The need for cleaner and more efficient electrical power generation along with the limited budget for construction of bulkygeneration and transmission facilities have motivated power system utilities toward deployment of distributed energy resources (DERs). On-site generation by DERs offers various economic and environmental benefits for the end customers, utilities, and society. Among those benefits we can include enhancement of reliability and resilience of power delivery systems as well as deferring new investment for bulky generation, transmission, and distribution expansions. Furthermore, DER integration may lead to lower losses at the transmission system thus reducing emissions of large fossil-fueled power plants [1], [2]. DER integration has modified conventional centralized bulk generation concept and has introduced new notions, such as microgrid (μG) [3].
