A power system for providing a grid service to a power grid, said power system comprising: an energy resource controller (ERC) adapted to monitor a state of charge (SOC) of at least one energy storage device (ESD), wherein said energy resource controller (ERC) adjusts in a normal operation mode (NM) a power supplied by the energy storage device (ESD) to said power grid (PG) or a power received by the energy storage device (ESD) from said power grid (PG) in response to grid parameters or remotely generated control signals to stabilize said power grid (PG), wherein if the monitored state of charge (SOC) of said energy storage device (ESD) exceeds an upper state of charge limit (SOC-H) the energy resource controller (ERC) connects in a power absorption mode (PAM) a power absorbing load (PAL) to said power grid as long as the grid parameters or remotely generated control signals indicate that power is to be removed from said power grid (PG).

Power system for providing a grid service to a power grid

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.
