A method for controlling a power supply system

The invention relates to a method for controlling a power supply system having at least two power generators that are adapted to provide at least one form of energy to heat and / or cold and / or electrical energy. The power supply system further includes a controller for controlling each power generator of the power generator, and a control means for controlling the co-ordinated control equipment. The control means detects a power provisioning request for providing energy in the form of heat and / or cold and / or electrical energy and determined for each type of energy, which energy producers are required to meet the energy supply requirement. For each form of energy, the control means generates Einschaltforderungen for necessary for satisfying the energy supply requirement for energy producers and Ausschaltforderungen the unnecessary power generator. For each power generator, the controller determines whether one or more exists no Einschaltforderung and whether one is present, or no more Ausschaltforderung. is present for each power generator, for at least one Einschaltforderung, a Einschaltforderung is output to the corresponding control means and present for each power generator, for which no Einschaltforderung and at least one Ausschaltforderung, a Ausschaltforderung is output to the corresponding control device.
