Applying Proactive Actions Before the Occurrence of Severe Natural Disasters to Increase the Resilience of Distribution Network

In recent years, the rate of occurrence of natural disasters has increased, which has led to extensive damage to the power system and extensive blackouts. preventive measures can be used in the distribution network to reduce the effects of severe natural disasters. preventive actions are opposite to reactive actions. preventive measures are taken before the incident and reactive measures are taken after the incident. In this paper, a mathematical model is presented to show the effects of preventive actions. In the proposed model, as soon as the accident is predicted, by predicting the exit of the damaged lines in the network using the Monte Carlo method, post-accident failure scenarios are generated. Then, in order to reduce the volume of calculations, scenario reduction is done using Gams. In the last stage, by implementing the proposed model, the optimal location for the installation of portable distributed generation sources and the repair team is determined. The simulation on different case studies shows that using proposed method results in considerable reduction of the energy not supplied (ENS) and the time of power outage for loads, which shows the good performance of the proposed method in facing to future disaster.
