Electricity management for persuing green and resilient airport in case of disaster: Including renewable energy sources, batteries, and diesel generators

Social infrastructures such as airports increasingly introduce a smart-grid in order to be ready against disasters. They cannot provide its function without electricity. Thus, a planning method for disasters or other uncertain situations has not been established, and it is getting difficult because there are many cases to be considered. In terms of electricity, demand in case of disaster changes according to each situation. Supply from renewable energy sources depends on the weather condition. This paper proposes a dynamic electricity management model for social infrastructures in case of disaster accompanying various electric damage. The model deals with renewable energy sources, batteries, and diesel generators. It can evaluate a quantitatively resilience index against disasters. It was applied to the data from Kansai international airport in Osaka, Japan in order to obtain the validity of the model. In general, this model suggests a better design of smart-grid for social infrastructures. It would enable them to become both green and resilient.
