Controle flexível de geradores distribuídos de energia utilizando conceitos de indústria 4.0

Abstract

Industry can be considered the subsistence core of a capitalist society, and it is followed by a constant search for new technologies that can improve the productive chain. However, when speaking of industry, it is impossible not to talk about energy, because there is a great dependency among these factors, and consequently the search for improvements on energy production is also constant. These researches have opened space for the distributed generation of energy, which has significantly complemented the centralized generation. In this sense, this study aimed to develop a decentralized architecture for control of electric energy, making use of Industry 4.0 concepts. The system has been divided into three levels, local sub-central (generator), local central (microrgrid) and global central (Web). By using Supervisory Control Theory, plants have been modeled for the generator and microgrid components, as well as defined and modeled control specifications to control these plants. Simulations have been done to test the models, as well as the controller synthesis for these models. Then, the translation of the models in programming language was carried out and a firmware was developed for each layer of control, integrating it with its respective hardware. A multi-level communication between the two lower layers was developed and tests of the implemented system were performed for validation.
