While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
How do grid-connected inverters work?
It focuses on how grid-connected inverters should behave when the main power supply is interrupted. In simple terms, it ensures that inverters stop sending power to the grid when the grid itself is down. This prevents a dangerous condition known as islanding.
How do inverters provide grid services?
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
How do grid-following inverters work?
Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid. In these systems, the power from the grid provides a signal that the inverter tries to match.
