随着西北地区风电并网规模的增大，结合西北水电资源丰富、调节性能好的特点，考虑负荷特性、电源特性等，提出了水电与风电协调运行的思路，给出了水电、火电为风电调峰的调峰能力计算方法。该方法先根据水电与风电协调运行的原理推导水电可平衡的风电出力，再利用电力系统运行模拟计算程序计算火电可为风电提供的调峰能力。该方法对水电资源丰富地区风电接入后电网调峰能力的研究有借鉴意义。

Along with the growth of numbers of large-scale wind farms connected with Northwest China power gird, based on the feature that Northwest China is rich in hydroelectric resources with good regulation performance and considering characteristics of loads and power sources, a principle for coordinated operation of hydropower stations with wind farms is proposed, and a method to calculate the ability of peak load regulation of wind farms by thermal power plants and hydropower stations instead of wind farms themselves is given. Firstly, according to the principle of coordinated operation of hydropower station with wind farms, the wind power output that can be balanced by hydropower station is derived; then by use of power system operation simulation program the regulation capacity that the thermal power plants can provide for peak load regulation of wind farms is calculated. The proposed method is available for reference to the study on the peak load regulation ability of such power grid, which locates in the region that is rich in hydroelectric resources, while large-scale wind farms are connected with it.
