利用榆林地区2012年风电场与光伏电站的实际出力资料与NOAA天气预报模式Weather Research and Forecasting Model（WRF）模拟的2012年光伏电站出力资料，对2012年榆林地区光伏出力情况进行了计算，并对风电与光伏不同装机比例情况下的峰谷差变化进行了讨论，结果表明风电与光伏装机在1∶0.1、1∶0.2的情况下，相对于风电的峰谷差变化不明显，只有23%的情况下增幅超过10%，其余情况下峰谷差不变或者减小，随着光伏比例的增加，风电与光伏叠加后的峰谷差与只有风电相比明显增加。

In this paper,the actual wind farm data in Yulin area in 2012 and the PV power output data simulated through NOAA weather forecast model Weather Research and Forecas-ting Model (WRF) are used to calculate the output of the photovoltaic power in 2012,and the peak-valley changes under different ratios between the wind power and the photovoltaic power installed are discussed. The results show that when the ratio between the installed wind power and the installed photovoltaic power is 1∶0.1 and 1∶0.2,the peak valley difference does change significantly,only at 23%the increase will exceed 10%while in other cases the difference remains unchanged or reduced. With increase of PV power,however,the superimposed peak valley difference of wind power and photovoltaic power increases significantly compared with the only wind power.
