Resilience Enhancement of Electricity-Heat-Hydrogen Integrated Energy System under Ice Disasters

Ice disasters pose severe challenges to the secure operation of distribution networks and integrated energy systems. This study develops a dynamic failure model for power distribution systems under ice disasters and establishes a coordinated optimization framework for an electricity-heat-hydrogen integrated energy system. The Monte Carlo simulation is utilized to represent the stochastic component failures induced by ice accretion, enabling a realistic assessment of system performance under extreme icing disturbances. Furthermore, a combined electricity-heat resilience metric is proposed to quantify the system's capacity to resist and recover from major icing disturbances. Case studies demonstrate that the proper configuration of hydrogen energy facilities can significantly reduce supply shortages and enhance the overall resilience of the electricity-heat-hydrogen integrated energy system during ice disasters.
