METHOD FOR PROVIDING CONTROL POWER WITH AN ENERGY STORE USING TOLERANCES AT THE TIME OF PROVIDING THE CONTROL POWER

摘要

The invention relates to a method for providing control power for a power network, in which at least one energy store connected to the power network supplies energy to the power network as necessary and/or absorbs energy from the power network as necessary. According to the invention, and in the event of a change of the required control power, the time following the change, after which a modified control power is provided by the energy store, is selected as a function of the actual charging state of the energy store. The invention also relates to a device for carrying out such a method, in which the device comprises at least one energy store and a control for controlling and/or regulating the power of the energy store, wherein the energy store is connected to a power network such that energy can be supplied to the power network and drawn from the power network by the device.
