Bottlenecks in solar power generation systems

What causes idle wind and solar capacity in China?

Therefore, the fundamental reason for idle wind and solar capacity is the failure to ensure a real-time balance between the supply of and demand for energy in the power system. In the following sections, we analyze the bottlenecks that restrict the development of renewable energy in China, based on actual conditions. 2.1.

Why is solar power a problem?

However, the root causes of the problem are a mismatch between the development of wind power and solar power and the current power system, immature technology, difficulty in absorbing wind and solar power across regions, and a lack of large-scale capability for absorbing wind and solar power on the demand side.

Why is Xinjiang reducing wind and solar power?

However, in 2018, the decrease in wind and solar power in Xinjiang, Gansu, and Inner Mongolia exceeded 3 × 10 10 kW⋅h, accounting for more than 90% of their total idle capacity in the country, indicating that idle capacity is a serious issue in some regions. Loose energy supply is one of the reasons for idle wind and solar power in recent years.

Why are Chinese thermal power plants better than Germany?

At present, Chinese plants have much shallower peak-shaving capability than plants in Denmark and Germany, and the rapid climbing capability of peak-load regulation is only half that of Germany. Moreover, it is basically impossible to achieve a start–stop cycle. Second, it is vital to improve thermal power flexibility.
