摘要
分布式控制以其鲁棒性强、可扩展性强等突出优势,已逐渐取代集中式控制,成为高渗透率配电网优化控制的一种有效途径。文章研究了一种基于无功补偿设备和分布式电源分组协作机制的配电网分布式优化控制策略,将多个无功补偿设备或分布式电源聚合在一起,以基于领导者的一致性协议控制节点电压和交换功率。文章给出了分布式协同控制框架,各分组控制目标及一致性变量的选取,并证明了各控制组分布式控制算法的收敛性。通过IEEE14节点系统的仿真算例验证了所提出方法的正确性和有效性。
Distributed control,with its outstanding advantages of robustness and scalability,has gradually replaced centralized control as an effective way of optimal control for high permeability distribution networks.In this paper,a distributed control strategy based on reactive power compensation equipment and distributed generation grouping cooperation mechanism is studied.Multiple var compensators or distributed generators are aggregated to control node voltage and switching power based on leader-follower consensus protocol.The framework of distributed cooperative control,the selection of control objectives and consensus variables for each group are given,and the convergence of distributed control algorithm for each group is proved.The correctness and validity of the proposed method are verified by several simulations in IEEE14-bus system.
