Abstract: A system or a method to at least partially steer systems, e.g. heating and/or cooling and clusters of systems, when the controller of the system is unknown or when the transfer function of the system is unknown. The steering of the energy flow, e.g. heating/cooling/electrical energy, includes providing energy to the system or the cluster of systems and preferably to manage common constraints, like capacity problems.

Abstract: A method and system that allows thermal energy to be supplied at different temperature levels to consumers, where each consumer is provided with its desired temperature whenever that is necessary. The method or a system for supplying consumers with heat energy or with cooling energy includes a set of three or more conduits for carrying a heat transfer fluid, each conduit carrying fluid at one of three or more different temperatures or temperature ranges, a plurality of heating and/or cooling consumer appliances distributed along the length of the conduits, each consumer appliance being linked to one of a plurality of pairs of conduits such that either: a consumer appliance is linked on a high temperature side, or a consumer appliance is linked on a low temperature side; a number of heat or cold generators, each pair of conduits being connected to at least one of the generators.
