Microgrids Resilience Against Extreme Events in Distribution Power Systems: A Case Study

In recent years, power systems have suffered power failures caused by severe weather conditions resulting from climate change and global warming. These events can negatively affect the system equipment and lead to significant financial losses. Thus, mitigating these impacts on power systems using microgrids will help avoid power outages and ensure continuity of service. This paper presents a case study where the resilience of the microgrid based on a modified IEEE 37-bus feeder test system is tested and evaluated as performance indices without renewable energy resources. The proposed scenario mainly relies on conventional distributed generators as a resource to restore critical loads during night interruptions. The proposed framework uses two optimization algorithms to maximize the number of restored critical loads when faults occur in multi-location. The performed research lays out the importance of microgrids for distributed systems in the context of resilience, including different faults.
