Objectives The significant integration of Electric Vehicles (EVs) presents various challenges to the development and operation of the LV network. High penetrations of EVs can lead to substantial increases in the demand being required for the purposes of charging the EV batteries. This introduced new customer demand patterns at the distribution level, which could cause adverse effect to network areas where large groups of EVs are charging simultaneously. Such effects could include excessive voltage variations, increased thermal loading, higher network losses and possibly harmonic distortions, which in turn, could lead to violations of the DNO planning limits and industry standards. Furthermore, the increased level of demand on LV feeders associated with the restoration of service after an outage, i.e. Cold Load Pick Up (CLPU), is of concern as it can be significantly higher than pre-outage levels, even exceeding the peak demand on the feeder that is observed under normal operating conditions. This increase in demand is mostly due to a loss of diversity among loads that are process controlled and/or thermostatically controlled such as heat pumps. The electrification of the heat sector is expected to drive the update of heat pumps potentially worsening the levels of CLPU on LV feeders. These high levels of CLPU demand that can persist for prolonged periods may increase the thermal loading of equipment, risking LV fusing operation, increasing restoration times and potentially damaging equipment. A CLPU event can be characterised by the magnitude and duration of the overload following supply restoration after an outage. Both quantities are necessary to: quantify the thermal impact to electrical equipment; inform the sizing of distribution network equipment; foresee potential problems during restoration; develop restoration plans; or assess insulation loss of life. Based on the above, this project seeks to understand: The technical impact the significant integration of EV charging load cause on the LV networks and explore how to translate the impact into LV design and planning practices. This project will quantify and assess the impact caused by EV load on the thermal and voltage limits and devise a simple and robust framework that designers can apply and use; and The technical impact that the significant integration of heat pump load causes on the LV networks during CLPU events. This project will assess the impact the magnitude and duration of CLPU, associated with different scenarios (feeder type, heat pump penetration level, season of year, time of day, outage duration etc.) has on the thermal and voltage limits.

The objective of this project is to undertake data analysis and modelling to: Assess and quantify the technical impact of significant integration of EVs on LV networks; Assess and quantify the technical impact that the significant integration of HP load causes on LV networks during CLPU events; and Provide an LV network design framework that will allow network planers to account for the impact of EV load and HP load during CLPU events on the design of LV network feeders.
