Abstract:The operation of energy-storage type charging point coordinated with power grid, could not only reduce the cost of grid capacity expansion but also enables to provide ancillary service for the grid, and thus reduce the economic cost of the operation. In order to explore the impact of real-time pricing (RTP) incentives on the economic benefits of energy-storage charging points, this paper conducts a joint operation optimization energy scheduling study of energy-storage charging points participating in demand response. In this paper, we established the economic benefit function model of energy-storage charging points involving the demand side response mechanism with the consideration of considering RTP incentives. The economic utility maximization optimization is formulated and constrained by energy scheduling and capacity bound. To apply primal-dual decomposition methods, the joint operation optimization model is transformed into a typical convex optimization problem and the optimal energy scheduling is obtained. Based on real-world load profiles of storage capacity and economic cost parameter, the simulation results show the fast converge and profits earning of the proposed method.
