Estudo de viabilidade técnica e econômica: sistema fotovoltaico no ambiente de simulação HOMER®.

Abstract

This research aims to analyse a distributed generation model, applied to photovoltaic (PV) energy, with Homer simulation environment, and thus identified the economic viability for such architecture. It consists of a case study, from a residential profile load connected to a PV system and electrical grid (SFvCR), over the period of 25 years and located in the city of Campina Grande – PB. In addition, the components were dimensioned by Pinho and Galdinho (2014), where the proposed requirements respect as operating conditions. The results were organized and analysed, firstly, the electric study of the SFvCR such as the consumption and production of energy in monthly average values, and finally an economic analysis with formulation of annual cash flow with discounted values for a real rate, where includes inflation rate without cost of capital. Futher, the financial return of the SFvCR was estimated from accounting only the load connected to the electrical grid. In this way, it hopes this research contributes to increase the study of photovoltaic generation and as opportunities offered by the software Homer.
