Technical and economic feasibility survey for wind and photovoltaic hybrid renewable energy system. A case study in Neiva-Huila, Colombia

Abstract

This research presents a design and techno-economic assessment for implementation of wind & solar hybrid renewable energy system in Neiva city. The study performed an analysis of meteorological variables trend related, for a five years period (2010-2016) supplied by the Instituto de Hidrología, Meteorología y Estudios Ambientales de Colombia-IDEAM with the purpose to identify resources potential, beside of electrical requirements summary and energy cost for a node in the residential area. Sizing and evaluation were made by four architectures according to portion of each renewable source. For optimization and sensitive cases simulation were used the Hybrid Optimization Model for Multiple Energy Resources-HOMER software. The most reliable option was just for a photovoltaic solar source and no-available one the wind option due to the resources boundaries (wind speed less than 2 m/s). The results showed a major reliability from solar energy with an output power in 7475 kWh-year, cost of energy in 0,14 $USD/kWh and the less total cost in $1956 USD giving participation of 65% in daily consumption.
