Se utilizó el programa MatLab R2017b, a través de su herramienta SimPower System, Se analizó en cada caso el comportamiento de la microrred en la búsqueda de confiabilidad y continuidad en el servicio de energía eléctrica. La carga se simula a partir de la curva de demanda durante 24 horas. Con el objetivo de analizar su comportamiento, inicialmente se comprobó el funcionamiento de cada uno de los componentes que conforman el sistema en las condiciones de trabajo establecidas, lográndose en cada caso un comportamiento adecuado.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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.]]></p></abstract>
