| description | An arrangement for receiving electrical energy from a power grid and for discharging electrical energy to the power grid comprises: a converter to convert from AC to DC and vice versa and a control device. The converter includes: a power unit connected on one side to a DC I/O and on another side to an AC I/O; an energy storage device; an energy-converter; and a changeover mechanism to which the energy storage device or the energy-converter is connected via the DC I/O. The control device controls the changeover mechanism such that a neutral state is a state of charge of the energy storage device between 50% and 100%; and at or above the neutral state, the changeover mechanism connects the DC I/O of the converter to the energy-converter at a network frequency higher than a nominal network frequency plus a predetermined, non-zero amount. |
