Technical FAQs 4

Do wind and solar power outputs in China have a temporal complementarity?

Overall, wind and solar power outputs in various provinces of China exhibit strong temporal complementarity. Although there is no negative correlation in Tibet, Yunnan, and Sichuan, wind-solar power joint output can smooth the fluctuations of solar or wind power outputs.

Does spatial and temporal complementarity of wind and solar power match electricity demand?

Therefore, analyzing the spatial and temporal complementarity of wind and solar power and their matching characteristics with electricity demand is of great significance for constructing reliable and cost-effective high-proportion renewable energy systems.

Are wind-wind power and solar-solar power spatial complementarity related?

The correlation and fluctuation index results of wind-wind power and solar-solar power spatial complementarity between different provinces in summer. (a) and (b) are Kendall’s correlation coefficients of wind-wind power spatial complementarity and solar-solar power spatial complementarity, respectively.

Which provinces have a temporal complementarity between wind and solar power?

At the annual scale, except for Tibet, Yunnan, and Sichuan, all other provinces exhibit a temporal complementary relationship between wind and solar power outputs (with negative Kendall’s correlation coefficients). Provinces with richer wind and solar resources demonstrate stronger temporal complementarity.
