Power quality impacts of the low carbon evolution within modern distribution networks

Crucially, this feature serves to embody the natural, diversity led attenuation of harmonic current flows in practical power systems. By contrast, the same effect is consistently found to be neglected for comparative examples in literature.<br><br>The aforementioned load model traits are employed in the time series, harmonic power flow simulation of representative demand profiles. This analysis is conducted upon a selection of power system models of real world, distribution networks.

For a mix of present day and future envisaged, demand profile mixes, several of the technologies trialled within the Smart Street project are observed to impart alleviative, power quality benefits to distribution network customers. This includes the installation of on-load tap changing transformers, as implemented at low voltage substations, the deployment of conservation voltage reduction and the application of meshing between adjacent low voltage feeders.
