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.
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.
Scenario III was used to calculate energy production potential of the cascade hydropower plants, and the pump station was assumed to shut down. In this scenario, operating rule curves and power output decision in each zone of the Longyanxia were optimized using MOCS, with objective functions as shown in Eqs. (14), (15) and (17).
In view of these, a larger scale CESS consisting of three or more cascade hydropower plants would be considered to further investigate its operation mechanism. Meanwhile, a long- and short-term nested operation model could be constructed to refine operating rules of the CESS. Long Cheng: Data curation, Conceptualization.
However, despite the progress in policies and technologies for promoting the renewable energy integration, there still exists an urgent need to develop large-scale and long-duration energy storage facilities, which is driven by the rapid expansion of wind and solar en-ergy sources.
