The Scenario Simulation of Electric Power Systems During and After Devastating Earthquakes and its Applications

The Scenario Simulation of Electric Power Systems During and After Devastating Earthquakes and its Applications

The service discontinuity of electric power systems in a devastating earthquake event can be temporally split into two phases. Phase 1 refers to the instant service discontinuity during the shock. Phase 2 refers to the following service discontinuity beginning a while after the shock when the systems start being restored. In this study, the procedures for estimating the remained capacity of a damaged power system in both Phase 1 and Phase 2 are discussed in detail. Following this, scenario simulation has been performed with the power system in Taiwan as an example. The power disruption caused by a devastating regional earthquake of highest potential has been attained. By employing hazard-consistent scenario earthquakes, the seismic risk of this system has been assessed. Transformers whose seismic damage contributes most to the power disruption have been identified.
