摘要
含高比例新能源新型电网的建设发展对调频辅助服务提出了更高的需求。针对这一问题,提出了一种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方法,在满足配电网运行经济性最优的同时,为输电网提供调频备用容量。建立分层分布式调度架构,协调调度层和集群自治层均采用分布式拓扑结构,各智能体与邻近智能体相互通信并完成个体计算任务;以灵活性特征表征分布式能源响应调频辅助服务请求的能力,构建两者集合之间映射的对应法则;建立协调优化调度模型,采用一致性算法求解得到最优功率方案和共识价格,并获得集群备用容量。通过算例仿真验证所提计及调频备用效益的协调优化调度方法的有效性,并结合典型通信故障场景分析分层分布式算法的鲁棒性。
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.
