•NERC and a few utilities began to advocate

less-sensitive setpoints for tripping:

➢Keep DERs On-Line forDisturbances on BES.

➢Still enable tripping for Safety on Distribution Systems.

Q:

A: The Authority Governing Interconnection Requirements - the AGIR

Who Or What Is That?

Well, it Depends…

Defined in IEEE 1547-2018➢Can be a:

• Regulatory Agency• Public Utility Commission• Municipality• Co-Op Board of Directors

Defined in IEEE 1547-2018➢Authority may be delegated to the Area EPS operator or bulk power system

operator.

➢Decisions made by an AGIR should consider various stakeholder interests, including but not limited to:➢Load Customers➢Area EPS operators➢DER operator➢Bulk power system operator.

➢Annex B in Standard outlines considerations for Category Selection.

Still not entirely clear, but expect other players:➢Frequency is biggest concern for BES → NERC

➢PJM already working with their members to develop settings

➢Possible that ISOs will mandate frequency settings with no guidance on voltage

➢Voltage Requirements could then fall on Co-Op Board.
