FEASIBLE METHOD FOR OPTIMAL CAPACITOR PLACEMENT IN A DISTRIBUTED SYSTEM BY USING GAME THEORY

The utilities are interested on economic and optimal projects which improve their services to customers. These projects should increase the utilities’ profit as well. Reactive power compensation as a useful and practical approach has been studied very much. One way of reactive power injection is installation of constant capacitors that result in voltage profile improvement, power losses and cost decrease. The present paper’s goal is to offer new flexible designs using Game Theory concepts. Power loss is first objective while capacitor and power loss cost are considered as second objective. The optimization algorithm, Strength Pareto Evolutionary Algorithm (SPEA), proposes some optimum plans for supplying system reactive power. In order to show the suggested method’s capabilities, the results are compared with GA which proves the superiority of SPEA.
