US 10,699,352 B2 · Method for controlling a power supply system

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. 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.

A method of controlling an energy supply system, the energy supply system including at least two energy generators (E1-E5, B1-B2, G1-G2, H1-H2) that are each configured to provide at least one energy form of heat (F1) and/or cold (F3) and/or electrical energy (F2) and at least one of which is configured to simultaneously provide at least two forms of energy (F1-F3), at least two closed-loop controllers (R1-R5) that each control a respective one of the energy generators (E1-E5, B1-B2, G1-G2, H1-H2), and a control device (S) for coordinatedly controlling the closed-loop controllers (R1-R5), the method comprising the steps of:

detecting an energy supply request (EA) to provide energy in the form of heat (F1) and/or cold (F3) and/or electrical energy (F2);
for each energy form (F1-F3), determining which energy generators (E1-E5, B1-B2, G1-G2, H1-H2) are required to meet the energy supply request (EA);
for each energy form (F1-F3), generating switch-on requests (ON) for the energy generators (E1-E5, B1-B2, G1-G2, H1-H2) required to meet the energy supply request (EA) and generating switch-off requests (OFF) for the energy generators (E1-E5, B1-B2, G1-G2, H1-H2) not required to meet the energy supply request (EA);
for each energy generator (E1-E5, B1-B2, G1-G2, H1-H2), determining if one, several or no switch-on request (ON) is present;
for each energy generator (E1-E5, B1-B2, G1-G2, H1-H2), determining if one, several or no switch-off request (OFF) is present;
for each energy generator (E1-E5, B1-B2, G1-G2, H1-H2) for which there is at least one switch-on request (ON) present, outputting the switch-on request (ON) to the corresponding closed-loop controller, and, for each energy generator (E1-E5, B1-B2, G1-G2, H1-H2) for which there is no switch-on request (ON) and at least one switch-off request (OFF) present, outputting the switch-off request (OFF) to the corresponding closed-loop controller;
or
for each generator (E1-E5, B1-B2, G1-G2, H1-H2) for which there is at least one switch-off request (OFF) present, outputting the switch-off request (OFF) to the corresponding closed-loop controller and, for each generator (E1-E5, B1-B2, G1-G2, H1-H2) for which there is no switch-off request (OFF) and at least one switch-on request (ON) present, outputting the switch-on request (ON) to the corresponding closed-loop controller;
determining a first energy generator (E1) configured to simultaneously provide a first energy form (F1-F3) and a second energy form (F1-F3) for which a switch-on request (ON) of the first energy form (F1-F3) and a switch-off request (OFF) of the second energy form (F1-F3) is present;
determining a second energy generator (E2) configured to provide the second energy form (F1-F3) for which a switch-on request (ON) of the second energy form (F1-F3) is present;
generating a switch-on request (ON) of the second energy form (F1-F3) for the first energy generator (E1);
and
generating a switch-off request (OFF) of the second energy form (F1-F3) for the second energy generator (E2).
