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:
The invention substantially relates to a method, wherein operational control parameters and/or control limits, which are to be conveyed using communications technology, are determined on the operator side for each of the distributed storage devices in such a way that a specific cost function is minimal for all of the distributed storage devices on the basis of locally measured variables determined at the respective storage device and transmitted to the operator and on the basis of installation-dependent control limits stored locally in each case and which are also transmitted to the operator, and wherein the operational control parameters and/or control limits, which are to be conveyed using communications technology, are transmitted from the operator side to the corresponding distributed storage devices and implemented there. Consideration of the locally limited available energy and power and the boundary conditions resulting from serving multiple applications from one storage device hereby ensures power availability and, by way of example, an optimal overall service life of all distributed storage devices.
