Natural events having a low occurrence probability and high impacts, such as windstorms and earthquakes, pose a danger to the distribution networks' optimal performance. To increase network resiliency, several o. Due to the growing number of high-impact events, a massive effort is being conducted to. Due to the techno-economic challenges of expanding current distribution lines, distributed energy resources (DERs) might be an effective alternative for delivering electricity to clien. This paragraph describes the overall formulation covered in this paper. The following sections outline the major elements and optimization limitations of the planning approach. A standard 33-bus DS with 12.66KV base and 8 MVA was used to test the planning model as shown in Fig. 2. The substation linked to bus 1 products 6 MW and 3MVAr of act. This paper utilizes the presented planning model to examine the optimal operating of 33-bus DS's in both the normal and resilient operating modes. The location of RESs and energy storage s.
