The photovoltaic inverter shows that the grid is over-frequency

Inertia, frequency regulation and the grid – pv

Broadly speaking, there are two main ways to use inverters for frequency control: grid-following or grid-forming. Grid-following inverters measure the grid voltage and frequency, and inject the correct real and reactive power.
