Abstract: An adaptive system for managing, in an integrated way, multiple EC with variable configuration, with prosumer and/or proconstomer and/or constorer nodes that are dynamically aggregated over the time, through a partitionable digital platform that includes logics for the automatic management. To each platform portion corresponds an EC and an oriented combination of logics in turn selected, sequenced and parametrized according to the optimization purposes provided by the EC, to locally implement, through the controller of each node, the commands imparted to its devices and optimize energy flows, by first adapting to EC logics and then to single node logics. The oriented combination is continually recalculated, within 50 milliseconds from the reading of the data of each aggregated node, to adapt in real time to the variable configuration of an EC and its nodes.
