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.
