METHOD FOR PROVIDING CONTROL POWER WITH AN ENERGY STORE USING TOLERANCES IN DETERMINING THE FREQUENCY DEVIATION

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, the control power is generated as a function of a frequency deviation from a target value of a network frequency, wherein the tolerance with respect to the frequency deviation is used in order to adjust the charging state of the energy store simultaneously with the provision of the control power by the energy store. The invention also relates to a device for carrying out such a method, in which the device comprises a control and an energy store, wherein the device is or can be connected to a power network, the control is connected to the energy store and regulates the control power released by and/or absorbed by the energy store.
