Technical-economic analysis of a grid-connected photovoltaic system

Resumen

This article presents the technical-economic feasibility of a distributed energy system connected to the grid or micro grid for the Recintos Zapallo, San Mateo parish, Esmeraldas Province. Having distributed generation seeks to minimize power losses by having generation from the load point. The work begins by collecting monthly data of the electrical loads of the Zapallo compound, climatic data and associated monetary data with the objective of investigating a feasibility study of the renewable energy supply system. Different scenarios are developed according to the needs of the project and the scenarios were modeled using HOMER software. The study concludes with a direct comparison of economic feasibility, renewable energy fraction and emission between all aspects of the system for a suitable sustainable solution. This study is useful for distribution companies to have an additional element of judgment to minimize power losses in the network, as well as to consider building island circuits to optimize distribution costs in rural locations.
