Abstract

The power grid is one of the most important infrastructures of modern societies, which requires safe and effective operation. In this regard, the design of power networks should be such that they can be resistant to power outages. In the meantime, the discussion of the resilience of the power grid is raised. The goal of the resilient grid is to adapt to high-risk events with a low probability of occurrence, such as severe natural disasters and human attacks. In this paper, a two-stage framework is proposed to improve the resilience of distribution systems using network rearrangement with risk-based quantitative methods. The conditional risk value to change the network topology in such a way as to reduce the probability of load interruption. In the second step, after the accident and the identification of the interrupted lines, another re-arrangement step should be done to minimize the interruption of the load, in which the genetic algorithm is used. The model is evaluated on a 33-bus distribution network and its results are presented.
