Method for providing control power by an energy store by using tolerances in the determination of the frequency deviation
First Claim
1. A method for providing control power, the method comprising:
- delivering the control power based on a frequency deviation from a setpoint value of a network frequency to discharge or change an energy store for supplying energy to an electricity network or taking up energy from the electricity network respectively, a charging state of the energy store being in one of (i) an upper charging state, (ii) a medium charging state, and (iii) a low charging state, amount of the charge in the medium charging state being less than amount of charge in the upper charging state and the amount of charge in the medium charging state being more than amount of charge in the low charging state, whereinthe delivered control power is varied within a tolerance with respect to the frequency deviation to discharge or charge the energy store to move the charging state toward the medium charging state.

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.
