Abstract: A storage unit for a consumer is described, having an energy storage in which electric energy can be stored, and a current interface via which the storage unit can be connected to an electricity grid. The storage unit furthermore has a circuit arrangement which is arranged between the energy storage and the current interface in the direction of current flow, and a control interface for controlling the storage unit. The storage unit is controllable only via the control interface which communicates only with an external control. A storage system and a method of controlling a storage system are furthermore described.

Abstract: A storage unit for a consumer is described, comprising an energy storage in which electrical energy can be stored. The storage unit has a current interface via which the storage unit can be connected to an electrical grid. Furthermore, the storage unit comprises a circuitry positioned between the energy storage and the current interface in the direction of current flow, and a server unit which is configured to set up a decentralized computing network along with further server units, by means of which transactions are managed, controlled and/or monitored in a decentralized manner. A storage system is furthermore described.
