Abstract: Due to the characteristics of randomness and instability, wind power can not be connected to the grid in a large scale, and the wind curtailment is produced. Pumped storage power station has a good ability of “peak load shifting” to absorb the excess wind power. In this paper, taking the region of west Inner Mongolia where the phenomenon of wind curtailment is particularly serious during the heating season as an example, based on the actual data of power grid in region of west Inner Mongolia and pumped storage power station in Hohhot, the optimization model of wind power -pumped storage-heating combined operation is established. Through the comparative study, it is found that thermal power boilers can further consume wind power based on combining wind power and pumped storage, which enhances utilization efficiency of wind energy and reduces wind curtailment. In addition, the emission problem of coal heating pollutant is solved, and the shortage of fossil energy resources is alleviated to some extent.
