提出了一种基于晶闸管控制的串连电容器(thyristor controlled series capacitor，TCSC)技术和粒子群优化算法的电力系统阻塞疏导方法。首先根据线路灵敏度分析确定安装TCSC的线路；然后提出了电力市场环境下电网中含有TCSC装置的阻塞疏导计算数学模型；最后运用粒子群优化算法对这一数学模型进行参数优化，达到疏导电网阻塞的目的。IEEE 14节点系统算例表明，基于TCSC技术进行电网阻塞疏导是有效、合理的。

Studies on Congestion Management of Power Systems Based on TCSC and PSO

Based on the technology of thyristor controlled series capacitor (TCSC) and particle swarm optimization (PSO),a congestion management approach for power systems is proposed. According to the result of sensitivity analysis,the authors firstly decide the transmission line where the TCSC device should be installed; then a mathematical model for the congestion management calculation of power network containing TCSC device under the electricity market environment is proposed; finally by use of particle swarm optimization(PSO),the parameters of the proposed mathematical model is optimized to achieve the goal of congestion management. The calculation results of IEEE 14-bus test system show that the TCSC technology based congestion management is reasonable and effective.
