When using Simulink with SimPower Systems blockset (PSB) you have to use a block called "powerGUI".
There you can specify a sample time, when simulation type is discrete.
Still you can choose another sample time or even continuous solver in "normal" simulink 'Model Configuration Parameter' window.
Will there be a cont. or discrete analysis ? What's the difference between those two options ? Why do I need them both ?

This is like using a Simulink discrete block while setting the global solver to variable-step. The power systems part would be discrete if a discrete rate is selected. But some parts of the model might still run in continuous time (controlled by the global solver) if continuous Simulink blocks are used in the model.
