Distribution System Service Restoration Strategy Considering Mobile Energy Storage Systems Dispatch and Repair of Transportation Networks

In the past few years, the study of the robustness of distribution systems (DS) has gained significant attention because of the frequent happening of severe natural calamities. This paper proposes a distribution service restoration (DSR) strategy in which the dispatch of multiple power sources and the repair of transportation networks were considered. The model can dispatch mobile energy storage systems (MESSs), renewable distributed generations (DGs), emergency power supplies (EPSs) and repair crews (RCs), and can repair the damaged branches and roads by RCs, which enhances the flexibility of MESSs and optimizes the utilization of available resources for service restoration. By employing methods that convert the model into a Mixed Integer Linear Programming (MILP) format based on polygons, problem solving becomes more efficient with the use of readily accessible commercial solvers. The effectiveness of the proposed model is confirmed through the utilization of the altered IEEE 33-node power distribution system as a case study.
