A power-frequency model of synchronous machines is employed to design a virtual inertial controller for implementation of an inductive electric charging system. The proposed control strategies are twofold; an outer control loop used to generate power reference based on frequency fluctuation in a real time manner, and a multi-power-level control tuned based on the power reference used as an inner control to change the number of quantum energy-injection pulses applied to the inductive charging system. This can help accelerate the power oscillation damping. Simulation results show the improved virtual inertial response with the developed inductive EV charging system.
