摘　　要：为保证非理想通信环境下主动配电网的安全经济运行,应用多智能体系统一致性协同理论,提出了基于一致性变量信息交互的具有自主控制能力和高拓展性与可靠性的多源分布式协同调控策略。该策略为改善非理想通信环境下一致性算法收敛性能,引入调整增益函数,利用熵权法调整状态转移矩阵;为精准跟踪配电网联络线功率指令值,在联络线功率补偿控制信号中引入了积分控制项;针对分布式电源节点通信故障的情况,提出了结合集中式通信的变结构通信策略。最后,通过算例仿真验证了该策略的有效性。To ensure the safe and economic operation of active distribution network in a non-ideal communication environment,a multi-source coordinated control strategy is proposed using the theory of multi-agent system coordination,which is based on the information exchange of consensus variables and has an automatic control capability,a high flexibility and a high reliability.To improve the convergence performance of the consensus algorithm in the non-ideal communication environment,a gain adjustment function is added,and the entropy weight method is used to adjust the state transition matrix.PI control is introduced into the control signal of tie-line power to guarantee the accuracy of tracking the control signal of tie line power given by the distribution network control center.In addition,to deal with the communication failures of distributed generators,a flexible structure communication strategy combined with centralized communication is proposed.Finally,the simulation result of an example verifies the effectiveness of the proposed strategy.
