The attached has two sets of controls, one to maintain the capacitor DC voltage and the other one to charge/discharge the inductor. There is a set point for the 'Iq' reference as part of the six pulse bridge.If it is desired to include a reactive power control, this one can be setup by means of a PI controller, such that it modifies the 'Iqref' quantity within the 'Rectifier control page'. The angle yielded by the PLL has been setup such that the 'd' axis controls the active power, and the 'q' axis the reactive power.

This is SMES model, Can we use it as a Supercapacitor instead?
Faster and similar dynamics of Supercapacitor can be achieved rather than Batteries?
and is it compatible with version 4.5 as well?
