  7. Abstract:
  8. Necessity of uninterruptable electricity supply is one of the most fundamental needs nowadays. To achieve this, power system are designed and operated based on adequacy and security metrics which are based on reliability. Despite efficient influence of these metrics in normal condition, they do not have appropriate function while facing natural weather disasters. Since these events are low probability, these event do not affect adequacy metrics incredibly. Additionally, reliability metrics are compute base on intrinsic failure rate of component while each weather disaster causes specific failure rate. Furthermore, number of failures in such events is too many to be handled by N-1 operation metric. Accordingly, researchers are doing research on power system resilience and presenting measures to improve power system resilience. This research aims to analyze distribution system reconfiguration as a measure to improve resilience of distribution system which is the most vulnerable part of power system. At first, a method for simulating storm events and evaluating resilience metric has been presented. Additionally, necessity of reconfiguring in both restoration and infrastructure recovery stages has been discussed. Then road base repair crews routing has been introduced in order to model and optimize infrastructure recovery. After that, reconfiguration method aiming to maximize resilience metric and some other technical issues mentioned in thesis has been modified. Finally, case studies have been done on modified IEEE 34 node test system and modified 33 node test system. Analyzing results gives information about quality of distribution system resilience enhancement due to reconfiguration. Furthermore, effect of storm occurence time is seen
