A multi-agent systems for voltage control of distribution networks by coordination power factors of distributed generators

This paper proposes a method for the coordinated control of power factor by means of a multi-agent approach. The proposed multi-agent system consists of two types of agent: feeder agent (F_AG) and bus agent (B_AG). In the proposed system, the F_AG plays as an important role, which decides the power factors of all distributed generators by executing the load flow calculations repeatedly. The voltage control strategies are implemented as class definitions of Java into the system. In order to verify the performance of the proposed method, it has been applied to a typical distribution model system. The simulation results show that the system is able to control very violent fluctuation of the demands and the photovoltaic generations (PVs).
