Performance Specifications for Grid-forming Inverters - Status and Paths Forward

As grid-forming (GFM) inverters begin to be deployed, grid operators have identified a need to define minimum performance specifications for GFM and methods of validating GFM performance. This panel session will focus on GFM performance specifications and proposed methods of performance verification in different regions of the world. We will summarize GFM specifications in use and in development around the world; identify similarities, differences, and best practices in those specifications; and identify potential methods of GFM performance verification. By doing so, we will facilitate coordination and exchange of ideas for defining and confirming the desired performance GFM inverters, which are emerging as a key technology for the ongoing energy transition.
