For a PV system or WTG without energy storage, the output power is random and limited by the environmental conditions. PV system has no power reserve or inherent rotor inertia. Furthermore, for the two-stage PV system, instead of the mimic swing equation control in VSG, its DC-link voltage loop is required through the AC/DC inverter.
