Advanced VPP Grid Integration

closed

The Advanced VPP Grid Integration project aims to show how higher levels of energy exports to the grid from customer solar and battery systems can be enabled through dynamic, rather than fixed, export limits, and to test the value this can create for customers and Virtual Power Plant (VPP) operators.Key resultsSA Power Networks and Tesla have co-designed an Application Programming Interface (API) that enables the secure real-time exchange of data between Tesla’s and SA Power Networks’ systems via the internetTesla has successfully operated their VPP at exports exceeding their previous static limit of 5kW per site while maintaining compliance with the limits received via the API across a variety of network conditionsIt was found that time-varying and locational export limits could enable DER to be hosted at higher levels of penetration, particularly distributed energy storage VPPs conducting arbitrage between solar and non-solar hoursThe results support the view that a dynamic network capacity management approach can enable larger, more active DER and demand management systems to continue to operate under higher levels of DER penetration than would otherwise be possible with static limits.
