METHOD FOR PROVIDING CONTROL POWER USING AN ENERGY STORE HAVING VARIABLE DEADBAND WIDTH WHEN 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 a function of a frequency deviation from a target frequency of the power network and/or absorbs energy from the power network. According to the invention, a deadband around the target frequency is specified, wherein the frequency deviation from the network frequency is measured with a higher accuracy than the width of the deadband, and a bandwidth is selected within the deadband as a function of a charging state of the energy store, wherein control power is provided outside the bandwidth. 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 or regulating the control 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 be drawn from the power network by the device.
