RACE for Networks

Optimising Australia’s electricity grid through customer distributed energy resources and network integration

Our Themes

Program Leader: Ariel Liebman Ariel.Liebman@racefor2030.com.au

Purpose of project

This Opportunity Assessment project with synthesise knowledge from current industry activitiies and research into integration of EV’s into the grid. It will focus in particular on benefits and costs  of integration and identify and addressing the barriers as well as enablers EV  integration that leads to reduction in energy costs to consumers as well as reducing emissions. It will also Identify potential EV uptake pathways and commercialisation opportunities.

 

Impact of project

Large scale EV uptake will produce significant addition instantaneous demand on the grid if not optimised through either managed charging or V2G. Left unmanaged it could lead to short term reliability reduction at as little as 10% EV penetraton and leading to wholesale cost increases of up to 10% with only low power charging stations and a total increase in peak demand of as much sa 5 GW (10-15%). Alleviating these impact will cost in the $Billions. Managed charging if implemented fully can alleviate most of these impacts.

Purpose of project

This Opportunity Assessment will gather and combine the current state of knowledge and practice in improving the ability of electricity network operators to measure and observe the low voltage network to which PV and other DER connect. This is necessary in order to quantify and then improve the ability of these organisations to integrate larger numbers of DER’s into the grid.

 

Impact of project

With the 13,000 MW in 2020 of rooftop PV forecast to rise to more than 25,000MW by 2030, it is critical that this capacity is fully utilised. This will only be possible with successful outcomes in rolling out LV Network Visibility combined with hosting capacity enhancements. This will unlock significant value with even a 2% increase in hosting capacity providing consumer benefit of $50M/annum.

Purpose of project

In parts of the network, higher penetration of distributed energy resources (DER) is pushing voltages – that are traditionally set high – beyond the recommended thresholds. When voltages increase beyond the recommended levels, DER inverters can reduce their outputs or completely turn off, causing financial losses for the owners (i.e. curtailment). DER presents many opportunities and benefits to consumers and networks. However, there remains a limited evidence base regarding the extent and severity of DER curtailment in Australia, and its potential role in assisting network voltage management.
Improved understanding of curtailment can support the integration of higher levels of DER.

 

Impact of project

Quantify and improve our understanding of curtailment by studying a fleet of Virtual Power Plant (VPP) residential participants located in South Australia, and their inverter operation. Understand energy user perceptions of curtailment and fairness of curtailment.
