Enhanced flexibility with a variable speed power plant

This presentation focuses on the implementation of flexibility solutions for two variable speed pump turbine units with Doubly Fed Induction Machines (DFIM) in a pumped storage plant and their potential to enhance grid flexibility. It discusses operating range extension through hydraulic short circuit, improvement of the average annual overall efficiency, increase in performance by the implementation of synthetic inertia and FFR, and operation optimisation for the increase of maintenance intervals and minimised outage times.
