Implement the controller in the average Plecs model. Provide an AC current reference that enables the exchange of a desired active power and zero reactive power. Show that the close loop control can follow the current reference in steady state, commenting on any discrepancies you find. In addition, show the response of the system to the following transients: case A$)$ power step from $0$ to P$/2$ and from P$/2$ to P and case B$)$ power step from $0$ to $$P$/2$ and from $-$P$/2$ to $$P and discuss how it relates with the expected closed loop performances.
