Probabilistic criteria for power system reliability management

Efthymios Karangelos Institut Montefiore, Université de Liège, Belgium

In today’s power systems, uncertainty is growing along with the growth of renewable generation and the ageing of the infrastructure. While technological opportunities to manage such uncertainty also advance, the inefficiency of the deterministic N-1 reliability management criterion is being recognized. In this setting, we propose novel probabilistic criteria considering threat probabilities, corrective control and its possible failure, and, the socio-economic impact of service interruptions.

The research leading to these results has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement No 608540, project acronym GARPUR ( This is joint work with Prof. Louis Wehenkel.
