The aim is to develop a robust methodology for the harmonic compliance assessment processes.


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 University of Wollongong 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.


The findings of this project will produce a harmonic compliance assessment process and a recommendation for harmonic voltage planning levels.

Bringing national harmony to harmonic distortion

The transition to renewable energy faces many challenges, including the growth of subtle yet profound factors that require an overhaul of national standards and regulations.
