The frequency response is assessed following largest power infeed loss by plants technology (IBR or synchronous generator). The results demonstrate that inverter-dominated grid mainly impact frequency stability rather than voltage stability, with the disconnection of weaker PV plants during faults leading to underfrequency load shedding.
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
A grid-forming inverter operating in Virtual Synchronous Machine (VSM) mode emulates the behavior of a synchronous generator by establishing the grid’s reference voltage and frequency. In doing so, it contributes virtual inertia and damping to stabilize frequency and voltage while facilitating power sharing among inverter-based resources.
