A Deep Learning-Based Method for Power System Resilience Evaluation

Power systems are critical infrastructure in modern society, and power outages can cause significant disruptions to communities and individuals' daily lives. The resilience of a power system measures its ability to maintain power supply during highly disruptive events such as hurricanes, earthquakes, and thunderstorms. Traditional methods for quantifying power system resilience include statistics-based and simulation-based approaches. Statistics-based methods offer a retrospective analysis of system performance without requiring a physical model, while simulation-based methods necessitate detailed physical system information and often simplify real-world scenarios. This paper introduces a deep learning-based method for evaluating power system resilience using historical power outage data. The method leverages the generalization capabilities of deep learning models and incorporates socio-economic and demographic factors as weighting terms to highlight the impacts on vulnerable demographic groups. The effectiveness of the proposed method is demonstrated through two case studies: one with real historical outage data and the other with simulated outage records. This approach provides valuable insights into measuring power system resilience against hazardous weather events without requiring a physical model of the target systems. The evaluation results can further guide the planning of distributed energy resources for resilience enhancement.
