摘要

并联和串联无功补偿是提高电力系统电压稳定裕度的两种有效途径。本文提出了一种定位开关并联电容器和串联电容器的方法,使它们具有在一组规定的突发事件下重新配置为安全配置的能力。新开关控制的最优位置是通过在表示开关离散配置的图上进行前向/后向搜索得到的。以一个改进的WSCC 9总线系统为例,验证了该方法的有效性。

Linear complexity search algorithm to locate shunt and series compensation for enhancing voltage stability
Shunt and series reactive power compensation are two effective ways to increase the voltage stability margin of power systems. This paper proposes a methodology of locating switched shunt and series capacitors to endow them with the capability of being reconfigured to a secure configuration under a set of prescribed contingencies. Optimal locations of new switch controls are obtained by the forward/backward search on a graph representing discrete configuration of switches. A modified WSCC 9-bus system is adopted to illustrate the effectiveness of the proposed method.
