Abstract: The abandon wind power is serious in the three north areas in China.For the conventional allocation strategy cannot satisfy the impartial and open dispatchig, an active power allocation strategy based on twice weighted average capacity considering the factors of the generating capacity of wind farm, the grid related technological level, and the equipment operation status in the wind farms is proposed in this paper.This strategy eliminates the shortcomings of allocating the active power according to the installed capacity, promotes the technological transformation of wind farm, has positive influence on the security and stability of power system and promoting of wind power consumption.
