Reactive Power Planning for Loss Minimization based on Harmony Search Algorithm

Abstract

This paper addresses an optimal Reactive Power Planning (RPP) of power system. The Static Var Compensator (SVC) is introduced into
power system in order to reactive power support and voltage control. The locations and the outputs of SVCs are determined using our proposed
optimal reactive power planning model. The proposed method optimizes several objective functions at the same time within one general objective.
The optimized objectives are minimization of total investment in reactive power support, average voltage deviation and minimization of total
system loss. These objective functions are one of the most important objectives for every transmission and distribution systems. Harmony Search
Algorithm (HS) is used to solve the optimization problem. The validity of the proposed method is tested on a typical power system.
