Inverter Testing for Verification of Hawaiian Electric Rule 14H: Preprint

Research output: Contribution to conferencePaper


As utilities increasingly require inverters perform grid-supportive functions, it is challenging to ensure that those functions are properly configured in the field. This paper details inverter testing carried related to Hawaiian Electric's latest rule 14H interconnection requirements to validate that field installation procedures result in the intended advanced inverter behavior. The latest Volt-VAR, Volt-Watt, and frequency-Watt curves in Hawaiian Electric's Source Requirement Document (SRD) V1.1 for UL 1741 Supplement A were tested for two inverter manufacturers used in the utility territory. Both inverters were found to be largely compliant, though several discrepancies were identified and reported to the manufacturers to be addressed. The results are presented and discussed here.
