Optimal placement of SVR considering plural load

Abstract

This paper presents a new approach to the optimal placement of a step voltage regulator (SVR) taking into consideration the installation of distributed generators (DG) based on a genetic algorithm (GA). In this case, it is necessary to solve problems such as the upper and lower limits of voltage at each node and line capacity. In addition, considering that the load and output of DG changes, it is important to solve more than one of these problems. In order to solve these problems, the conventional GA was improved and the proposed method was applied to the complex operative conditions of a distribution power system. © 2011 The Institute of Electrical Engineers of Japan.
