Question Title

* 2. With the 10 MVA limit from previous versions removed, can the new IEEE Std 1547 now be applied, as a whole, to resources connected to transmission or networked sub-transmission grids?

Yes, the standard may be applied to non-DER resources without further changes

No, this standard is only applicable to DER connected to typical primary and secondary distribution voltage levels and strikes a balance between distribution safety and bulk system reliability.

Question Title

* 3. What does IEEE Std 1547 specify for the reference point of applicability which may either be the DER unit’s terminals or the DER facility’s connection point with the grid?

Only performance capabilities and functions of distributed energy resources unit or facility. The standard does not specify any specific design to achieve the requirements.

DER design, performance capabilities and functions as well as the mandatory utilization of these capabilities and functions by the distribution utility.

Question Title

* 4. From which IEEE Std 1547 requirements are emergency and standby DER exempt?

From all requirements

From certain requirements, e.g., voltage and frequency ride-through, interoperability and communications

Question Title

* 5. Does IEEE Std 1547 specify voltage and frequency ride-through as a mandatory capability requirement for DER?

Yes, but voltage and frequency trip settings within “ranges of allowable settings” allow for coordination with distribution protection and safety. Tripping of DER by utility-owned relays outside these ranges should only be implemented on a temporary basis and be coordinated with the regional reliability coordinator.

No, a distribution utility may choose to deactivate voltage and frequency ride-through as they see fit.

Question Title

* 6. Are the new requirements still in question by a majority of the approx. 120 working group members and 389 balloters?

Yes, the majority of working group members and balloters does not agree that the new requirements are needed at this point in time.

No, both at working group level and at the end of the balloting process, more than 90% of the technical experts from various stakeholder groups agreed that the new requirements are needed at this point in time.
