Abstract

A method for providing control power for an electricity network in which at least one energy store connected to the electricity network supplies energy to the electricity network as required and/or takes up energy from the electricity network as required, the control power being delivered in dependence on a frequency deviation from a setpoint value of a network frequency, a tolerance with respect to the frequency deviation being used to set a charging state of the energy store at a same time as providing the control power by the energy store. A device for carrying out such a method includes a control system and an energy store, the device being connected or connectable to an electricity network, the control system being connected to the energy store and controlling the control power that is given off and/or taken up by the energy store.
