The present invention relates to a method for determining a set of optimized control parameters (&#x398;) of a closed-loop controller () or an open-loop controller for an HVACR (heating, ventilation, air conditioning and refrigeration) system (). In a first method step, an outside temperature (T), an actual room temperature (T) of a room (), a supply temperature (T), a predefined target room temperature (T), and a predefined target supply temperature (T) are detected. From the detected measured values (T, T, T, T, T) and a time (t) of detection data packet (D) is generated, which is transmitted via an internet connection to a server () where the data packet (D) is stored in a storage medium () connected to the server (). In the next method step, a set of optimized control parameters (&#x398;) is calculated on the basis of the measured values (T, T, T, T, T) of the transmitted and stored data packet (D) and on the basis of measured values (T, T, T, T, T) of a plurality of further data packets (D) generated at an earlier time (t) of a specified period (&#x394;t) and/or at least one of a plurality of previously determined sets of optimized control parameters (&#x398;) by executing a calculation algorithm on the server (). In the following method step, the calculated set of optimized control parameters (&#x398;) is stored in the storage medium () connected to the server () and is transmitted via the internet connection to the closed-loop controller () or the open-loop controller of the HVACR system () or to a user (B) of the HVACR system ().

Method and device for internet-based optimization of parameters of heating control

The present invention relates to an energy management method for an energy system () in a building. The energy system () comprises a plurality of uncontrollable energy consumers (HH), at least one controllable energy consumer (WP), an energy storage device (BAT), a net connection point (NAP) through which energy can be drawn from the net and/or fed into the net, and a feedback-control or control device (EMS) which is designed to feedback-control or control the at least one controllable energy consumer (WP) and the energy storage device (BAT). The plurality of uncontrollable energy consumers (HH) is configured to draw energy from the net or from the energy storage device (BAT). The method comprises the following steps: detecting a current state of charge (SOC) of the energy store device (BAT), defining a period of time (&#x394;T) during which the uncontrollable energy consumers (HH) are supplied with energy from the energy storage device, determining a limit value (SOC) of the state of charge of the energy storage device (BAT) on the basis of a determined minimum energy demand of the plurality of uncontrollable energy consumers (HH) up to the time of charging (T), operating the at least one controllable energy consumer (WP) with energy from the energy storage device (BAT) if the current charge state (SOC) of the energy storage device (BAT) is greater than the determined limit value (SOC) of the charge state and operating the at least one controllable energy consumer (WP) with energy from the net if the current charge state (SOC) of the energy storage device (BAT) is less than or equal to the determined limit value (SOC) of the charge state.

Energy management method for an energy system and energy system

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.

Method for controlling a multivalent energy supply installation

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.

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 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.

Method for controlling a multivalent energy supply system

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. For each energy generator, the control device determines if one, several or no switch-off request is present and if one, several or no switch-off request is present. For each energy generator for which there is at least one switch-on request present, a switch-on request is output to the corresponding closed-loop controller and, for each energy generator for which there is no switch-on request and at least one switch-off request present, a switch-off request is output to the corresponding closed-loop controller.
