Research on the location of SSSC and optimization of network loss

为提高电力系统运行的可靠性和经济性,引入线路有功潮流性能指数,采用有功过负荷的严重程度作为指标,根据SSSC参数对其产生影响的灵敏度系数大小来确定SSSC最佳安装地点。建立以有功损耗最小的含SSSC的网损优化数学模型,将SSSC以等效注入功率模型加入到等式约束条件中,将模拟退火引入到改进粒子群算法中进行网损优化控制变量的获取,增强了全局搜索能力。以标准IEEE-14节点为例进行计算,验证了模型和算法的有效性。

In order to enhance the reliability and economy of power system,the author,therefore,determines the best location of SSSC according to the sensitivity coefficient by introducing performance index of active power flow with the severity of active power overload presenting as the index. The mathematical model of network loss optimization with minimum active loss SSSC is established. With the model,the ability of global searching is enhanced by acquiring the control variables for network loss optimization with the addition of SSSC,presenting as equivalent power injection model,into the constraint condition and simulated annealing into improved particle swarm algorithm. Taking the standard IEEE- 14 node as the example,the result of the calculation verifies the effectiveness of the model and the method.
