Karangelos, E., & Wehenkel, L. (in press). Probabilistic Reliability Management Approach and Criteria for Power System Short-term Operational Planning. Probabilistic Reliability Management Approach and Criteria for Power System Short-term Operational Planning.
Peer reviewed
This paper develops a probabilistic decision making framework for reliability management in the short-term operational planning context. We build upon our recent work, which proposed a probabilistic ...
Duchesne, L., Karangelos, E., & Wehenkel, L. (2017). Machine Learning of Real-time Power Systems Reliability Management Response. PowerTech Manchester 2017 Proceedings.
Peer reviewed
In this paper we study how supervised machine learning could be applied to build simplified models of real-time (RT) reliability management response to the realization of uncertainties. The final objective is ...
Marin, M., Karangelos, E., & Wehenkel, L. (2017). A computational model of mid-term outage scheduling for long-term system studies. PowerTech Manchester 2017 Proceedings.
Peer reviewed
This paper presents a computational model of the mid-term outage scheduling process of electric power transmis- sion assets, to be used in long-term studies such as mainte- nance policy assessments and ...
Karangelos, E., & Wehenkel, L. (2016). Probabilistic reliability management approach and criteria for power system real-time operation. Power Systems Computation Conference.
Peer reviewed
This paper develops a probabilistic approach for power system reliability management in real-time operation where risk is a product of i) the potential occurrence of contingencies, ii) the possible failure of ...
Perkin, S., Bjornsson, G., Baldursdottir, I., Palsson, M., Kristjansson, R., Stefansson, H., Jensson, P., Karangelos, E., & Wehenkel, L. (2016). Framework for Threat Based Failure Rates in Transmission System Operation. Framework for Threat Based Failure Rates in Transmission System Operation.
Peer reviewed
Reliability of electrical transmission systems isvpresently managed by applying the deterministic N-1 criterion, or some variant thereof. This means that transmission systems are designed with at least one ...
Gemine, Q., Karangelos, E., Ernst, D., & Cornélusse, B. (2013). Active network management: planning under uncertainty for exploiting load modulation. Proceedings of the 2013 IREP Symposium - Bulk Power Systems Dynamics and Control - IX. IEEE.
Peer reviewed
This paper addresses the problem faced by a distribution system operator (DSO) when planning the operation of a network in the short-term. The problem is formulated in the context of high penetration of ...
Karangelos, E., Panciatici, P., & Wehenkel, L. (2013). Whither probabilistic security management for real-time operation of power systems ? Bulk Power System Dynamics and Control - IX Optimization, Security and Control of the Emerging Power Grid (IREP), 2013 IREP Symposium. IEEE.
Peer reviewed
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 rational way between preventive ...
Mathieu, S., Karangelos, E., Louveaux, Q., & Ernst, D. (2012, October 08). A computationally efficient algorithm for the provision of a day-ahead modulation service by a load aggregator. Poster session presented at DYSCO Study Day : Dynamical systems, control and optimization Kickoff of phase VII.
We study a decision making problem faced by an aggregator willing to offer a load modulation service to a Transmission System Operator (TSO). In particular, we concentrate on a day-ahead service consisting of ...
