A power transfer system includes a first branch including a controlled switch and a second branch including a variable frequency converter, in parallel between an AC network and a reversible pump-turbine, the variable frequency converter includes: a first AC/DC converter having a first DC interface, and a second AC/DC converter having a second DC interface, the first and second DC interfaces being connected by a DC link, a control circuit having a first mode wherein it simultaneously opens the switch and it transfers electrical power until it reaches the same frequency on two AC interfaces, and having a second mode wherein it closes the switch of the first branch; an energy storage system; and a switching system for selectively connecting the energy storage system to the DC link.
