COMMUNICATIONS PROTOCOL REQUIREMENTS Clause Samples

COMMUNICATIONS PROTOCOL REQUIREMENTS. IEEE 1547 Clause 10.7 specifies the communication protocol requirements and requires that the DER support at least one of the protocols listed in Table 6-14. The Local DER Communications Interface must be active when the DER is operations operational and have an information response time of less than or equal to 30 seconds. Table 6-14: DER Communication Protocols15 IEEE Std 2030.5 (SEP2) TCP/IP Ethernet IEEE Std 1815 (DNP3) TCP/IP Ethernet SunSpec Modbus TCP/IP Ethernet 15 IEEE-1547-2018 Table 41, page 75 This Section outlines technology-specific requirements for DER Facilities. Company requires that the Customers DER Facilities interconnecting with the Company Distribution System meet the technology-specific the requirements unless specified otherwise in the DER Interconnection Agreement. 7.1 DER Units with Inverter-Based Interfaces 7.1.1 Inverter Standards Company requires that the “Inverters” of all DER Units with inverter-based interfaces be certified compliant with the Inverter standards/guidelines outlined in Table 7-1. Table 7-1: Inverter Standards/Guidelines IEEE 1547-2018 Inverters shall be Smart Inverters certified compliant with IEEE 1547-2018 “IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces”. IEEE 1547.1 Inverters shall comply with the most current release of IEEE 1547.1 “IEEE Standard Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems” (new release in 2020) UL 1741 Inverters shall be certified safety compliant under UL 1741 “Standard for Inverters, Converters, Controllers and Interconnection System Equipment for use with Distributed Energy Resources” UL 1741 SA UL 1741 SB Inverters shall be certified compliant as Grid Support Utility Interactive Inverters under either UL 1741 SA or UL1741 SB until 01/01/2022. After 1/1/2022, inverters shall be certified compliant under UL 1741-SB Company recommends that Customer propose Inverters listed as compliant on the California Energy Commissioner’s (CEC) list of eligible Inverters available at the following location: Customer may propose Inverters that are not listed on the CEC list, but additional time will be required to verify certification and compliance with the outlined requirements. Inverter settings will be determined by the Company. The Company will have the ability to view, modify/control DER operations through the inverter functions/setpoints. 7.1.2...
