Self-Supervised Graph Neural Networks for Optimal Substation Reconfiguration
Antoine Martinez, Balthazar Donon, Louis Wehenkel +1
Changing the transmission system topology is an efficient and costless lever to reduce congestion or increase exchange capacities. The problem of finding the optimal switch states…
Defending the power grid by segmenting the EV charging cyber infrastructure
Kirill Kuroptev, Florian Steinke, Efthymios Karangelos
This paper examines defending the power grid against load-altering attacks using electric vehicle charging. It proposes to preventively segment the cyber infrastructure that chargi…
Electric power system security: the case for an integrated cyber-physical risk management framework
Efthymios Karangelos, Louis Wehenkel
This paper concerns the security of the electric power transmission grid facing the threat of malicious cyber-physical attackers. We posit that there is no such thing as perfectly…
Cyber-physical risk modeling with imperfect cyber-attackers
Efthymios Karangelos, Louis Wehenkel
We model the risk posed by a malicious cyber-attacker seeking to induce grid insecurity by means of a load redistribution attack, while explicitly acknowledging that such an actor…
Optimal Transmission Topology for Facilitating the Growth of Renewable Power Generation
Emily Little, Sandrine Bortolotti, Jean-Yves Bourmaud +2
Transmission topology control is a tool used by system operators in the role of a control action taken into account as a preventive or corrective action relative to a specific outa…
Whither probabilistic security management for real-time operation of power systems ?
Efthymios Karangelos, Patrick Panciatici, Louis Wehenkel
This paper investigates the stakes of introducing probabilistic approaches for the management of power system's security. In real-time operation, the aim is to arbitrate in a ratio…
