Abstract
Abstract
The inaccuracy of reactive power demand analysis in practical power system often leads to the problem of low voltage stability margin. In this paper, the analysis method of voltage-reactive power correlation is proposed, which is used to solve the inaccuracy of reactive power demand analysis. The proposed method can quickly analyze the reactive power demand of each region only according to the voltage stability margin index. The local reactive power compensation and the input reactive power on the system side are considered in the derivation of the voltage stability margin. Therefore, the proposed method accords with the practice of power system. The effectiveness of the proposed method is proved by a simple system.
