一种确定无功源最佳配置地点与数量的新方法

A New Method to Decide Optimal Allocation Sites and Number of Reactive Sources

将电压控制与无功源的配置相联系,考虑无功补偿点的补偿效应,给出了无功补偿主导节点的概念,并从保证系统安全性的角度出发,提出了一种根据无功补偿主导节点确定无功源配置地点和数量的方法。该方法以受扰后的系统电压偏移水平最小为目标函数,实现了无功源配置地点和数量的优化选择。IEEE30节点系统的仿真结果表明该方法可显著提高系统电压的稳定水平、降低系统网络损耗,验证了该方法的正确性和有效性。

Considering compensation effect of reactive source allocation and get voltage control in touch with the allocation of reactive sources, the authors put forward a concept of reactive compensation pilot buses; form the standpoint of ensuring power system security and according to the reactive compensation pilot buses a method to decide optimal allocation sites and number of reactive power sources is proposed. Taking the minimum voltage deviation level after disturbance as objective function, the proposed method can implement the optimal selection of allocation sites and number of reactive sources. The simulation results of IEEE 30-bus system show that the proposed method can evidently improve voltage stability of power system and reduce network losses, therefore the correctness and effectiveness of the proposed method are verified.
