Which standard specifically addresses the interconnection of distributed resources with the grid?

• A. IEEE 1547 is the standard addressing the interconnection of distributed resources with the grid.
• B. NERC CIP covers interconnection standards.
• C. IEC 61850 covers interconnection of distributed resources.
• D. PRC-005 covers interconnection standards.

Answer: (A)

IEEE 1547 is the standard that specifically addresses how distributed resources connect to and interact with the electric grid. It defines the requirements for safe and reliable interconnection, covering how a DER should behave with the grid in terms of voltage and frequency ranges, synchronization, protection, and power quality. It also establishes anti-islanding protections so a DER disconnects if the grid goes down, preventing back-fed energy onto a dead line. Over time, the standard has been updated to include grid-support functions and interoperability features that reflect modern DER technologies, such as inverters and energy storage, and how these devices communicate with the utility and other equipment. The other options address related areas but not the interconnection specifics. NERC CIP focuses on cybersecurity for critical infrastructure, not how DERs physically connect to the grid. IEC 61850 is about substation automation and device communications, not the interconnection requirements of distributed resources. PRC-005 relates to protection system maintenance and coordination, not DER interconnection standards.
