Gestão de armazenamento de energia integrado com fontes renováveis e intermitentes

Abstract

This work address the configuration of energy storage integrated to intermittent renewable sources, especially photovoltaic systems, connected to the electricity distribution network. This is the result of the Research and Development Project, “Multimodal Electric Mobility Intelligent System (R&D) Applied in the Amazon Region (SIMA)”, developed at the Amazon Energy Efficiency Center (CEAMAZON), where there is a mini electric network with photovoltaic generation, diesel generation, electric vehicles charging stations, energy storage and coupling point with the CA network of the university city Prof. Dr. José da Silveira Netto, of Federal University of Pará. The mini electric network management is accomplished by a hybrid inverter associated with a load controller, capable of informing and managing the power that is being generated by the FV arrangements, the charging state of the battery bank, which also has its own management, through the BMS (Battery Management System); and the power being injected into the AC bus. With the case study, management strategies were defined through demand-side energy management, time shift, with a 55% reduction in the total cost of the 2022 annual bill for the CEAMAZON building. In addition, an economic feasibility analysis was presented through the tip load factor (FCp) with PDE 2032 VLP , arriving at a positive and justifiable result for application. Finally, a carbon exchange analysis arrived at a sustainability equivalent of 11 trees typical of the Amazon rainforest cultivated for the total emissions avoided in 2022 in the university city; and a carbon credit 298.43 tCO2, corresponding to R$ 131,902.4 for the carbon market.
