“…In this way, the combination of V2G with GF control techniques is being explored to improve the ancillary services provided by the EVs connected to the grid [132]. This combination can be given by a bidirectional AC/DC charger [135] for every EV [136,137]. For this type of charger, a control technique to adjust the inertia of a V2G virtual synchronous machine (V2G-VSM) is proposed in [136], limiting the frequency change rate of the converter.…”

“…For this kind of solution, in [139], a V2G-VSM is proposed, based on synchronverter technology, to regulate the AC grid voltage amplitude and frequency, also considering the SOC of every EV battery. However, the effect of inertia and damping is not studied in detail [136], and communications between the VSM and the EV are required to determine the VSM power reference and droop coefficient. As has been commented, a DC distribution grid for EV connection provides several advantages.…”
