Transmission System Operational Risk Assessment and Mitigation
Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
As transmission networks are getting older and as their components are reaching their life span’s end, the number of maintenance outages for equipments reparation or replacement is destined to gradually increase in the coming years. These outages weaken system’s security and lead to highstress situations that often do not comply with N-k operation rules. Thus in-depth risk analysis have to be performed in those cases, to ensure system’s smooth operation and optimal maintenance planning. It requires a comprehensive knowledge of contingencies consequences on system and society, but also refined contingencies occurrence probability estimations. This integration of probabilistic issues in operational problematic is challenging as current doctrines are profoundly deterministic, however the methodology developed here aims to comply with those while preparing the ground for future risk-based doctrines. Finally, integration of curative and preventive risk mitigation means gives more visibility to contingency probability reduction means and measures their economic efficiency, which leads to more optimal decision-making than the only use of classic consequences reduction techniques. This easily implementable method makes accessible new information to operators, allowing them to limit the use of systematic conservative and costly risk mitigation strategies.
