Ferramenta de otimização dos parâmetros contratuais das contas de energia elétrica de unidades consumidoras do governo do estado

Abstract

Today's society is largely dependent on electricity, and its growth is even restricted to the availability of this resource. To ensure the health of the nation in different aspects, it is important that the electrical system is optimized in order to minimize costs and provide resources for its expansion. Aiming at this, this work brings a methodological suggestion to reduce costs from the billing of consumer units of subgroups A3 and A4, belonging to the Government of the State of Ceará. The study was based on contractual variables, such as contracted demand and tariff modality, in order to obtain savings without the need for investments. Following the regulations provided for in Normative Resolution No. 1000 of ANEEL (National Electric Energy Agency), of December 7, 2021 and using Big-M formulations, the current billing methodology was modeled and a Mixed Integer Programming (MIP). The implementation and solution of the model were done through the Python-MIP library. Finally, with a hit rate of 99.4%, the algorithm was able to find a cost reduction potential of more than 50 million reais, corresponding to a savings of 27.67% of total costs.
