Abstract

Due to the significant economic and technical damage caused by natural disasters, there has been a recent focus on resilience studies for distribution systems (DSs) after such events. This paper suggests a two-stage hierarchical approach using networked microgrids (NMGs) to minimize the value of lost loads (VoLLs) in the DS following a natural disaster. The first stage considers the energy generation limit of generating units in post-incident conditions when scheduling microgrids and DS. In the second stage, network reconfiguration and unit rescheduling are employed to reduce the VoLL in the entire network while maintaining the independent goals of each microgrid. The modified IEEE 123-bus test system is used to demonstrate the effectiveness of this approach, which effectively reduces the VoLL in the entire network while preserving the independent goals of each microgrid.
