Technical and Economic Analysis for the Implementation of a Hybrid Solar Photovoltaic and Wind Distributed Generation System at the Nuclear Engineering Center of the Institute for Energy and Nuclear Research

Objective: To analyze the technical and economic feasibility of a hybrid distributed generation system combining solar photovoltaic and wind energy at the Nuclear Engineering Center (CEN) of the Institute for Energy and Nuclear Research (IPEN). Theoretical Framework: The study is grounded in distributed generation, photovoltaic solar energy, wind energy, grid-connected hybrid systems, and simple payback. Method: A quantitative case study used installed-load and annual-consumption data, solar irradiation records, and a Weibull distribution for local winds. The subsystems were sized and two scenarios compared. Results and Discussion: Wind generation would supply 3.70% of demand in Scenario 1 and 3.52% in Scenario 2, with photovoltaics supplying most of the load. Estimated investments were BRL 192,490.25 and BRL 188,436.61, and both scenarios yielded estimated annual savings of BRL 48,055.72. Research Implications: The model supports decisions in institutions with similar energy profiles by integrating resource availability, costs, and performance. Originality/Value: The research provides an applied and replicable assessment of solar-wind complementarity in a Brazilian nuclear research institution.
