计及调频备用效益的主动配电网分层分布式协调优化调度

The construction and development of new-type power grid with high proportion of new energy has put forward higher demands for frequency regulation ancillary services. To solve this problem，a hierarchical distributed coordinated optimal dispatch method of active distribution network considering the frequency regulation reserve benefits is proposed，which can provide the frequency regulation reserve capacity for transmission network while satisfying the optimal operation economy of distribution network. The hierarchical distributed dispatch architecture is established，and both the coordinated dispatch layer and the cluster autonomy layer adopt the distributed topology structure. Each agent communicates with the neighboring agents and completes individual computing tasks. The flexibility characteristics are used to characterize the ability of distributed energy resources to respond to frequency regulation ancillary service request，and the corresponding rule of mapping between the two sets is constructed. The coordinated optimal dispatch model is established，and a consensus algorithm is applied to solve the problem to obtain the optimal power scheme，consensus price and clusters’reserve capacity. An example is given to verify the effectiveness of the proposed coordinated optimal dispatch method，and the robustness of the hierarchical distributed algorithm is analyzed with typical communication fault scenarios.
