Description

This standard establishes the required interconnection capability and performance criteria for inverter-based resources interconnected with transmission and sub-transmission systems. Included in this standard are performance requirements for reliable integration of inverter-based resources into the bulk power system, including, but not limited to, voltage and frequency ride-through, active power control, reactive power control, dynamic active power support under abnormal frequency conditions, dynamic voltage support under abnormal voltage conditions, power quality, negative sequence current injection, and system protection. The standard shall also be applied to isolated inverter-based resources that are interconnected to an AC transmission system via a dedicated voltage source converter high-voltage direct current (HVDC-VSC) transmission facilities; in these cases, the standard shall apply to the combination of the isolated IBR and the HVDC-VSC facility and shall not apply to the isolated IBR unless they serve as a supplemental IBR device that is necessary for the IBR generating facility with HVDC-VSC to meet the requirements of this standard at the reference point of applicability. Purpose This standard provides uniform technical minimum requirements for the interconnection, capability, and performance of inverter-based resources interconnecting with transmission and sub-transmission systems. Abstract New IEEE Standard – Active – Draft. Uniform technical minimum requirements for the interconnection, capability, and lifetime performance of inverter-based resources interconnecting with transmission and sub-transmission systems are established in this standard. Included in this standard are performance requirements for reliable integration of inverter-based resources into the bulk power system, including, but not limited to, voltage and frequency ride-through, active power control, reactive power control, dynamic active power support under abnormal frequency conditions, dynamic voltage support under abnormal voltage conditions, power quality, negative sequence current injection, and system protection. The standard also applies to isolated inverter-based resources that are interconnected to an AC transmission system via dedicated voltage source converter high-voltage direct current (VSC-HVDC) transmission facilities; in these cases, the standard applies to the combination of the isolated IBRs and the VSC-HVDC facility, and not to an isolated IBR on its own.
