Description

Australia’s energy markets are in a period of rapid change, driven by the growth of distributed energy resources (DERs) like renewable energy generation and energy storage technologies. As decarbonisation of Australia’s electricity grid continues, these changes will have a large impact on the network, introducing complexity and challenges regarding supply-demand, load balance, and power flows from distribution systems to the central transmission system. Neighbourhood, or community-scale, batteries (~1-5MW) present an opportunity to mitigate these challenges, deferring the need for network upgrades by providing local energy storage and distribution. Using the shared battery, communities can store energy from their rooftop solar PV, allowing for increased solar PV energy generation (hosting capacity), lower energy costs, and greater energy equity across solar and non-solar energy users.

The impact of neighbourhood batteries can differ significantly depending on the models used to optimise its operation for techno-economic objectives like maximizing owner profits, minimizing customers costs, managing voltage, and maximizing decarbonisation. To ensure neighbourhood batteries positively contribute to the renewable energy transition, decarbonisation algorithms need to be carefully written to optimise how the battery stores local energy and energy from the National Electricity Market (NEM). Factors that need to be considered include the battery’s charging/discharging cycles, time and duration of use, and emissions reduction factors associated with replacement of fossil-fuel powered energy generation in the NEM.

The research outcomes of this project will contribute to the work being conducted for the NBI. The NBI addresses the need for data-driven evidence about the impacts of neighbourhood batteries on decarbonisation, prices and economics, access and equity, and hosting capacity for local renewables. In doing so, it seeks to provide guidance on models for optimisation of these criteria, producing the necessary impact, software, and integration tools to do so.
