Computer-implemented method for managing distributed energy storage system

A computer-implemented method for managing a distributed energy storage system comprising a plurality of nodes coupled to a power grid, wherein each node comprises at least one energy storage, the method comprising:

• receiving an activation signal for power grid frequency balancing comprising a frequency balancing capacity requirement;
• selecting nodes out of the plurality of nodes to be activated and/or deactivated for the power grid frequency balancing according to the frequency balancing capacity requirement;
• activating and/or deactivating the selected nodes for the power grid frequency balancing;
• monitoring during the power grid frequency balancing, whether a power quantity of the selected nodes deviates from the frequency balancing capacity requirement, wherein the power quantity is based on a measurement of the at least one energy storage of each node in the selected nodes;
• and
• in response to the power quantity deviating from the frequency balancing capacity requirement, reselecting nodes out of the plurality of nodes to be activated and/or deactivated for the power grid frequency balancing according to the frequency balancing capacity requirement.
