4 FAQs about Wind and solar power generation around the two hydropower stations

Will hydropower be a major source of energy in 2060?

These provinces rely mainly on hydropower to provide dispatchable power. In the stage of 2030, hydropower can provide strong support for the power balance, so the additional demand for energy storage is relatively small. However, by 2060, the significant increase in wind and solar power capacity will lead to a significant gap in system flexibility.

What is the key to a hydro-wind-solar hybrid system?

The key to the power generation of a hydro-wind-solar complementary system lies in the uncertainty of wind and solar output. For the risk management of grid-connected operation of a hybrid system, the power prediction error of wind and solar power is considered by reliability or the risk index.

Can hydropower support large-scale wind and solar power?

These studies focus mainly on a certain aspect of variable renewable power sources under extreme weather conditions, but the role of hydropower in supporting large-scale wind and solar power has received little attention. In fact, numerous large hydropower stations in a hybrid system can play a critical role as flexible power sources.

Can hydro-wind-solar hybrid systems absorb new energy?

One of the core tasks of the short-term operation of the hydro-wind-solar hybrid system is how to use the flexible regulation ability of hydropower to stabilize the intermittence and volatility of the new energy output. Therefore, it is necessary to carry out quantitative research on the flexibility needed to absorb new energy.
