摘　　要：虚拟电厂(virtual power plant,VPP)可以聚合大量的分布式能源资源(distributed energy resources,DER)作为一个整体参与电力系统的调度。为实现VPP内部DER的高效调控,提出了一种虚拟电厂集群自治调度架构。为解决理想通信网络下VPP内部DER动态跟踪调度指令的优化问题,分别从集群层面和DER层面提出了调节成本一致性和调节时间一致性算法,通过本地相邻DER的信息交互,更新自治节点参数,降低了通信压力,且提高了求解效率。在此基础上,通过引入共识增益函数和虚拟共识变量,解决了实际通信网络中的传输延迟和噪声问题。仿真结果验证了所提算法的有效性和可行性。Virtual power plant(VPP)can aggregate a large number of distributed energy resources(DER)to participate in the dispatching of power system as a whole.In order to realize efficient control of internal DER in VPP,a virtual power plant cluster autonomous scheduling architecture was proposed.In order to solve the optimization problem of internal DER dynamic tracking scheduling instruction in VPP under ideal communication network,the algorithm of adjusting cost consistency and adjusting time consistency is proposed from the cluster level and DER level respectively.Through the information exchange of local neighboring DER,the parameters of autonomous node are updated,which reduces the communication pressure and improves the solving efficiency.On this basis,by introducing consensus gain function and virtual consensus variable,the transmission delay and noise problems in the real communication network are solved.Simulation results verify the effectiveness and feasibility of the proposed algorithm.
