The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.
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.
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).
