Enhanced method for reliability of supply assessment - an integrated approach

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1374891

A comprehensive analysis of reliability of electricity supply to end users requires a unique set of models, methods and tools. Of special significance are long term power market models for predicting future operating states (generation and load patterns) and more detailed network simulation models f...

Vulnerability analysis related to extraordinary events in power systems

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1288187

A novel approach is developed for analyzing power system vulnerability related to extraordinary events. Vulnerability analyses are necessary for identification of barriers to prevent such events and as a basis for the emergency preparedness. Identification of cause and effect relationships to reveal...

Modelling of corrective actions in power system reliability analysis

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1288188

Consequence analysis, including the modelling of corrective actions, is an important component when performing power system reliability analyses. Using an integrated methodology for power system reliability analysis, we investigate the impact of different modelling choices for the consequence analys...

Impact of protection system reliability on power system reliability: A new minimal cutset approach

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1183937

In order to capture the effect of dependent failures that could arise due to the various transmission protection system response scenarios on power system reliability, complex Markov models or fault trees combined with event trees are typically employed in the predictive reliability studies. A uniqu...

Consideration of transmission protection system response in reliability of electricity supply analysis – case study

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1202759

A realistic appraisal of reliability attributes of electricity supply must also take into account an appropriate modelling and analysis of protection system response scenarios of transmission lines. Due to the prevailing transmission line backup protection coordination schemes, there exist several f...
