Optimization Modeling of the Capacity of Pumped Storage Power Stations Amidst a High Proportion of New Energy Sources

In the context of a growing share of new energy sources, the traditional dispatch optimization methods for pumped storage power stations, including empirical operations based on daily pumping balance, are becoming inadequate for maximizing resource utilization. This paper introduces an innovative capacity optimization model for pumped storage stations, tailored for environments with a high proportion of new energy. The model uniquely focuses on optimizing the daily starting and ending storage capacities of pumped storage plants on a rolling basis. The validity and practicality of this optimization model are demonstrated through specific arithmetic example verifications.
