Simulación de un sistema fotovoltaico aislado para abastecer la demanda de una vivienda rural : Simulación de un sistema fotovoltaico aislado.

Abstract

The degree project: "Simulation of an isolated photovoltaic system to supply the demand of a rural house" was created in order to share a technical tool with those people interested in the dimensioning of isolated photovoltaic systems. To do this, a study of electrical loads (appliances) was carried out in a single-family home located in the parish of San Antonio de Pichincha in Quito, Ecuador and the analytical method of the Center for Energy, Environmental and Technological Research (CIEMAT) of Madrid was used for the dimensioning of the photovoltaic system that would supply the electrical demand in this home. Consequently, the Excel office automation package and the Visual Basic for Applications (VBA) software were used for the design of the isolated photovoltaic system sizing tool, which consists of nine windows that size the different components of the system: in the first window a study of the electrical loads that a house has is carried out while in the second window the DC voltage of the photovoltaic system is determined. In the third, fourth, fifth and sixth windows, equipment is sized such as: number of solar panels, charge controllers, inverters and batteries, respectively. In the seventh and eighth windows, the cables and fuses of the system are sized based on the electrical currents handled by the previously mentioned equipment, and in the ninth window, a report on the sized isolated system is shown, which includes estimated installation costs. Finally, the operation of the sizing tool was validated with the PVsyst simulation software.
