集群风储联合系统广域协调控制及利益分配策略

针对多个风储联合系统的协调问题，提出了多风储联合系统集群广域协调控制框架，构建了考虑风电时空相关性的风储系统多模式优化调度模型，进一步基于合作博弈理论提出了集群收益分配策略。采用实际风电数据对所提模型和策略进行了仿真验证。仿真结果表明:广域协调控制可最大化集群收益，提高风电整体可控性和储能运行效率；基于合作博弈理论的集群收益分配策略，可实现集群控制中自身利益与整体利益相协调，激励风储系统积极参与集群控制。

Wide-area Coordinated Control and Benefit Assignment Strategy of Clustering Wind-Energy Storage Integrated System

To solve the coordinated problem for multiple wind-energy storage integrated systems, this paper proposes the clustering wide-area coordinated control frame for multiple wind-energy storage integrated systems. The multi-pattern optimized dispatching model considering the spatial-temporal correlation of wind power is constructed. Furthermore, a strategy based on cooperative game theory is proposed to allocate the cluster benefits. Simulation verifications of the proposed model and strategy are made by using actual wind power data. Simulation result indicates that the wide-area coordinated control can maximize the profit of the cluster, improve the controllability of wind power and operation efficiency of energy storage. The assignment strategy of cluster benefit based on cooperative game theory can coordinate the benefits of the individual and the cluster, which can encourage the wind-energy storage system to actively participate in the cluster control.
