Unit Commitment with Price Demand Response based on Game Theory Approach

Unit Commitment program is an important study in the operation of power systems which objects to achieve the minimum system operating cost by considering network and unit constraints. In conventional UC, competition between independent units to maximize their profits is not considered. To overcome this shortcoming, in this study, a game theory-based approach has been employed to address the above points. In this regard, we introduce two types of players including power plants and system operator, and solve UC problem with Nash Cournot and Nash Bertrand techniques. Indeed, the main goal of this study is to find a way that maximizes the profit of the system operator by considering the independent units' behavior. To verify the robustness of the proposed method, the introduced UC approach is employed on the IEEE six-bus power system.
