The need for storage in electricity systems is increasing because large amounts of variable solar and wind generation capacity are being deployed. About two thirds of net global annual power capacity additions are solar and wind. Pumped hydro energy storage (PHES) comprises about 96% of global storage power capacity and 99% of

Energy is transmitted via roof conductor rails in canopied stations and tunnels. In these sections, the energy storage systems are charged to enable the vehicle to cross subse-quent line sections that are without an overhead contact wire. To store the necessary drive energy, a hybrid energy store (HES) is used – a combination

Aiming at the severe problem of water scarcity and uneven distribution, many countries have adopted solutions such as inter-basin water diversion projects and cascade pumping stations (Wang et al. 2016; Liu et al. 2020).However, the long-term operation of these projects, especially the cascade pumping stations, generates huge
