Simulación de un sistema de generación fotovoltaico aislado para zonas rurales del Ecuador

Abstract

Renewable technologies are a form of modern, clean energy with very low environmental impact. They can become a practical option for electrification, especially for rural areas in Ecuador, where limited access to electricity limits the possibilities of development in these areas. Solar energy is the resource used by isolated photovoltaic generation systems, which are used exclusively for rural areas because the installation of the electrification grid is expensive or technically difficult. For this reason, an isolated photovoltaic system has been developed in the Matlab/Simulink environment, which is made up of an array of photovoltaic modules, a load regulator, a battery system, and a single-phase inverter, which together will make it possible to know the behavior of the generation of electrical energy through photovoltaic solar energy. In addition, a maximum power point tracking (MPPT) algorithm was developed to obtain the peak power of the photovoltaic array and a discrete integral proportional control was incorporated for the charging and discharging of the batteries. Furthermore, a sizing tool was designed and developed through Macros and Visual Basic of Excel, which facilitated the enter of the different parameters and the immediate obtaining of the results.
