  • Patent number: 11079729
    Abstract: A method is provided for controlling a multivalent energy supply system including at least two energy generators using at least two different energy carriers to provide heat, cold, and/or electrical energy. For each generator, a closed-loop controller controls variables of the generator. Each generator assumes one of three possible switching states: the generator must be switched on, must be switched off, or may be switched on or off. The system includes a control device for coordinatedly controlling the closed-loop controllers. The control device detects at least one request for heat and/or cold and/or electrical energy and determines whether a specific criterion is present which specifies exactly one of the three possible switching states for each generator. The control device determines target values for meeting the request depending on the request and the specific criterion and outputs the target values to the closed-loop controllers.

  • Publication number: 20200301381
    Abstract: The present invention relates to a method of controlling a multivalent energy supply system, wherein the 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. For each energy generator, there is a closed-loop controller for controlling controlled variables of the energy generator. Each energy generator can assume three possible switching states: the energy generator must be switched on, the energy generator must be switched off, or the energy generator may be switched on or switched off. The energy supply system includes a control device for coordinatedly controlling the closed-loop controllers. The control device is configured to detect at least one energy supply request for at least one energy form of heat and/or cold and/or electrical energy.

  • Patent number: 10784687
    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.

  • Patent number: 10782661
    Abstract: The present invention relates to a method of controlling a multivalent energy supply system comprising at least two energy generators which use at least two different energy carriers in order to provide energy in the form of heat and/or cold and/or electrical energy. The energy supply system further comprises a closed-loop controller for each energy generator 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. For each energy generator, the control device determines target values for meeting the at least one energy supply request based on the particular energy carrier being used, wherein the target values may also include instructions for switching the energy generator on or off, and outputs the target values to the closed-loop controllers.

  • Patent number: 10699352
    Abstract: The invention relates to a method of controlling an energy supply system comprising at least two energy generators each configured to provide at least one form of energy of heat and/or cold and/or electrical energy. The energy supply system further comprises one closed-loop controller per energy generator for controlling the energy generator and a control device coordinatedly controlling the closed-loop controllers. The control device detects an energy supply request for providing energy in the form of heat and/or cold and/or electrical energy and determines for each energy form which energy generators are required to meet the energy supply request. For each energy form, the control device generates switch-on requests for the energy generators required to meet the energy supply system and switch-off requests for the energy generators not required.

  • Publication number: 20190107295
    Abstract: The present invention relates to an apparatus for configuring a multivalent energy supply system. The apparatus comprises a memory device in which a base configuration is stored. The base configuration includes a plurality of 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, a flow through which a carrier medium flows which receives energy from the energy generators and transports it to a consumer circuit, and a return flow which receives the carrier medium coming from the consumer circuit. The base configuration further comprises a buffer storage which is arranged between the flow and the return flow. The energy generators within the base configuration may be arranged at positions in parallel to the buffer storage between the flow and the return flow and/or in series in the flow.
