The widespread use of green energy sources creates a significant demand for storage. Hybrid floating photovoltaic (FPV) and pumped hydro storage (PHS) represent one the most dependable cost-effective solutions, which uses PV system on water body combined with pair lakes different heights. This study focuses load side as well PHS capacity factor aims to lower cost (COE) by raising factor. Since building requires upfront investment, doing so will also COE enable acquisition large-scale power production, guarantee access in large cities. To simulate FPV-PHS system, multi-objective genetic algorithm (MOGA) is employed. Sufficient management prerequisite achieving reliability best possible hybrid design implementation. Considering 60-year lifespan, net present (NPC) analysis shows that, out all communities evaluated, has lowest NPC COE. For optimal configuration (FPV (Block A) 105 MW, 80 FPV B) 357 current hydropower plant), expected costs implementing (HRS) at chosen location are $44,737,613 $40/MWh, respectively. existing spans 4.65 km2 lowers evaporation fraction 17,279,400 m3. reduces annual CO2 emissions 581,830 tons. Our research reveals that pump offers more steady clean electricity, implying great significance grid infrastructure.
