Electrification of the transport sector introduces operational issues in electricity distribution network, such as excessive voltage deviation, substation overloading, and adverse power quality impacts on other network loads. These concerns are expected to grow electrification expands incorporate heavy vehicles trucks buses due their greater energy requirements higher charging Two strategies proposed support medium- heavy-duty chargers which address high demand mitigate disturbances...

This paper proposes a decentralised control strategy using droop-based to generate charging schedule for electric vehicles (EV). aims mitigate voltage rise caused by rooftop photovoltaic (PV) systems and phase unbalance loads in low-voltage distribution (LV) network. The also smooths the profile of network reduces variation between maximum minimum voltages. A modified IEEE 13 node test feeder with an LV based on semi-rural Australian town was used show impacts PV EV verify proposed strategy.

Electric vehicle charging applies a notable strain on the electricity network due to large load produced. This paper will examine these loads and their effect traditional using hosting capacity evaluate this impact. Three indices are proposed quantitatively describe capacity. The voltage deviation index describes changes in variations loading. substation power delivery analyses flow through as ratio of its rated determine utilisation if it is overloaded. current unbalance factor measures...

Electric vehicle charging applies a notable strain on the electricity network due to large load produced. This paper will examine these loads and their effect traditional using hosting capacity as method evaluate this impact. Two indices are proposed quantitatively describe capacity. The voltage sag index describes drop in normal loading with electric charging. substation power delivery analyses flow through ratio of its rated determine utilisation if it is overloaded. A case study...
