HERNANDEZ AROSTEGUI, Diandra; HERRERA VENTA, Fernando Miguel; VILARAGUT LLANES, Miriam  e  SOUSA SANTOS, Vladimir. Modeling and simulation of an autonomous microgrid. Energética [online]. 2021, vol.42, n.2, pp. 36-47.  Epub 29-Jun-2021. ISSN 1815-5901.

In this work, an electrical microgrid is modeled and simulated. Its generation scheme has a photovoltaic system and a generator that allows some autonomy in the event of disconnection from the electricity grid. Different operating modes were analyzed: microgrid connected to or isolated from the electrical network, as well as the disconnection of the microgrid from the SEN and the input of a generator set. The MatLab R2017b program was used, through its SimPower System tool. In each case, the behavior of the microgrid was analyzed in search of reliability and continuity in the electric power service. The load is simulated from the demand curve for 24 hours. To analyze its behavior, the operation of each of the components that make up the system was verified under the established working conditions, achieving adequate behavior in each case.
