How can wind and solar energy be optimized for Integrated Energy Systems?

Numerous researchers have focused on optimizing the installed capacities of wind and solar energy in integrated energy systems . Adjusting the wind and solar ratios can significantly reduce the required storage capacity of the system, thereby ensuring a more stable power supply .

What is hybrid wind-solar power?

Wind-solar hybrid power ensures continuous renewable supply during daytime hours. Adjusting wind and solar proportions enhances their complementary strength. 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.

Can a wind-solar hybrid power supply maintain a continuous power supply?

The results show that the seven renewable energy bases in China mainland can maintain a continuous power supply during the daytime using a wind-solar hybrid complementary power generation (Fig. 5).

Can a base maintain a consistent power supply using wind & solar energy?

Approximately eight daylight hours (9 a.m.-5 PM) exhibited a WSS index reaching 100 %, WSB index surpassing 50 %, and a nighttime WCS index ranging from 45 % to 50 %. This indicates that these bases can maintain a consistent power supply using wind and solar energies throughout the day.

How stable is solar power in China?

Notably, in northwestern China, including Xinjiang and the Hexi Corridor, the most significant stability improvement occurred when the proportion of solar power capacity was approximately 55%–60 %, resulting in an IFS value of 0.35.

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 .
