Multi-agent based distributed reactive power control method

Abstract

In order to maintain system voltage within the optimal range and prevent .voltage instability phenomena before they occur, a variety of phase modifying equipment is installed in optimal locations throughout the power system network and a variety of methods of voltage reactive control are employed. In this paper, the voltage reactive control problem is considered as the two sub problems such as voltage control and reactive power control. The proposed multi-agent system intends to resolve the reactive power control sub problem. In this system, three types of agents are installed in substations in order to maintain the primary bus voltage within the operation limit by allocating the reactive power. In order to verify the performance of the proposed method, it has been applied to the model network system. The simulation results show that the proposed method is a promising approach to keep the primary bus voltage within the operational limit by changing the reactive power allocation. © 2009 The Institute of Electrical Engineers of Japan.
