In the presence of devastating natural disasters like earthquakes, landslides, tsunamis and hurricanes, the resilience studies of power systems become extremely important. Since natural or man-made disasters cause huge damages especially to the electric power systems, further studies are required on resiliency particularly in recent years due to the tremendous impact of global climate changes [1]. Power system resilience is defined as the flexibility of the electric network that can be recovered immediately after an unpredicted, adverse event occurs such as a natural or a manmade disaster [2]. Microgrids (MGs) have a great potential to enhance important parameters of distribution grids such as reliability [3], environmental benefits [4], and techno-economic performance. The modern structure of MGs, in which MGs have a great flexibility to connect to each other and to the main grid is called networked MGs (NMGs). In this structure, MGs can operate in both interconnected and islanded modes. Therefore, the resilience of distribution grid can enhance due to sharing of power between MGs after occurring an unpredicted disaster [5]. The concept of NMGs is the main issue in mitigating the operation costs of distribution network through optimal operation of MGs [6]. In fact, designing an efficient energy management system (EMS) is a key factor to ensure a reliable
