Abstract:

With the development of wind power scale in Gansu， the feature of anti-peaking of wind power makes the peak regulation of power grid more and more serious. So for the safe and stable operation of power system， part of grid-connected wind turbines have to be removed， which may cause great waste of equipment. In view of the above situation， high energy-consumption enterprises were suggested to actively participate in the wind power consumption and the peak regulation mode of power grid was proposed. Then， the internal transfer load and increasing load in high energy-consumption enterprises were studied with considering the constraints of wind power’s price and peak regulation， and the fluctuations of wind power output were calculated with using optimal prediction function to control optimization algorithm. Finally， simulation research was carried out in Matlab platform， according to the actual wind data and the transfer load of high energy-consuming enterprises. These results show that the wind power output can be smooth. Compared with the traditional peak regulation mode， the active participation in peak regulation of high energy-consumption enterprises can not only improve the wind power consumption capacity in province， but also relieve the pressure of peak regulation of power grid. Meanwhile it can save the electricity cost of high energy-consumption enterprises， in the support of relevant electricity price policy.
