My problem with the CMSF components, is that it is difficult to model certain systems containing these components. As I have background in control engineering, which teaches us to model linear time invariant systems using a transfer function and converting it to state space model. With the new feature of Frequency Dependent Transfer Function (FDTF) available in PSCAD 4.6 free, could i use it to implement modeling of wide varieties of real world systems such as power system controls? Is there an example on how to use it? Thanks.
