This paper proposes a hybrid power system(HPS) that integrates Pumped-Storage Hydroelectricity(PSH) with Floating Photovoltaic (PV) power generation, utilizing the underused infrastructure of a agriculture reservoirs as a mechanical Energy Storage System(ESS). We quantitatively applied this HPS model to an operational reservoir to evaluate its technical and economic viability. The analysis, conducted using Electro-Magnetic Transients Program (EMTP) simulations, demonstrates that the system effectively maintains a stable grid frequency of 60 Hz by mitigating the intermittency of PV power through real-time MPPT control and pumped-storage synergy.
Initial economic assessments yielded a Benefit-Cost Ratio (BCR) of 0.68, indicating low feasibility for the baseline model. However, by expanding the floating PV capacity fourfold to leverage economies of scale and maximize the utilization of the available water surface, the BCR improved to 1.1. This enhancement is attributed to the distribution of fixed costs over a larger generation capacity and the elimination of expensive chemical battery requirements, as the water body itself serves as the storage medium. These findings suggest that the proposed HPS model can serve as an efficient decentralized power solution to support carbon neutrality goals.
