Project results
FLEXHYBAT is expected to be completed by 2026. While the project is still in progress, files for dissemination of results will be made available on this page gradually.
BESS to increase the RUL of the runner
The hybridisation of the pump-turbine with the battery will reduce stress peaks caused by rapid load changes and frequency regulation stages in the runner, thereby increasing its remaining useful life.
BESS to increase the RUL of the driving mechanism
The hybridisation with the battery will also reduce wear and tear on the guide vanes by decreasing the number of opening-closing cycles during frequency regulation and load changes, increasing their remaining useful life.
Second-life Li-ion batteries modelling
Battery modeling is being carried out after extensive cells characterization in the laboratory. Equivalent circuit model parameters have been determined for different ambient and operating conditions.
The obtained cell model has been extended to battery pack level with Simscape software.
BESS providing fast ramp-up services and flexibility
A power change in a hydropower turbine causes an initial output power reduction due to water inertia in a penstock. By using a specifically programmed BESS, this power drop is attenuated.
Evaluation of the BESS in innovative applications
