Abstract: An energy storage module is provided for reversibly storing electrical energy in the form of mechanical rotation energy. The energy storage module comprises a plurality of flywheel storage units, at least one control system and at least one module control unit, wherein the flywheel storage units are connected electrically in parallel by means of a common DC voltage intermediate circuit, and the control system or systems is/are connected to the common DC voltage intermediate circuit by way of the respective output side and to at least one external voltage grid by way of the respective input side, wherein the module control unit is provided for transmitting suitable prespecified torques to the flywheel storage units for emitting or absorbing energy to/from the DC voltage intermediate circuit, and at least one of the control systems is designed to control the DC voltage in the DC voltage intermediate circuit.

Abstract: An energy storage system is provided with one or more local energy storage systems and a procedure to operate such an energy storage system. The local energy storage systems are connected to a non-local power supply grid and/or one or more local power supply grids each compromising at least one local control unit, which is intended at least for control of the respective energy storage system for localized regulating and system tasks (LRS) for the one or more respective local power supply grids. The energy storage system furthermore comprises a central control unit connected via the communication network to the respective local control units, which is intended for control (SNL) of absorbing (En) and emitting (Ep) energy of the one or more local energy storage systems to the non-local power supply grid, with the central control unit being equipped to dispose of all portions of the local storage capacities (LSKg).

Abstract: A mobile energy storage module is provided having a high energy storage capacity and output. An energy storage system having such energy storage modules and to a method for adjusting the energy storage system to the demands in the power supply grids is also disclosed. To achieve this, the mobile energy storage module comprises an enclosing module housing having at least one power connection interface and at least one data interface, and additionally comprises a flywheel module having a plurality of flywheel energy storage units, a vacuum module for generating a minimum vacuum required for operating the flywheel module, a cooling module for removing at least internal thermal loads during operation of the flywheel module, and a module control system that is configured to appropriately control the modules in the module housing.
