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.

Arrangement comprising an energy storage device for receiving electrical energy from an electrical network and discharing electrical energy to the electrical network

Circuit assembly (), uninterrupted power supply unit () with converter part () and converter unit (), central control unit () and input for current to be converted and output for converted current and circuit part () connected upstream of input of converter part or connected downstream of output of converter part, external control unit () connectable to circuit assembly and central control unit () configured to receive control instructions from external control unit (). Circuit assembly can be disconnected from the power supply network rapidly and without repercussions on the network. Every circuit part () comprises a decentralized control unit (), connected to central control unit () via communication bus (), receiving control instructions from central control unit (). External control unit () is connected to communication bus () and decentralized control unit () is configured to receive control instructions from external control unit ().
