Fast increase of intermittent energy such as wind energy is presenting great challenges to the traditional operation and control of power grids.To solve this problem，firstly，the fluctuation characteristic of wind power and the load characteristic of demand response（DR）are analyzed.Based on that，the overall technical framework of DR scheduling is proposed.Then，a multi-agent scheme is given.Furthermore，the multi-time scale rolling coordinated scheduling strategy which combines day-ahead scheduling，hours-ahead scheduling and real-time dispatch is studied.The effectiveness of the scheme，model and strategy proposed are demonstrated by simulation results on the IEEE39bus system.The experiments also show that the appropriate DR scheduling is feasible to balance the fluctuation of wind power and provides more peak-shaving and reserve service for grid-connection of new energy.
