Security of supply in power system supposes that the robustness of the system can be guaranteed in case of credible contingencies. This robustness relies on structural redundancy and on security margins. Traditionally, the "N-1" contingency analysis has been used for such check. This methodology leads to the definition of "sizing incidents", or credible contingencies. The

We visit three problems that use domain knowledge to better design learning models that are physics-informed and risk-aware 3 Risk-aware learning for grid-edge coordination: Reduced risks of voltage violations Topology-aware learning in large-scale power systems:
For each power system, we consider five different contingency budgets k = 0,1,2,3, and 4. Altogether, we consider 10 instances. Table I compares the run times for the three different approaches. For each of the 10 instances, m provides the number of distinct contingencies.
Contingency analysis is a mathematical method for predicting equipment failure or a specific line''s failure and taking corrective action before the system enters an unstable state.
Contingency planning refers to the process of preparing for potential emergencies or unexpected events that could disrupt normal operations. It involves identifying possible risks, assessing their impact, and developing strategies to mitigate those risks, ensuring that organizations can maintain or quickly restore their functions in the face of adversity. Effective contingency planning is

Contingency is the loss or failure of one or more components in the power system. Contingency can also be defined as a specified set of events occurring within a short duration of time [1]. Contingency in a system may be none, severe or critical. None: The system restores itself to pre-disturbed state after a contingency.

This study examines the use of bilevel programming to analyse the vulnerability of power systems under multiple contingencies. One of the main purposes of this study is to explain the state of the art of the subject matter. A minimum vulnerability model and a maximum vulnerability model are presented and discussed. In both models, the upper-level optimisation determines a set of
