GONZALEZ-MONTOYA, Daniel et al. Technical-economic feasibility analysis of micro grids integrating fuel cells in non-interconnected zones in Colombia. TecnoL. [online]. 2018, vol.21, n.43, pp.71-89. ISSN 0123-7799.  https://doi.org/10.22430/22565337.1057.

The sustainable power solutions provided to non-interconnected zones should be based on the renewable energy resources available in each area. This presents a challenge for the techno-economic feasibility of alternative solutions through micro grids. The objective of this work is to analyze, using HOMER software, the techno-economic impact of introducing fuel cells on cost reduction during the lifetime of micro grids in non-interconnected zones. Such impact is evaluated in the technical design of the micro grid as Present Value and Levelized Cost of Electricity ($/kWh). The analysis considers the calculation of the demand of a generic village, the size and cost of the technologies that constitute the micro grid to satisfy the demand, and the availability of solar and wind power in two areas located at different latitudes in Colombia. In addition, the effect of introducing fuel cells into the energy mix was examined. Finally, the advantages were highlighted by comparing each case with traditional generation alternatives based on diesel consumption.
