Abstract
As wind farm’s capacity is large, and it has no frequency adjustment capability as conventional generators, its output variation will lead to frequency fluctuation dramatically. Based on the conception of isolated network and its existed frequency control mode, this paper studies and establishes the frequency control strategy to inhibit high frequency phenomenon after wind power is integrated, including 3rd and 2nd frequency adjustment strategy. Finally, 3rd frequency adjustment considers wind farm’s short-term and super short-term prediction, and coordination scheduling is carried out. Based on system frequency and wind farm output, 2nd frequency adjustment gives second level adjustment of conventional generator and wind farm. At last, by establishing the model of an isolated network containing a wind farm, the control strategy proposed is simulated and its validity is verified.
