In Japan, meteorological severe disasters including typhoon have recently continued to occur and have been intensifying damage to infrastructures. On the basis of recent disaster experiences, particular attention is paid to issues related to “Resilience” as a key concept of disaster control measures for electric power systems. This presentation introduces simultaneous multiple accident cases and their countermeasures for electric power system against Typhoon. At first, as typical typhoon disaster in metropolitan area, the damage and emergency restoration process of the electric power distribution equipment, caused by Typhoons occurred in 2018, 2019, and 2020, are illustrated. In addition, electric power resilience working group, organized by METI, suggests that in order to increase regional disaster mitigation performance (regional resilience), a disaster information collecting and sharing system, and damage prediction system are needed for wide-area collaboration among power transmission and distribution network companies. As an example of resilience improvement of electric power system, recent our research and practical use cases including a damage prediction tool for electric power distribution equipment, are also illustrated.
