Abstract: The invention essentially relates to a facility for charge current control of storage units in an electrical energy supply grid including, among others, distributed generators and distributed storage units, in which a logic unit is present such that, a storage charge current value can be determined for the storage unit as a function of control variables transferred via a communication system of measurement variables determined at the storage and of locally held internal control variables. This represents an important component for achieving the optimum possible overall utilization of the distributed and multiple-use energy storage.

Abstract: An energy management system of a power supply grid includes at least one control unit (CU) connected to distributed energy resource controllers (ERC) of energy resources (ER) of the power supply grid by means of a communication network, (CNW) wherein the control unit (CU) monitors communication links (CL) between the control unit (CU) and the energy resource controllers (ERC) via the communication network (CNW), and wherein the control unit (CU) is adapted to calculate a predicted operation behavior of an energy resource (ER) controlled by an energy resource controller (ERC) if a loss of communication or a communication bandwidth limitation of the monitored communication link to the energy resource controller (ERC) is detected.

Abstract: Method and apparatus for performing a local control of an energy resource An energy resource controller (ERC) of an energy resource (ER) within an energy management system of a power supply grid (PSG), wherein said energy resource controller (ERC) is adapted to monitor a communication link (CL) to a control unit (CU) of said energy management system and to emulate after a loss or limitation of communication via said communication link (CL) has been detected a continued reception of control parameters and/or control limits from said control unit (CU) to perform a local control of the associated energy resource (ER) on the basis of the emulated control parameters and/or control limits according to an applied energy management policy (EMP).
