SUMMARY:

Microgrids represent the future of electrical power systems, and for them to function properly, a microgrid energy management system (MEMS) must be designed to find the best way to handle the load reliably. This study aims to objective to propose and simulate a MEMS for a microgrid located at the University of Brasília and composed of three distributed energy resources (REDs): photovoltaic panels, biogas thermoelectric plant and a battery energy storage system. For the simulation it was necessary collect information on the consumer unit’s consumption profile and energy potential to so that REDs could be scaled well. The suggested algorithm was developed for connected and islanded modes, seeking to prioritize the photovoltaic system and considering the state of burden on decision making. The schedule must also be monitored in order to reduce or cut the network's contribution to peak period load, as an ancillary service. Simulations were carried out for specific weeks and for the entire year 2023, with the aim of validating the system power management system and check for possible shutdowns. Considering the annual scenario, the minimum and maximum photovoltaic generation was 30.33 and 41.59 MWh in the months of April and November, respectively, while the largest load consumed was in the month of May, reaching 78.56 MWh. The power supplied by the grid ranged between 12.63 MWh and 33.21 MWh, with a reduction of more than 60%. Furthermore, the total cost of energy consumed by each source was evaluated, by microgrid and how much would be spent by the system without the microgrid. The results of the simulations were very positive, with good responses to network interruptions and achieving savings in R$318,579.49 in 2023.
