1. 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,…

2. Static Reduction Aggregation of different networks components
Comparison with ARENE simulator

3. Dynamic Reduction Modal Reduction Analysis Dynamic equivalents
Particularly interesting to stability studies, computation of generator regulations gain
Dynamic equivalents
Physical model
Aggregated equivalent load
Aggregated equivalent generator DG
MV/LV

4. Dynamic Reduction
Voltage profile comparison in an urban French network
0.3% deviation in the worst case

5. 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
