摘 要：China is rich in solar and wind energy resources,of which the proportion of China s power sources has been rapidly *** fluctuating and intermittent energy sources will bring significant challenges to the safe and stable operation power ***,making use of the spatiotemporal complementarities between different renewable energy resources is a feasible way to level fluctuating power especially when they have a widely geographical *** on the data provided by China Meteorological Administration(CMA),this research explores the spatiotemporal complementarities between wind and solar energy *** paper nondimensionalizes hourly wind speed and global solar radiation data and employs several indexes to compare the smoothing effect with various combining *** results show that combining wind and solar powers within a certain area can cause a fall of zero-power or very-full power ***,combining different resources improves smoothness in power output when compared with that from each individual ***,under hourly time scale,when the dispersion of sites is large enough,the smoothing effect of combining the dispersed wind power is very close to the combination of those two different ***,this complementary effect is much better than that of just combining solar energy resources.
