Abstract

Managing a distributed energy storage, DES, arrangement to participate in electric grid balancing, wherein the DES arrangement comprises a pool of nodes. The method is performed by detecting (301) a balancing need for balancing the electric grid either in up direction or down direction; selecting (302) nodes for the balancing need; identifying (303) preferred balancing activity for a plurality of the selected nodes, wherein the preferred balancing activity is node specific, wherein first nodes, if any, have a preferred balancing activity in the same direction with the detected balancing need, and second nodes, if any, have a preferred balancing activity that is opposite to the detected balancing need; starting activation (304) of a balancing activity according to the balancing need for the first nodes, if any, upon detecting the balancing need; and delaying activation (305) of the balancing activity according to the balancing need for the second nodes, if any.
