In order to maintain the system voltage within the optimal range and to prevent voltage instability phenomena before they occur, a variety of phase modifying equipment are installed in optimal locations throughout the power system network and a variety of methods of voltage reactive control are employed. The proposed system divides the traditional method of controlling voltage and reactive power into two subproblems: “voltage control” to adjust the secondary bus voltage of substations, and “reactive power control” to adjust the primary bus voltage. In this system, two types of agents are installed in substations in order to coordinate voltage control and reactive power control. In order to verify the performance of the proposed method, it was applied to a model network system. The results confirm that our proposed method is able to control violent fluctuations in load. © 2012 Wiley Periodicals, Inc.
