Powerlink Cost-Effective System Strength Study

closed

The Powerlink Cost-Effective System Strength Study will promote increased awareness of system strength and measures that can be used to manage it, including centralised and coordinated solutions.Key resultsThis study has shown that grid forming batteries can play a constructive role enabling renewables and supporting the operation of the power system. The study has shown that a 100 MW battery can support the connection of 300 MW of inverter based generation. These results are specific to the particular case examined and care should be taken not to apply the outcomes to other situations However, similar to any dynamic device (including synchronous condensers) they are not a ‘silver bullet’ and to be effective, there are a range of factors which need to be carefully considered. The thoughtful deployment of grid forming batteries alongside other technologies and techniques will be critical to managing the transition to renewables.
