In recent years, power systems have suffered powerfailures caused by severe weather conditions resulting fromclimate change and global warming. These events can negativelyaffect the system equipment and lead to significant financial losses.Thus, mitigating these impacts on power systems using microgridswill help avoid power outages and ensure continuity of service.This paper presents a case study where the resilience of themicrogrid based on a modified IEEE 37-bus feeder test system istested and evaluated as performance indices without renewableenergy resources. The proposed scenario mainly relies onconventional distributed generators as a resource to restorecritical loads during night interruptions. The proposed frameworkuses two optimization algorithms to maximize the number ofrestored critical loads when faults occur in multi-location. Theperformed research lays out the importance of microgrids fordistributed systems in the context of resilience, including differentfaults.
