1. A computer implemented method for managing a distributed energy storage, DES, arrangement to participate in electric grid balancing, wherein the DES arrangement comprises a pool of nodes; the method comprising
detecting a balancing need for balancing the electric grid either in up direction or down direction;
selecting nodes for the balancing need, wherein the selection is based on randomly choosing nodes, using a logic in choosing the nodes and/or selecting the nodes based on properties of battery systems of the nodes;
identifying preferred balancing activity for a plurality of the selected nodes, wherein the preferred balancing activity is node specific, wherein first nodes have a preferred balancing activity in the same direction with the detected balancing need, and second nodes have a preferred balancing activity that is opposite to the detected balancing need;
starting activation of a balancing activity according to the balancing need for the first nodes upon detecting the balancing need; and
delaying activation of the balancing activity according to the balancing need for the second nodes wherein said delaying takes into account a required activation time of the detected balancing need.
