What are the characteristics of wind and solar energy potential in China?

Wind and solar energy potential show similar characteristics in most parts of China, especially in the northern and southern parts of China. A few regions exhibit complementary characteristics, including the southeastern coastal areas and northeastern regions.

Is there a correlation between wind and solar energy in China?

By calculating the Kendall rank correlation coefficient between wind and solar energy in China, the study mapped the spatial distribution of wind-solar energy complementarity. Han et al. proposed a complementary evaluation framework for wind-solar-hydro multi-energy systems based on multi-criteria assessment and K-means clustering algorithms.

Are wind and solar energy complementary?

Given that wind and solar energy are distinct forms of energy within the same physical field and are typically developed simultaneously in clean energy bases, it is essential to comprehensively assess the variation patterns of complementarity metrics under different climate change scenarios.

How to measure wind-solar complementarity in China?

The seasonal and monthly wind-solar complementarity of China can be quantified through the calculation of WPD and PV pot, as depicted in Fig. 9, Fig. 10. It should be noted that Fig. 9, Fig. 10 are based on Spearman's rank correlation coefficients of WPD and PV pot, which are determined by the classification standards in Table 3. Fig. 9.
