The introduction of data communications represents a sea change for the Distributed Energy Resource (DER) industry. New communication requirements in the IEEE 1547-2018 standard for DER, and the introduction of the IEEE 2030.5 and IEEE 1815 communication protocols that the IEEE 1547 standard references, will affect every part of system operation—including finance, permitting, interconnection, operations and maintenance. These protocols, inherent in smart inverters, gateways or other communication devices, also introduce a new responsibility for DER systems to support cybersecurity. Aim/Objective: This session will review applicable standards—what they are, what they do, and early lessons learned through a recently-completed California Rule 21 test and field trial project—to assist attendees in being prepared for the IEEE 1547-2018 roll out across the U.S. starting in 2020. Every major DER market in the U.S. (approximately half the states) will be affected. Methods: The session will update participants on the IEEE 1547-2018 national rollout, including the current status of CA Rule 21 and its implementation of the IEEE 2030.5 standard. It will explore the relationship between IEEE 1547-2018 and IEEE 1547.1, describe changes to the 2018 revision of the IEEE 2030.5 standard, and illustrate how this standard is implemented according to the SunSpec Common Smart inverter profile (CSIP). Results from the SunSpec project titled “Interoperability Standards and Open Testing Framework to Support High-Penetration Distributed Photovoltaics and Storage” will be used to illustrate key impacts of the IEEE 1547 and IEEE 2030.5 standards. Dr. Robby Simpson, System Architect at GE Grid Solutions, and Tom Tansy, Chairman of the SunSpec Alliance, will co-present in order to provide a high-quality experience for participants. Conclusion: Attendees will gain an understanding of how data communications are impacting DER equipment and interconnection requirements, the rollout of these protocols by state, utility and aggregator communication structures emerging in the market, and responsibilities and implications for cybersecurity and the emerging DER digital security landscape.
