METHOD FOR PROVIDING CONTROL POWER USING AN ENERGY STORE HAVING VARIABLE DEADBAND WIDTH WHEN PROVIDING THE CONTROL POWER

A method providing control power for an electricity network in which at least one energy store supplies energy to the electricity network and/or takes up energy from the electricity network dependent on a frequency deviation from a desired frequency of the electricity network, a deadband being presc...

More Information
Summary:A method providing control power for an electricity network in which at least one energy store supplies energy to the electricity network and/or takes up energy from the electricity network dependent on a frequency deviation from a desired frequency of the electricity network, a deadband being prescribed around the desired frequency. The frequency deviation from the network frequency is measured with greater accuracy than a width of the deadband and a bandwidth within the deadband is chosen dependent on a charging state of the energy store, with control power being provided outside the bandwidth. A device carrying out the method includes at least one energy store and a control system controlling control power of the energy store in an open-loop or closed-loop manner, the energy store being connected to an electricity network such that energy can be fed into the electricity network and can be removed from the electricity network.
