Hybrid architecture for financial assessment of wind-solar power system based on weather conditions in Neiva city

Abstract

The increase in population is an increase in the consumption of energy and basic resources for subsistence. One of the services of vital importance for the well-being as for the development of activities is the electrical fluid. There are several sources to generate electricity such as dams, wind or sun; the latter is little studied in our region. The present study presents an analysis of the behavior of meteorological variables, a synthesis of the electrical requirement and energy costs for three research nodes in the residential area of the city of Neiva. The methodology includes the analysis for four architectures. The technical evaluation consists of the installed capacity of the system for the solar and wind component. For the economic evaluation, models are used such as the level of energy cost, the net present value, the period of recovery of the investment and the internal rate of return. A scenario with tax benefits of Law 1715 is presented. The HOMER software is LPSP and LCE evaluation. Viability is obtained for a single sequence with photovoltaic modules, making the wind impossible by the new speeds of the lower ones at 2 m / s. The results present a greater reliability for a photovoltaic source system with an electric power generated per year 7475 kWh, an energy cost lower than 0.14 $ USD / kWh, as well as the total low cost in $ 1956 USD generating participation in the 65% daily consumption.
