The intermittency and variability of various renewable energy resources, such as wind power and photovoltaic solar energy, can overcome with the use of these resources in conjunction with energy storage devices. The energy storage as hydraulic power, so before energy conversion, can guarantee high efficiency to the storage process. This study aims to identify the technical and economic feasibility of using wind power and PV modules in conjunction with a reversible hydroelectric power plant installed in Aparados da Serra, in the south of the Serra Geral, a geological structure in southern Brazil that allows topographical height differences of approximately 600 m. In this work, specifically, a hydropower plant installed at Linha Sete with 610 kW and at 400 m height. This study explores the feasibility of this pumped storage plant operating in conjunction with existing wind turbines and PV modules installed on the surface of reservoirs. The work is based on simulations and optimization performed with well-known software HOMER. The results indicate that a group of 10-50 2-MW wind turbines may have an increased capacity factor from usual 0.34 to values between 0.50 and 0.60. The results also relate the power capacity and costs per kW installed for PV modules to be feasible. This work also indicates useful conclusions in the design process and implementation of the hybrid system under study.
