安全域视角下的有功安全校正优化控制方法
Optimization Control Strategy for Active Power Correction from Perspective of Security Region
摘要
Abstract
Traditional sensitivity method for active power corrective control are often based on the isolated indices of line loading rates,which may cause repeated or inefficient adjustment.The theory of security region is applied in analysis of problems in traditional methods.In the security region,the security distance from the operation point to the boundaries is obtained to quantify the security margin and provide guidance for optimal security control.On this basis,the concept of security distance sensitivity is proposed.Then,the generators are matched to opposite equal quantities according to their security distance sensitivities and actual adjustable abilities.Finally,the generators are selected in sequence prior to solving the linear programming problem.Simulation results of IEEE 39-bus system and a certain power grid show that this method is more intuitive and effective than the traditional one when dealing with multi-overload cases.In addition,as the security margin of other branches could also be considered in this method,repeated adjustment can be avoided.关键词
