The document summarizes changes being made to IEEE standards 1547 and 1547.1 regarding distributed energy resource interconnection. Key changes include: 1) Allowing distributed resources to actively participate in voltage regulation through volt-var functions; 2) Expanding adjustable voltage and frequency ride-through requirements; 3) Allowing modulated power output in response to frequency changes. Revisions to 1547.1 will include new tests for these functions. There is also discussion of starting a full revision of 1547 to include interoperability and remove the 10MW capacity limit.
