Work in progress / futur work:

Iusing new synchonous machine models;

Probabilistic studies;

Taking advantage of finite elements methods (coupling?);

Comparison with phasors domain approach;

Simulate more events : inter coil faults in transformers, islanding …

More accurate modeling of :

- Auxiliary systems;

- Grids;
