A Voltage Control Method for Distribution System by Coordinating LRT and DG Power Factors

Abstract

Currently, the introduction of renewable energy is progressing globally toward the realization of a low-carbon society. Many studies have been conducted on voltage control of distribution systems. These methods are roughly classified into two methods based on the control target device owners. One is owned by utilities, other is customers. In this study, we propose an efficient voltage control method by coordinating utility owned device and customer owned device. In order to confirm the performance of the proposed method, simulations were performed on a model system. The simulation results show that the proposed system is able to control the voltage by coordinating use of utility and customer owned devices.
