Fuzzy Multi-Agent Based Voltage and Reactive Power Control

Abstract

. Variations in load and generation profiles cause

overvoltages leading to equipment insulation failure and

undervoltages, which impact voltage stability margin. Voltage

and reactive power control aims to keep the voltage profiles

within desired limits and reduce power losses. In this paper

multi-agent system based on Java technology and adaptive fuzzy

logics algorithms are implemented to control voltage and reactive

power. Agents communicate with each other using Foundation

for Intelligent Physical Agents (FIPA) to be able to achieve their

objectives. A fuzzy agent controls the voltage at the busbars.

Multi-agent systems make it possible to do three hierarchal

voltage control in distribution systems.
