The main difference with energy storage inverters is that they are capable of two-way power conversion – from DC to AC, and vice versa. It''s this switch between currents that enables energy storage inverters to store energy, as the name implies. In a regular PV inverter system, any excess power that you do not consume is fed back to the grid.

Energy storage, like wind and solar, uses inverters for converting direct current to alternating current to interface with the grid. Industry has historically classified inverter control technology as “grid-following” (GFL) or “grid-forming” (GFM) to represent the bookends of control characteristics, capabilities, and performance.
MISO is proposing a framework of GFM IBR requirements for stand-alone energy storage systems. This framework has two parts: 1) several functional capability and performance requirements defining voltage source characteristics; and 2) required simulation tests to demonstrate GFM characteristics and stable control responses.

GFM inverters can contribute to stability in weak grid areas, while traditional “grid-following” (GFL) inverters may become unstable under weak grid conditions, due to their reliance on tracking grid voltage set by other resources.
Studies conducted thus far indicate these numbers may be upwards of 30%.1,2,3 Since the current percentage of GFM resources is near zero in nearly all large, interconnected power systems, it is recommended to start requiring and enabling GFM in all future Battery Energy Storage System (BESS) projects for multiple reasons.
