Análise de viabilidade econômica frente às alternativas de conexão em cenários de inversão de fluxo de potência: um estudo de caso

Abstract

This paper aims to assess the economic feasibility of two connection alternatives proposed by ANEEL's Resolution 1,000/2021, in relation to the power flow inversion in a commercial consumer unit, located in the CPFL Paulista concession area. The analyzed scenarios include a 75 kW solar photovoltaic project project participating in the Electric Power Compensation System (SCEE) and the Zero Grid model, in which all generated energy must be consumed simultaneously. The methodology involves processing the installation's consumption data, photovoltaic generation simulations, and the evaluation of economic feasibility indicators such as the Internal Rate of Return (IRR), Net Present Value (NPV), and Discounted Payback. The results show that although the Zero Grid project requires a larger initial investment and has a slower return, it generates a higher total value over the evaluated period. The SCEE project, on the other hand, presents a faster return but a lower total value. The conclusions highlight the importance of a careful analysis for investment decisions, considering both the payback period and the total value generated
