ENERGY STORAGE SYSTEM

摘要

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).

1. An energy storage system, comprising one or more local energy storage systems with a respective local storage capacity and local output (LL) suitable for absorbing (En) and emitting (Ep) energy from and to connected power supply grid, with the one or more local energy storage systems each being connected to a non-local power supply grid and/or one or more local power supply grids, but at least comprising one local control unit, which is intended for control of the respective energy storage system for localized regulating and system tasks for the one or more respective local power supply grids and the energy storage system further comprising a central control unit connected via a communication network to the respective local control unit that is intended for control (SNL) of absorbing (En) and emission (Ep) of energy from the one or more local energy storage systems to the non-local power supply grid, with the central control unit being equipped for disposing of all portions of the local storage capacities (LSKg) and of the local output (LLg) of the one or more energy storage systems for non-localized regulating and system tasks (NLRS) in the non-local power supply grid that have been submitted by the respective local control units to the central control unit via the communication network as not needed for the localized regulating and system tasks (LRS).
