Wind power, with its non‐polluting characteristic and free access, has been widely developed in the grid, and this trend is expected to continue in the future. However, the high penetration of wind energy brings challenges to the operation of power system. Demand response (DR) provides a better way for electric utility customers to match the power demand and supply. This article aims at enhancing the economy of high wind power penetration system operation. Firstly, the principle and characteristic of demand response is analyzed. Then a system operating cost optimization scheme considering the demand response is proposed. With the demand response, simulations proved that the capacity of system for accepting wind energy is improved, and the operating cost of system is reduced.
