Viabilidade técnica e econômica para implantação de armazenamento para consumidores industriais do grupo A4

Abstract

The industries seek to make their production process more and more economical and sustainable, thinking about this scenario, energy storage appears as an alternative for use at peak hours, which can be used in conjunction with technologies for distributed generation of photovoltaic solar energy. The forms of energy storage are diverse, but the use of electrochemical batteries, lithium ion and lead-acid, is highlighted for their characteristics of flexibility, versatility, quick installation, cost. In this monograph the application of these technologies in the Brazilian pricing environment will be discussed, comparing their application in the RGE Sul and Equatorial PA concessionaires. The economic analysis was based on economic indicators commonly used in projects. The case study of three medium voltage consumers will be applied in the plants of the following industries: Soprano Electrical Materials unit in Caxias do Sul, Multinjet Tecnologia em Metaização LTDA and Indústria Metalúrgica Dalgian LTDA, through analysis of the invoice, the storage and photovoltaic projects were dimensioned, It was observed that the smaller the storage project the shorter the turnaround time for the project, as well as the greater its profitability. The tariff environment also influences economic results, the higher the tariff, the lower the payback and the greater the profitability. Li-ion applications tend to have a higher initial cost and a lower accumulate cost over the lifetime of the project, but the kWh cost calculated using the LCOE is also higher in these cases. The main difficulty for the development in Brazil is the lack of regulation for hybrid inverters. [resumo fornecido pelo autor]
