Robust Methods for Harmonics Compliance Study

current

The Robust Methods for Harmonics Compliance Study aims to develop a robust methodology for the harmonic compliance assessment processes. The Robust Methods for Harmonics Compliance Study acknowledges that there are significant challenges associated with the assessment of compliance of harmonic emission with allocations provided by Network Service Providers (NSPs). The current regulatory guidelines are not prescriptive and do not account for the recent complexities of the energy system caused by Variable Renewable Energy (VRE). As a result, NSPs are implementing individual compliance assessment methodologies that vary by region, potentially leading to inconsistent outcomes, unnecessary curtailment, and over investment in harmonic mitigation equipment. The Robust Methods for Harmonics Compliance Study aims to address these challenges by developing a robust and prescriptive methodology for the harmonic compliance assessment processes. This will be used as an interim best practice guideline for voluntary use by participating industry stakeholders, and as the basis for a submission to amend the Australian Standards and potentially the National Electricity Rules.
