的情况下进行供电恢复。通过分析一个含2个变电站、14条母线和4个分布式电源的配电系统的单重及多重故障供电恢复问题验证了该方法的有效性。In terms of the distribution system with distributed generations （DGs） especially considering the operation of microgrids （MGs） composed of DGs and loads, a service restoration model aiming at the restoration of the most load with the least number of switching actions is built. On the basis of the proposed hierarchical control strategy among dispatching center of distribution network, MGs and DGs, this paper builds up a multi-agent system for service restoration of distribution system containing DGs and/or MGs. The proposed system applies the multi-agent theory with the satisfaction of the restriction of radial supplying, voltage, current and power capacity limits of distribution network, The proposed multi-agent service restoration system is composed of single central control agent （CAG）, several distributed generation agents （DGAGs） and micro-grid agents （MGAGs）, and many bus agents （BAGs）. The analysis of the service restoration problem of a distribution system with two substations and fourteen buses containing four DGs after occurrence of single fault and multi faults is given in the paper.
