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,…

Static Reduction Aggregation of different networks components Comparison with ARENE simulator

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

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

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
