Microgrid Integration into Brazilian Distribution Networks: A Demand Response Case Study

Renewable energy hybrid mini-grids have experienced significant growth in power systems, driven primarily by the need for more resilient and reliable distributed resources in modern power systems. However, despite their many benefits, the combined operation of PV and storage systems can pose challenges in system management and coordination, especially in radial distribution networks. This paper examines the operation of microgrids in a real medium-voltage radial feeder in Brazil, incorporating distributed generation and capacitor banks. Additionally, it assesses network losses with and without implementing distributed energy resources. The study considers the role of battery energy storage systems in energy and demand response, in addition to various load and an island mode operation scenario. The findings emphasize the advantages of effectively managing hybrid microgrids, highlighting enhanced reliability and service continuity in the face of diverse disturbances.
