Vulnerability analysis of HVDC contingencies in the Nordic power system
In the increasingly interconnected and integrated European power system, transmission system operators need to consider new kinds of risk associated with the interconnection to neighbouring systems. For the Nordic power system, there is now more than 8 GW of HVDC interconnector capacity connecting t...
Smarter grids for reliable electricity transport
Electricity supply security – N-1 isn’t always enough
GARPUR proposes a new method to ensure secure power supply in Europe
On Improving Data and Models on Corrective Control Failures for Use in Probabilistic Reliability Management
Enhanced method for reliability of supply assessment - an integrated approach
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...
Modelling of corrective actions in power system reliability analysis
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...
Vulnerability analysis related to extraordinary events in power systems
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...
The impact of protection systems on power system reliability
This report is a collection of memos written to describe the methodology for quantifying the impact of protection systems on power system reliability. Including the effect of protection system response scenarios on a transmission system is vital for a realistic appraisal of the reliability attribute...
