基于改进内点法的区域电网无功优化

摘要

Introduction was made to the branch primal-dual path tracking method of interior point method. Aiming at reactive volt-age present state of a local grid, this paper established the objective function with the minimum network loss for reactive power op-timization 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.%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。
