| Abstract | In this study, we address the optimization problem of reducing the power restoration period after a major natural disaster. To improve the resilience of power restoration at each demand location, we schedule repairs to the fault locations along the power grid, and reconfigure the power grid as components in the grid are repaired. Most repair scheduling and network reconfiguration co-optimization problems considered only a radial network as the power grid configuration, with a small number of switches that determine whether a line is operational or not. In addition, despite the need for long-term scheduling, they approached it as a traditional scheduling problem that did not consider for off-hours. The value of this research is to propose optimal network configures and repair schedule considering off-hours and a smart grid with multiple power supply routes and power sources. To achieve this, we introduce a mixed integer linear programming and a matheuristic that takes into account the complexity of the problem. |
