Impact Analysis of Seismic Events on Integrated Electricity and Natural Gas Systems

Seismic events can cause devastating impacts on both overground and underground energy system infrastructure. This paper proposes a methodology to evaluate the impact of seismic security integrated electricity gas system, mainly focusing pipelines leakage connection loss transmission lines. A stochastic model is used formulate damage level based earthquake severity. The classified according levels pipe leak line failure. Load curtailment due limited generation capacity overloaded lines thereafter quantified. intensity generated randomly Monte Carlo simulation so that certain be related relevant load curtailment. An with 30-busbar 6-node natural network demonstrate effectiveness proposed method. results clearly illustrate consequences under in terms probability severity levels. work inform resilience enhancement scheme design vulnerability performance systems.
