claimStorage technologies suitable for Combined Flow Power Systems (CFPS) include lithium-ion batteries, flow batteries, pumped hydro storage, compressed air energy storage, and thermal energy storage.

procedureHydroelectric pumped storage generates electricity by moving water from a lower dam to an upper dam during off-peak loads, and returning the water to the lower dam during peak loads to spin turbines.

referenceMa et al. (2015) developed a model for a pumped storage-based independent photovoltaic power generation system and conducted a techno-economic analysis, published in Applied Energy.

claimCurrent energy storage solutions include battery banks, supercapacitor power storage, hydroelectric pumped storage, hydrogen power storage, compressed air power storage, flywheel power storage, liquid air power storage, and stack blocks.

measurementXu et al. determined that an optimal photovoltaic-air current farm with pumped storage in Xiaojin, Sichuan, China, reduced electricity costs by 32.8% and 45.0% respectively, with a 5% Loss of Power Supply Probability (LPSP) model achieving the lowest power cost of $0.091/kWh.
