Are wind power and solar PV power potential complementary?

The assessment results of temporal volatility of wind power and solar PV power potential in different regions of China show that they can be well complementary at different time scales.

Can wind-solar-hydro complementarity improve China's future power system stability?

Wind-solar-hydro complementary potential shows great temporal and spatial variation. Renewable complementarity can improve China's future power system stability. In the context of carbon neutrality, renewable energy, especially wind power, solar PV and hydropower, will become the most important power sources in the future low-carbon power system.

Does wind power and solar PV have a decarbonization pathway?

Since wind power and solar PV are specifically intermittent and space-heterogeneity, an assessment of renewable energy potential considering the variability of wind power and solar PV with high temporal resolution in different regions will facilitate more accurate identification of the decarbonization pathway of power system.

Can power complementarities solve the problem of localized resource shortages?

Therefore, if the provinces within the same grid region are allowed to be dispatched flexibly and further complement each other, which is not possible at the intra-provincial scale, and to a certain extent solves the problem of localized resource shortages faced by power complementarities. Fig. 6.

Which countries have a curtailment of wind power & solar PV?

For example, China's curtailment of wind power and solar PV has occurred in the northwest, with a 14.0% wind power curtailment rate (6.61 billion kWh) , and a 7.4% solar PV curtailment rate (340 million kWh) in Xinjiang in 2019 .
