Analysis of Optimal AVR Placement in Radial Distribution Systems using Discrete Particle Swarm Optimization

Abstract

Voltage Regulator has always been considered as an integral part of the distribution system response. There are several factors, which contribute to voltage collapse such as increased loading on distribution feeders, reactive power constraints, on load tap changer dynamics and load characteristics. The proposed DPSO method is suitable for voltage regulator placement in radial distribution systems. This paper focuses on achieving optimal voltage control with voltage regulators and then to decrease the total cost and losses, to obtain the maximum net savings. Proposed method makes the initial selection, installation and tap setting of the voltage regulators to provide a smooth voltage profile along the network.
