What is universal interoperability for grid-forming inverters (unifi)?The Department of Energy funded Universal Interoperability for Grid-Forming Inverters (unifi) Consortium, a multi-year effort underway to advance GFM technology, produced the second version of GFM specifications in March 2024. MISO reviewed and adopted several aspects of this work in requirements and guidance as well.
How do inverters work in energy storage?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.
Why do we need grid-forming controls for battery energy storage?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.
How do multiple mode inverters with energy storage reduce frequency?nse to a decrease in frequency for multiple mode inverters with energy storage is a two-stage response. The initial stage applies if the energy storage is being charged via the grid-interactive port of the inverter and requires a reduction in the power input level through the grid-interactive port, the second stage requires the inv.
