Fuzzy multi-agent based voltage and reactive power control

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.
