Qinghai fills gaps in water-light complementary technologies in China

A few days ago, the major scientific and technological project of Qinghai Province, "Research and demonstration of large-scale hydro-complementary key technologies," passed the acceptance test of the National Photovoltaic Equipment Engineering Technology Research Center and other expert groups, filling the gaps in the domestic large-scale water-solar complementary key technologies, and its achievements have reached international advanced level. Level.

The project relies on Qinghai's abundant solar energy resources and unique hydropower resources to carry out research and demonstration of 320 megawatts of water-to-optic complementary technologies at the Longyangxia hydropower station, the world's largest hydro-optic hybrid power station, and converts photovoltaic power to stable, high-quality power. Improve the quality of photovoltaic power generation and realize the functions of rapid compensation for hydropower and photovoltaic power generation. At the same time, reducing the power system to absorb the rotating reserve capacity needed for independent photovoltaic power generation will increase the capacity of the power station's peak shaving and frequency adjustment without affecting the power generation efficiency of the hydropower station, so as to achieve the goal of not discarding light and not abandoning the water.
