ESIG Report Aims to Boost Grid Stability with New GFM Resource Metrics

ESIG, a nonprofit supporting grid transformation, has released a report advising on performance metrics for grid-forming (GFM) resources. This comes as transmission grids face reliability challenges from increasing inverter-based renewable sources.

The report, focusing on test methods and metrics for evaluating voltage source behavior, suggests pass/fail transient tests for abnormal grid conditions. ESIG recommends adapting performance metrics based on system characteristics and quantifiable objectives to improve system strength and stability.

Key organizations like IEEE, IEC, KIT, and industry consortia are actively involved in developing and applying test methods and specifications for GFM resources. These resources can be enabled through software changes and are valuable for battery storage capacity in interconnection queues.

Early deployment of GFM resources can mitigate reliability challenges and reduce transmission infrastructure investment. Texas grid operator ERCOT and Midcontinent operator MISO have already proposed and developed GFM specifications for future transmission-connected battery energy storage systems.
