摘要
采用改进的模拟退火优化算法对配电网进行无功优化计算,针对配电网无功优化问题建立优化计算的数学模型。以调节无功补偿容量、补偿点分布、变压器分接头位置为手段,实现无功优化目的。对实际配电网优化计算结果表明,该方法可有效降低系统网损,保证各节点电压稳定,提高电力系统运行的安全性和经济性。
The improved simulated annealing algorithm was applied to vat optimization in calculation of network distribution. The mathematical model of var optimization was also founded for distribution network. Vat optimization was realized by modulating var compensation capacity, location and the tap joint of transformer. The optimization in calculation results of practical distribution network certified that this method could decrease network loss efficiently, keep the node voltage steady and improve the running safety and the benefit of power system.
