Vulnerability mitigation is the solution for creating resilient distribution networks aims to prevent the uncontrollable outage propagation. This paper presents a new resilience index as a powerful tool to enhance the
resilience of distribution systems against extreme hurricane events. The suggested framework provides a
comparative study for optimal feeder routing problem and HV substation placement from the cost and resilience
viewpoints. Once, the network is planned based on cost minimization, and then the proposed resilience index is
calculated for the planned network. Finally, the network is planned based on resilience enhancement and afterward the planned network’s cost is calculated. In case of resilient-based planning, the studied area is divided
into small sites with different wind speed to evaluate the geospatial characteristics of hurricane and a fragility
index is calculated for each distribution network component located at each sites. Both cost- and resilient- based
networks are planned using deterministic and probabilistic approaches. In deterministic approach, network
planning is done according to the worst prediction, the highest wind speed. But in probabilistic one, some
scenarios with specified probability are defined for wind speed. Results show that, fragility index is high when
considering worst prediction, so this less probable scenario needs higher investments. In this regards, scenario
based planning, can lead to the best compromised solution considering cost and resilience which the obtained
results validate the accuracy of the modellings and efficiency of the proposed method
