Abstract

This paper considers the use of reactive power allocation to control voltage stability. Reactive power shunt compensation is considered an important strategy in controlling voltage stability, and, therefore, a new method of determining the best location for shunt compensation is presented. The method is based on the sensitivities of the change in reactive power flow with respect to the change in reactive power injection. The amount of shunt compensation to be allocated is determined by using a linear programming optimization technique. The technique incorporates voltage collapse proximity indicators based on line stability factors in the objective function formulation with the aim of minimizing the risk of voltage collapse and improving the voltage profile in the system. Test results have confirmed the accuracy of the proposed methods in determining the location and size of reactive power devices by comparing the methods with other published methods.
