Assessing the Impacts of Electric Vehicles on Australian Urban and Rural Grids

Free webinar

The increasing adoption of electric vehicles (EVs) poses significant technical and economic challenges on the power grid, particularly on the very infrastructure they are connected to – the electricity distribution network.

We have designed our distribution networks to cope with our peak demand. Depending on the State or Territory in Australia, the design value can vary from 3 to 7 kW per house (single phase) which accounts for diversity (we all use electricity at different times) and demographics (larger houses or colder places without access to gas consume more). Although our networks have been engineered to withstand demand growth, this does not include EVs.

The trend around the world is for EVs charged at home to use the fast level 2 chargers (around 7kW of demand). While all EVs will not be charged at the same time, they clearly are a concern for distribution companies as the extra demand could easily exceed what the infrastructure has been designed for. Therefore, we need to understand the extent to which our networks can host EVs.

This webinar presented the modelling considerations and results of a highly-granular, detailed EV hosting capacity assessment done on urban and rural networks in Tasmania, New South Wales, and Victoria. This involves fully modelled HV (22kV and 11kV) feeders, and pseudo low voltage (0.4kV) networks to capture the effects close to end users, time-series analyses, and rapid adoption of EVs.

This webinar is part of the 2 year collaborative project on ‘EV integration into the electricity grid’ between Energy Networks Australia (ENA), the Australian Power Institute (API), the Centre for New Energy Technologies (C4NET), and The University of Melbourne, as part of the ENA and API’s Australian Strategic Technology Program (ASTP).
