A differential game approach to distributed demand side management in smart grid

摘要: Smart grid is a visionary user-centric system that will elevate the conventional power to one which functions more cooperatively, responsively, and economically. Dynamic demand side management of key issues enable implementation smart grid. In this paper, we use framework dynamic games model distribution management. The market price characterized as state using sticky model. A two-layer optimization established. At lower level, for each player (such household), different appliances are scheduled energy consumption. upper game used capture interaction among players in their responses through price. We analyze N-person nonzero-sum stochastic differential characterize its feedback Nash equilibrium. special case homogeneous users investigated detail provide closed-form solution optimal response. From simulation results, demonstrate response strategy from game-theoretic study behavior parameters.
