Abstract: A method and system for detecting operational irregularities in a thermal energy exchange system. Thermal energy exchange system comprises a first side, a second side and an interface between the first side and the second side. Heating/cooling is generated at the first side upstream to the interface, and heating/cooling is consumed at the second side downstream to the interface. The interface is provided by means of a plurality of substations connected to the first side and the second side, each substation being configured to facilitate thermal energy exchange between the first side and the second side. Measurement data indicative of one or more operational parameters of the first side is obtained, wherein the measurement data is collected by means of a measurement system. The measurement data is monitored so as to identify operational irregularities at the interface and/or the second side.

Abstract: A method of characterizing thermal energy distribution in a thermal energy exchange system using a data-driven model, the system having a thermal energy supply unit configured to supply heating/cooling, and a plurality of receiving units configured to consume heating/cooling supplied by said thermal energy supply unit. Connections of at least a subset of multiple receiving units to a primary supply line and a primary return line of the supply unit are modelled as respectively a single supply line and a single return line, wherein values indicative of temperature and flow rate of thermal energy exchange medium at the single supply line and the single return line are unknown to the data-driven model.

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.
