Effect of wind and solar energy high current ring network cabinet

Why are wind and solar power penetration rates so low in China?

However, the penetration rates of wind and solar power in China remain suboptimal because of the inherent instability of energy sources , resulting in a high curtailment rate and resource utilization efficiency that fall significantly below international benchmarks , which is a major obstacle in the context of carbon neutrality .

Why are wind and solar energy instabilities affecting grid load management?

The instabilities of wind and solar energy, including intermittency and variability, pose significant challenges to power scheduling and grid load management , leading to a reduction in their availability by more than 10 % .

Can wind energy compensate for the absence of solar energy?

At night, wind energy can compensate for the absence of solar energy, covering 20%–60 % of the time. (4) Hybrid wind-solar complementary development can enhance stability by approximately 45 % compared to relying on a single solar energy source.

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

Researchers have observed significant complementarity between wind and solar energy in China by utilizing indicators such as correlation coefficients . This complementarity is most evident at the hourly to daily scales, particularly in regions such as Xinjiang and the Hexi Corridor .

Can hybrid wind-solar power reduce the instability of wind and solar power?

The instability of wind and solar power hinders their penetration into electrical transmission networks. Hybrid wind-solar power generation can mitigate the instability of wind or solar power. However, research on complementary methods and the temporal distribution of wind and solar energies remains insufficient.

Should wind and solar energy ratios be integrated in complementary development?

The optimal blending of wind and solar energy ratios in complementary development can significantly reduce the instability of wind and solar energies, thus avoiding investment risks and resource wastage. Nevertheless, current research predominantly concentrates on optimizing wind and solar ratios within integrated energy systems.
