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.

Where is the complementarity of wind and solar resources in China?

It can be seen from the spatial distribution that wind and solar resource complementarity is relatively high in northwest, northeast, and central China, while the complementarity in the southwest and southern areas of China is relatively low.

What is China's power generation potential from wind-solar-hydro power resources?

China's total annual power generation potential from wind-solar-hydro power resources is 17.57 PWh after complementary optimization using the MOO model based on NSGA II, which is 4.2% less than the 18.34 PWh without considering complementary optimization.

What is LM-complementarity between wind and solar power?

The LM-complementarity between wind and solar power is superior to that between wind or solar power generated in different regions. The hourly load demand can be effectively met by the LM-complementarity between wind and solar power.

Does complementarity support integration of wind and solar resources?

Monforti et al. assessed the complementarity between wind and solar resources in Italy through Pearson correlation analysis and found that their complementarity can favourably support their integration into the energy system. Jurasz et al. simulated the operation of wind-solar HES for 86 locations in Poland.

Can LM complementarity balance renewable power generation and load demand?

However, it is hard to balance renewable power generation and load demand on the daily time scale by the LM-complementarity. Compared with the complementarity for power smoothing defined in previous studies, the instability and peak-to-valley differences of the net-load demand can be effectively reduced by LM-complementarity.
