Abstract
The aim of this work is size and analyze the techno-economic viability of an on-grid PV-wind hybrid system located in a rural settlement. HOMER Grid software was used, which allows the system modeling and economic optimization based on local solar irradiation and wind speed, costs of components and the system load curve. The locality chosen was the rural settlement Santo Antônio, located in the district of Touros, in the interior of the state of Rio Grande do Norte. After the simulations, comparisons were made among three systems: wind-solar hybrid, solar and wind. The results showed that, among the three systems, the hybrid stands out as the lowest configuration cost between the systems, totaling an NPC (Net Present Cost) of R$ 245,482 over a 25 years project lifetime. In addition, the COE (Levelized Cost of Energy) of the hybrid system was the lower among the systems and also in relation to energy tariff, with a cost of 0.226 R$/kWh. Thus, it can be concluded that the on-grid system is the viable solution to the proposed systems.
