Wide-area agent-based scheme for Volt/Var control with a cooperative framework based on game theory

摘要

A novel method for dynamic voltage control, followed by a power loss reduction in a wide area scheme, is presented in this study. The proposed scheme is based on a combination of multi-agent system and cooperative game theory concepts and determines appropriate coordination of reactive power resources for maintaining voltage security as well as lowering post-disturbance power loss of power system. In addition, the algorithm takes the advantages of previously proposed mechanisms by the authors, i.e. a predictive mechanism in taking remedial actions according to the trends of voltage magnitudes and impending remedial actions and a preventive approach providing an effective number of changes of taps in on-load tap changers. The acquired results of simulations, performed in the Nordic 32 test system, show the effectiveness and robustness of the proposed scheme.
