Run-of-the-River Hydro-PV Battery Hybrid System as an Energy Supplier for Local Loads

Hybrid hydro energy systems are usually analysed with pumped storage systems, which can facilitate accumulation from other sources. Despite the lack of water storage, run-of-the-river hydropower plants also attractive for hybrid owing to their low investment cost, short construction time, and small environmental impact. In this study, a system that contains power (SHPs), PV batteries serve local loads is examined. Low-power low-head schemes use variable-speed operation considered. The novelty study proposal dedicated steady-state model plant suitable production analysis under different hydrological conditions. presented calculations based on real SHP 150 kW capacity have shown simplified method result in 43% overestimation produced energy. Moreover, one-year using river flow data showed averaging period has significant influence balance results. deficiency surplus be underestimated by approximately 25% increasing time day month.
