This chapter offers an adaptive virtual impedance method applied to a multi-VSG grid. The core idea is to change the output active power by adaptive virtual impedance. When the angular frequency of the local controller is greater than the angular frequency of the neighbors’ controllers, the output active power of local VSG falls, and thus \(\frac{{d{\omega _i}}}{{dt}}\) rises. Then, as the angular frequency is lower than neighbors’, the output active power rises, and \(\frac{{d{\omega _i}}}{{dt}}\) falls. As a result of this, the method facilitates the consistency of response curves of all angular frequencies. Besides, the stability of the offered algorithm is demonstrated. A final proof of the efficacy of the presented control method is shown by simulation and hardware-in-loop (HIL) results.
