Resilience enhancement strategies for power distribution network based on hydrogen storage and hydrogen vehicle

Abstract

In light of the increasing hydrogen permeability in distribution networks as a means to cope with extreme events and improve network resilience, this paper introduces a novel strategy for enhancing power distribution network resilience. It outlines a comprehensive approach that focuses on dispatching hydrogen storage (HS) and hydrogen vehicle (HV) within hydrogen penetrated distribution systems (HPDS), segmenting the strategy into pre-disaster and post-disaster stages. Firstly, in the pre-disaster stage, models for HS and HVs are established to gather operational data and facilitate rapid post-disaster response, alongside a coupled electric grid and road network model for optimising HV routing and dispatch. Subsequently, the post-disaster stage focuses on a scheduling model that aims to minimise load power losses and economic costs, balancing immediate power support with cost-effectiveness through detailed analysis of HS and HV dispatch strategies. Finally, this paper demonstrates the effectiveness of this strategy via a case study, highlighting significant improvements in network resilience and recovery and underscoring the potential of hydrogen technologies in enhancing infrastructure resilience.
