Avaliação econômica da utilização de fontes alternativas de energia elétrica utilizando o software Homer Pro

Abstract

Distributed generation has gained more and more space in the Brazilian electrical system. This generation is located near the load centers, connected to the distribution system, small or medium size and not dispatched by ONS (National System Operator). Photovoltaic and Wind Energy are the sources of distributed generation on the rise. These sources use panels to generate electric energy through sunlight, and wind turbines to generate energy through the conversion of kinetic energy from the wind. At times when there is no solar irradiation, a storage system of the energy generated during the sun and wind schedules is necessary. Therefore, the objective of this work is to economically analyze the implementation of a system of alternative generation and storage of electric energy. Firstly, a pattern of battery quantity will be modeled and defined, where it will be possible to visualize the storage capacity, load rates. Faced with constant changes in electricity tariffs, the study of the impact of the use of alternative energy sources and storage systems, using batteries, is a very economically advantageous option. That said, this study aims to support the alternative of distributed generation, adding parameters of energy continuity with the use of storage elements in the system, in order to verify the economic viability of the implementation of these technologies. The results obtained were that the higher the load demanded by the customer, the insertion of the batteries becomes attractive and profitable for analysis.
