Introduction
• Deregulation of the market: facilities to new producers
• Increase the order of the mathematical model• Need of model reduction to simplify studies:
– Impacts studies, real-time energy management, control regulation design,…

Dynamic Reduction
• Modal Reduction Analysis– Particularly interesting to stability studies,
computation of generator regulations gain
• Dynamic equivalents– Physical model
– Aggregated equivalent load
– Aggregated equivalent generator

Conclusions
• Test of different methodologies of reduction• Reduction of the number of variables to compute in
the programs• Reduction in time simulation (ARENE simulator)• Possibility of model reduction implementation in a
tool
