When there is a large disturbance or outage on the grid, conventional inverters will shut off power to these energy sources and wait for a signal from the rest of the grid that the disturbance has settled and it is safe to restart—known as "grid-following.". As wind and solar account for increasing shares of the overall electricity supply ...
