Análise da viabilidade de gerenciamento de energia elétrica no CETENS

Abstract

This paper presents an analysis on the application of Distributed Energy Resources (RED) for better energy management in the Center for Science and Technology in Energy and Sustainability — CETENS considering Distributed Generation (GD), Energy Storage, Demand Response (RD ) and Energy Efficiency. The generation distributed with the photovoltaic solar source, due to being the most used in Brazil, energy storage through lithium batteries, demand response and energy efficiency with the white tariff. As a strategy of distributed energy resources, the peak reduction technique was used with energy storage in batteries, aiming at handling consumption at peak hours. In addition, the photovoltaic system connected to the grid has the function of supplying the batteries at times of higher incidence of sunlight. Thus, the proposed methodology considers the load curve of CETENS lighting during working hours in accordance with ORIENTATION Normative n. 01/2019, energy tariffs, natural resource, photovoltaic systems for distributed generation and batteries for energy storage. As a simulation tool, the System Advisor Model (SAM) software was used, being a technical-economic software model, whose purpose is to facilitate the analysis of decisions in the application of distributed energy resources, exploring distributed generation, energy storage and white tariff. The results showed that distributed energy resources contributed to the reduction of peak load at intermediate and peak hours with the function of energy storage and distributed generation, as well as to the reduction of the bill, which enabled the use of the white tariff.
