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, tolerance with respect to the amount of the control power to be provided being used to set a charging state of the energy store at a same time as providing 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 control power given off and/or taken up by the energy store.

The present invention relates to a method for providing control power to stabilize an AC electrical grid, comprising an energy store which can take up and emit electrical energy, wherein for the purpose of providing the control power, the energy store is used together with a differential power provider, wherein the AC electrical grid operates at a predefined frequency and a frequency band around the predefined frequency is defined and the control power to be provided in the case of a frequency deviation within the frequency band is provided by the energy store to the extent of more than 50%, relative to the total control power to be provided.

Method for providing control power to stabilize an alternating current network, using an energy accumulator

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.

Method for providing control power using an energy store having variable deadband width when providing the control power

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.

A method for modification of a methane-containing gas stream, comprising the steps of: i) withdrawal of at least one substream from a methane-containing gas stream; ii) treatment of the substream with an electrically generated plasma, generating a modified gas composition which comprises a lower fraction of methane than the methane-containing gas stream used and iii) return of modified gas composition into the methane-containing gas stream. This method makes possible the storage of excess power in a natural gas line grid.

There are described thermoelectric elements that are manufactured by using a porous matrix or a porous substrate. The matrix consists of an electrically insulating material having sufficient thermal and chemical resistance as well as the lowest possible thermal conductivity, and is provided in predetermined regions with different thermoelectric materials, so that continuous conductors are formed in the matrix. These are electrically connected to one another to form thermocouples, which in turn are electrically interconnected with one another to form the thermoelectric element.
