The attached example shows how an AC current source (ElmIac) is controlled during a RMS simulation.

• In the first study case the amplitude and the angle of all phases are equally controlled, requiring a balanced network representation setting in the Calculation of initial conditions menu.
• In the second case the amplitude and the angle of the three phases are separately controlled, requiring an unbalanced network representation setting in the Calculation of initial conditions menu.

In both cases amplitude and phase are controller through a simple DSL model.
