Study of electrification system based on solar photovoltaic generation to supply riverside buildings

Abstract

This work focuses on the design and computational simulation of solar-based electrification systems aimed at supplying buildings not connected to the conventional electrical grid in the Urubuéua Cabeceira location, within the municipality of Abaetetuba, in the state of Pará, Brazil. The systems designed for these buildings have the following specifications: a 5.28 kWp photovoltaic generator, three bidirectional inverters, each with a 5 kW capacity, and a 53.32 kWh battery bank. Following the sizing, the systems are simulated using the PV*SOL computer program. In these simulations, three operational scenarios are considered. The first scenario involves a 50% increase in household consumption on weekends; the second deals with a 15% rise in workshop consumption during October; the third scenario explores the non-operation of the workshop system, resulting in a system without energy generation. Regarding the results achieved, the system simulations have been particularly noteworthy, delivering excellent outcomes that align well with the intended objectives. The flexibility of the interconnected systems enables efficient energy exchange among sources.
