The CESS is an integrated system of cascade hydropower plants and pump stations, whose main function is to consume excess energy from renewables, while satisfying water and energy demands for the public. Essentially, the CESS belongs to a kind of pumped storage power station.
How can a cascade hydropower station be reconstructed?
It can be reconstructed based on the existing dam and powerhouse within cascade hydropower stations so that the cost is lower than the traditional pumping and storage station. In some studies, it is called the “large-scale cascade hydropower energy storage system” (LCHES) or “hydroattery” .
Can pumped storage power stations support a high-quality power supply?
Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir.
What is the eficiency of a cascade hydropower system?
The eficiency is defined as a ratio of reduced renewable energy curtailment to increased hydropower pro-duction, and it is calculated based on two scenarios (i.e., optimal oper-ations of the cascade hydropower system and CESS). A case study using China’s Longyangxia-Laxiwa CESS was conducted.
