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.

The opportunity arises from a combination of current control technology availability and increasing level of energy storage interconnection requests within MISO. Given the industry landscape, in 2023, NERC recommended all newly interconnecting battery energy storage systems (BESS) have “grid-forming” (GFM) controls.
The battery design of the electrochemical energy storage system adopts 3.2 V/220Ah lithium-ion battery. The system is arranged by 18 battery cells in series and 90 battery cells in parallel, with a total number of 1620 cells.
33 As an example, if the phase difference between the inverter terminal and the grid increases, the resource should increase (or make less negative) its active power injection in the sub-transient time scale. If the phase difference reduces, it should result in a reduction of its active power injection in the sub-transient time scale.
