摘　　要：配电网大量接入分布式电源和储能装置后,集中式的管理模式实时性较差,因此文章提出3层控制结构,将主动配电网进行区域划分,并在每个区域中配置协调控制器进行区域自治控制。根据馈线控制误差(feeder control error,FCE)指标,建立了实时平抑区域运行状态与最优目标之间差异的区域控制机制,据此提出了分层分布控制器与源网协调控制器的模型。根据FCE指标的不同形式,提出馈线定交换功率、区域独立自治和区域协同自治3种控制模式,以适应不同电网需求。最后通过广东某主动配电网示范现场算例的仿真分析,验证了所提分层分布控制策略的合理性和有效性。With the integration of distributed generation （DG） and energy storage system （ESS）, the real-time performance of centralized management is poor in distribution network. Therefore, a three-layer control structure, dividing active distribution network （ADN） into regions, is proposed and each region is equipped with several coordinate controllers for autonomous coutrol. According to the indicator of feeder control error （FCE）, the control mechanism, which eliminates the differences between real-time operating status and global optimized status, is established and the models of hierarchical and distributed controller and source-network coordinate controller are proposed. Three kinds of control mode, the constant feeder exchange power mode, regional autonomous control mode and regional cooperative control mode, are put forward to adapt to different occasions. The effectiveness and validity of ADN hierarchical and distributed control strategy is verified with the simulation in an ADN demonstration site in Guangdong.
