摘 要: 介绍了内点法的分支原对偶路径跟踪法,并针对某区域电网的无功电压现状,建立以网损最小为目标函数,并兼顾电压质量最好进行无功优化,有效降低了系统的有功网损,同时电压质量也得到提高。该优化方法对于大规模电网的无功优化具有一定的指导意义。

Abstract: Introduction was made to the branch primal-dual path tracking method of interior point method. Aiming at reactive voltage present state of a local grid, this paper established the objective function with the minimum network loss for reactive power optimization in concurrent of best voltage quality carrying out reactive power optimization to effectively reduce active network loss of the system. The optimization method for reactive power optimization of large-scaled grid has certain guiding significance.
Key words: reactive power optimization; active power loss; primal-dual path following method; improved interior point method
