Network modelling for harmonic studies



Power systems globally are experiencing a transition towards decarbonisation of electricity production through large-scale deployment of renewable energy sources (RES), which are gradually displacing conventional thermal plant. This changing environment is seeing a proliferation of power electronic converters connecting at all voltage levels in power systems, namely RES, FACTS devices, HVDC systems, domestic load, etc. These devices are highly non-linear and emit harmonics at the point of connection, but can also modify pre-existing harmonics in the network. In addition, increased installation of HVAC cables is creating system resonances at frequencies close to the characteristic emissions from these non-linear devices. As a result, many power systems are already experiencing an increase in harmonic distortion. Power quality issues associated with harmonics in power systems are becoming more pronounced and are driving the need to undertake detailed studies.

This webinar will summarise the outcomes of JWG C4/B4.38 “Network Modelling for Harmonic Studies”, captured in detail in Technical Brochure 766. The presenters will give an overview of the recommended tools and approaches for modelling the most common network components and non-linear devices. In addition, practical considerations will be discussed to aid the engineer in making informed decisions when performing harmonic studies.
