In consideration of the characteristics of wind farm group connected to different transmission sections into the grid

an active power control strategy for wind power considering priorities of power generation with peak regulation constraints is proposed. The priorities of power generation of wind farms are set based on the limited extent of different transmission sections. The active power instructions of wind farms are calculated considering the acceptance capacity to the grid

the installed capacity and the power generation capacity of wind farms. In one control cycle

the coordination of peak regulation's and transmission sections' limits

and the target value of peak regulation checked

and the forced calculating of instructions are designed to take full advantage of acceptance capacity to the grid and the capacity of transmission sections. The clamping control strategy of high priority wind farms can effectively avoid the fluctuation of active power of wind farms in different transmission sections when the acceptance capacity to the grid is changed quickly. The actual operation of the Jibei power grid proves that the control strategy proposed is effective.
