A new methodology for hybrid energy systems (HESs) was developed, namely the HY4RES model, tailored water sector, covering objective functions and grid or battery support using optimization algorithms in Solver, MATLAB, Python, with evolutionary methods. HOMER is used microgrids allows comparison HY4RES, newly developed model. Both models demonstrated flexibility optimizing renewable solutions. This study analyzed an irrigation system 3000 m3/ha (without renewables (Base case) Proposed system—with PV solar pumped-hydropower storage to maximize cash flow over 25 years). Case 1—3000 presented benefits due supplying ~87% of energy, reducing dependency ~13%. Pumped-hydropower (PHS) charges excess ensuring 24 h irrigation. Sensitivity analyses 2—1000—and 3—6000 m3/ha—highlighted advantages limitations water-energy management optimization. 2 most economical lower needs noteworthy sales (~73.4%) no need grid. 3 led increased operating costs relying heavily on (61%), providing only 39%. PHS significantly lowered enhanced by selling

This research developed smart integrated hybrid renewable systems for small energy communities and applied them to a real system achieve self-sufficiency promote sustainable decentralized generation. It compares stand-alone (SA) grid-connected (GC) configurations using optimized mathematical model data-driven optimization, with economic analysis of various combinations (PV, Wind, PHS, BESS, Grid) search the optimal solution. Four cases were developed: two (SA1: PV + Wind SA2: PHS BESS) (GC1: Grid, GC2: Grid). GC2 shows most economical stable cash flow (−€123.2 annually), low CO2 costs (€367.2), 91.7% grid independence, requiring 125 kW installed power. While GC options had lower initial investments (between €157k €205k), SA provided levelized (LCOE) ranging from €0.039 €0.044/kWh. The integration pumped hydropower storage enhances supporting peak loads up days capacity 2.17 MWh.

Renewable energy sources like solar and wind face an insurmountable obstacle in the form of environmental change-induced discontinuity instability. Since hydropower is quick to respond doesn't cost much alter, it was a common choice for electric system correction. A cascade (CHP) station compensates hydro power-solar-wind that we present this study, which considers several long-term goals. Among model's objectives optimization power system's annual total generation while simultaneously minimizing output variations. As prerequisite optimizing hydropower, model first determines Photovoltaic (PV) power, then feeds those numbers into grid. In order obtain set solutions has been proposed, suggest enhanced non-dominated sorting whale algorithm (NSWOA). According findings, decision-makers have access plethora options optimal selection through revised NSWOA, hydropower's superior modifying capabilities more than compensate PV power's deficiencies.
