Promote wind power and photovoltaic power generation

How to promote a high-quality development of wind and solar power?

To comprehensively promote large-scale and high-quality development of wind and solar power, give priority to local and nearby development and utilization, speed up the construction of decentralized wind and distributed PV power in load centers and surrounding areas, and promote the application of low-wind wind power technologies.

What are the development modes for wind and PV power systems?

In terms of wind and PV power development modes: centralized and decentralized development, land and sea development, nearby and external development, multi-energy complementation, single and multi-scene development will be the direction of the future. Table 1. Relevant policies for integrated development in solar and wind energy systems in China.

How will solar PV & wind impact global electricity generation?

The share of solar PV and wind in global electricity generation is forecast to double to 25% in 2028 in our main case. This rapid expansion in the next five years will have implications for power systems worldwide.

How does weather affect solar PV & wind energy generation?

It is well known that solar PV and wind energy generation are heavily influenced by weather fluctuation, which yields strong variability at various time scales. Understanding the variability of renewable energy is vital for coordinating compensatory energy sources and storage in order to secure a stable energy supply 66, 67.

What is the power-use efficiency of PV and wind power plants?

By considering the flexible power load with UHV and energy storage, the power-use efficiency for PV and wind power plants is estimated when the electrification rate in 2060 increases from 0 to 20%, 40%, 60%, 80% and 100% (a) and the power generation by other renewables in 2060 increases from 0 to 2, 4, 6, 8 and 10 PWh year −1 (b).

What are the benefits of solar power versus wind power?

However, such systems mitigate the intermittency issues inherent to individual renewable sources, enhancing the overall reliability and stability of energy generation. Solar power exhibits peak output during daylight hours, while wind power can be harnessed even during periods of reduced solar availability .
