  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. DG MV/LV 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

  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
