Abstract

Static load models, including ZIP coefficients, are an established facet of power systems modelling. Despite therising penetration of non-linear load types across modern networks, the characterisation of load behaviours by such
means remains effective. However, the accuracy of ZIP load-based methods is shown to decline in the midst of highlevels of harmonic current and/or voltage distortion. This observation is validated by making reference to the
definitions set out in IEEE standard 1459-2010. Various power systems optimisation strategies, such as Conservation Voltage Reduction, rely on load models to faithfully reproduce network conditions in simulation. Thus, an extension to the conventional ZIP model approach is proposed, which incorporates the effects of harmonic current distortion, attributable to particular load types, and harmonic voltage distortion.
