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.
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.

Energy storage plays an important role for electrical systems, allowing for demand – supply mismatch balancing, peak shaving, fre-quency regulation, damping energy oscillations, and improving power quality and supply reliability .
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).
