Abstract
Electric power systems are prone to several threats. However, some potential threats e.g., extreme weather or natural disasters, are unavoidable and this can affect socio-economic activities, energy security, and also quality of life. Hence, improving the electric power grid resilience in order to reduce the impact from natural disasters has to be thoroughly studied and understood. This paper presents the challenges and advantages of having sections of a power distribution system constituted by networked microgrids (MGs) to efficiently manage distributed energy resources (DERs), in particular roof-top solar photovoltaic and battery energy storage systems, in order to improve the power distribution system resilience to natural disasters. In this regard, this paper provides a detailed resilience analysis process considering two major case studies, moderate damage and heavy damage, which are tested under different scenarios and levels of disruption, that are evaluated utilizing various resilience metrics. Test results indicate that networked MGs incorporating DERs show the potential to provide support to the power distribution system by scheduling the discharge of battery energy storage systems during outages and improve the resilience of the distribution grid to natural disasters.
