Abstract

The present invention relates to a method of controlling a multivalent energy supply system, wherein the multivalent energy supply system comprises at least two energy generators which use at least two different energy carriers to provide energy in the form of heat and/or cold and/or electrical energy. The energy supply system comprises, for each energy generator, a closed-loop controller for controlling controlled variables of the energy generator and a control device for coordinatedly controlling the closed-loop controllers. The control device detects at least one energy supply request for at least one energy form of heat and/or cold and/or electrical energy and determines a classification of the energy generator into groups according to a specific characteristic of the energy generators, each energy generator being assigned to exactly one group for each energy form that it provides. For each energy generator, the control device determines target values for meeting the at least one energy supply request depending on the classification of the energy generators into groups and outputs the target values to the closed-loop controllers.
