Avaliação dos Benefícios da Operação Colaborativa de Microrredes

Abstract

The demand for electrical energy has been rising due to population growth and the advent of new technologies that need a constant and reliable energy supply. Concurren- tly, increased industrial activity in recent years has significantly impacted atmospheric pollution levels, prompting concerns among nations and regulatory bodies. The intro- duction of renewable energy sources, along with advances in power electronics, has enabled the utilization of distributed energy resources close to consumption points, leading to the concept of microgrids. These systems not only generate energy in an environmentally friendly manner but also enhance the reliability and resilience of the electrical grid through their capacity for islanded operation. Microgrids are foundatio- nal to smart grids and are crucial in the energy transition, transforming consumers into proactive participants, lowering costs, and improving the reliability of electrical services. In this context, this dissertation explores the collaborative operation of microgrids, leading to the formation of multi-microgrids — a network of interconnected microgrids that facilitates energy exchanges within the cluster. By comparing the operational and economic outcomes of three microgrids in both isolated and collaborative scenarios, the study highlights the advantages of cooperation. Collaborative operation allows for the redistribution of excess generation to microgrids in need, minimizing wasted energy and enhancing revenue for one agent while boosting reliability and resilience for others.
