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;
- Excitation system…
