TLDR
An integrated approach for reliability of supply analysis, assessing reliability and interruption costs down to the specifics of different kinds of end users at different delivery points in the network model is described.Abstract:
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 for analysing consequences of contingencies. This paper describes an integrated approach for reliability of supply analysis, assessing reliability and interruption costs down to the specifics of different kinds of end users at different delivery points in the network model. Furthermore, the effects of power system protection, temporal variation of parameters, and corrective actions as part of the consequence analysis, are taken into account in the presented integrated approach. The results are illustrated through a case study on a realistic hydro dominated four-area meshed test system.read more

A graph-based modelling framework for vulnerability analysis of critical sequences of events in power systems
TL;DR: A vulnerability analysis methodology based on the modelling framework is proposed that allows for identifying how critical consequences might occur as well as estimating their likelihoods of occurring and incorporates a possibilistic uncertainty analysis to explicitly capture uncertainties associated with the likelihood of events.

The impact of protection system failures and weather exposure on power system reliability
TL;DR: The results show that the inclusion of protection system failures can have a large impact on the estimated occurrence of higher order contingencies for adjacent lines, especially in periods of high weather exposure.

Transmission line unavailability due to correlated threat exposure
TL;DR: A new method of calculating time-series of component unavailability due to external threats based on historical data is demonstrated that shows that the simultaneous unavailability of multiple transmission lines may be significantly larger than estimated using traditional reliability analysis.
