Integrated approach for security of electricity supply analysis

The methods and tools needed for security of supply assessment range from long term market models for predicting future generation and load patterns to more detailed network simulation models for analyzing contingencies and reliability of supply for delivery points. This paper describes an integrated approach for security of electricity supply analysis, by the integration of power system reliability analysis with the power market analysis. An integrated methodology will enable the long-term security of supply assessment and provide a more consistent input to the various analyses, as well as a better information exchange and interaction between the different methods and tools involved. The integrated methodology is under development in an ongoing research project focusing the power system reliability analysis, making it possible to take the risk of extraordinary events into account.
