Reliability in future electricity mixes: the question of distributed and renewables sources

Pushed by the need for carbon emissions abatement and the expected depletion of fossil fuels, electricity generation is entering a period of signicant changes. Currently, integrating distributed and renewable energy sources questions the shape of the future electricity industry. In this paper, we are interested in the level of reliability in future electricity mixes and in whether or not these changes impact the level of reliability. Consequently, we propose a methodology to assess reliability of power systems relying on a few aggregated physical properties. Finally, we then exhibit \reliability indicators", that help to provide valuable comments on reliability with distributed and renewable energy sources. To sum up, changes in the electricity industry must be done carefully with respect to reliability requirements.
