Evaluating Various Battery Behaviours to Maximise Consumer Value Across the Electricity Supply Chain

Distributed Battery Energy Storage Systems (BESSs) have the potential to impact every link of the power supply chain. Analysing the impact of different BESS behaviours enables policymakers to design transactive energy markets that maximise the overall value provided by distributed BESSs and minimise the cost of electricity supply for consumers. This paper documents analysis conducted within the Australian state of Queensland. The results show that optimising the behaviour of BESSs for local conditions can consistently provide benefits up the supply chain. Conversely, BESS behaviours optimised for a higher level of the supply chain (such as the state-wide level) do not reliably support lower levels of the supply chain. Thus, the analysis concludes that the overall value of BESSs are maximised when the market and tariff design incentivises behaviour that supports very local conditions.
