Coordinated Restoration of Transmission and Distribution in Regional Power Systems Based on Large-Scale Renewable Energy Plants

The critical challenge of enhancing the restoration efficiency of regional power systems amidst the increasing penetration of renewable energy generation in transmission and distribution grids is addressed in this paper. To tackle these challenges, a novel method for decision-making on the resilience restoration of power transmission and distribution networks is proposed. Considering the uncertainty of load and wind power during restoration, an coordinated restoration of transmission and distribution optimization model is constructed. By establishing a boundary-coupled model, this method facilitates independent and coordinated solutions for restoration plans in both networks while ensuring information privacy protection among different dispatching level of electric power companies. The simulation results demonstrate the effective enhancement of the proposed method on both transmission and distribution network restoration processes, particularly in the context of integrating large-scale renewable energy plants.
