Sliding-Mode Control Tames Oscillations in Grid-Forming Battery Storage
Researchers from Hainan Power Grid and Tsinghua University demonstrated that replacing the conventional current regulator with an integral sliding-mode controller eliminates low-frequency oscillations in grid-forming battery storage. This finding is critical for engineers designing stable control strategies for BESS projects that must interface with high short-circuit-ratio grids.
Solar Smoothing Batteries Face Steep Operating Declines in Available Power
A detailed engineering study reveals that battery systems providing solar ramp firming and state-of-charge recovery deliver significantly less upward reserve than nameplate ratings suggest. This finding is critical for developers and grid operators to accurately model available capacity and avoid overestimating the operational value of hybrid solar-storage assets.
Spain: Regional Government Gives Environmental Approval to 70 MWh Battery Plant in Medina del Campo
The Government of Castilla y León has issued a favorable environmental impact report for the 70 MWh BESS El Carrascal project in Medina del Campo. This regulatory milestone allows the administrative processing of the battery storage facility to proceed, which is critical for developers integrating storage with existing solar assets to enhance grid management.
Belgium: Flanders Counts Nearly 200,000 Home Batteries and Almost 2 Gigawatt-Hours of Storage Capacity
Fluvius data reveals that Flanders has installed nearly 200,000 home batteries with cumulative storage capacity approaching 2 gigawatt-hours. This rapid expansion highlights the critical role of residential storage in managing grid stability and self-consumption within the European energy transition.
Australia: Williamsdale Battery Starts Operation at 500 MWh
The Williamsdale battery has been commissioned, marking the completion of the utility-scale component of the Big Canberra Battery program. This milestone provides a tangible asset for evaluating the performance and revenue potential of large-scale battery storage in the Australian Capital Territory.
