Simulación de un sistema fotovoltaico conectado a red para abastecer la demanda eléctrica de una vivienda unifamiliar : Simulación de un sistema fotovoltaico conectado a red.

Abstract

The project aims to create a simplified and optimal guide for the design and simulation of grid-connected photovoltaic systems. For which, a dimensioning tool was developed based on the analytical method of the Center for Energy, Environmental and Technological Research CIEMAT, and under the Ecuadorian regulation 003/18 imposed by the Agency for the Regulation and Control of Energy and Non-Renewable Natural Resources ARCERNNR . This tool was developed through visual basic for application VBA, within the excel software interface, where all the steps of the previously mentioned method were considered, in addition to all the requirements of regulation 003/18 regarding electrical protections, obtaining a total of 6 forms that are oriented to the design of the photovoltaic system as such, 2 forms for the design of electrical protections and electrical conductors, and an additional form to generate a report of results. The latter being the space where all the information of the components selected in the design is summarized, from which an approximate cost is given for the physical implementation of the system. On the other hand, for the dimensioning of electrical conductors, the Ecuadorian construction standard NEC was used as a complement. The validation of results was carried out by means of a simulation in the PVsyst software, for which a solar panel and an on-grid inverter were used, with electrical characteristics very similar to those of the devices selected in the analytical design, in order to that the simulation had a high degree of reliability for the analysis of results.
