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.
