Distributed energy resourcesProject Optimal DER Scheduling for Frequency Stability
This study documents the findings of University of Tasmania’s investigation into how to optimally schedule DER to provide low-cost frequency stability services within distribution network constraints.
As wind and solar replace conventional generation, the critical function that conventional synchronous machines play in keeping frequency stable in our power systems is being removed. Distributed Energy Resources (DER) have the potential to provide frequency support, thus enabling higher levels of renewables. This opportunity is particularly evident in Australia, which has a high and increasing uptake of distributed generation and storage. However, extracting this capability without violating limits of distribution networks will become a significant challenge as the penetration of DER in networks increases.
