Solution Overview
Problem
Existing energy supply systems face challenges in efficiently managing multiple energy generators providing heat, cold, and electrical energy, leading to uneven durability and operational safety due to frequent switching operations and conflicting demand requirements.
Innovation Solution
A method of controlling an energy supply system using a control device that coordinates closed-loop controllers to determine necessary energy generators for demand, prioritizing switch-on and switch-off requests based on 'on before off' and 'on before off' rules, and dynamically adjusting priorities to optimize generator utilization and reduce switching operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple energy generators are operated to meet diverse energy demands, then the system can provide heat, cold, and electrical energy simultaneously, but the frequency of switching operations increases leading to reduced durability
Solution Approach 1:
The control device dynamically adjusts the operational status of energy generators based on real-time demand requirements. It evaluates switch-on and switch-off requests for each generator, considering the current energy demands (heat, cold, electrical) and determines the optimal configuration. This dynamic control ensures that generators are switched only when necessary, reducing unnecessary switching operations while maintaining the system's ability to meet diverse energy demands.
Solution Approach 2:
The control device receives feedback from demand requirements and generator status, then adjusts the operational configuration accordingly. By continuously monitoring the energy demands and the current state of generators, the control device can make informed decisions about switching operations, thereby optimizing both the adaptability to meet diverse demands and the durability by minimizing unnecessary switching.
2Adaptability or versatility
If energy generators are switched on and off frequently to meet changing demand, then the system can adapt to varying energy requirements, but the operational safety and reliability decrease
Solution Approach 1:
The control device implements dynamic control by evaluating both switch-on and switch-off requests for each energy generator based on current demand requirements. It determines the optimal operational configuration by considering the interplay between multiple generators and diverse energy demands, enabling the system to adapt to varying requirements while maintaining operational safety through controlled and necessary switching operations only.
Solution Approach 2:
The control device uses feedback from the system state and demand requirements to adjust generator operations. By monitoring the current configuration and energy demands, it can determine when switching is truly necessary, thereby maintaining operational safety while responding to changing demands.
3Productivity
If the system coordinates multiple closed-loop controllers, then the control precision and efficiency improve, but the system complexity increases
Solution Approach 1:
The control device merges the control functions for multiple energy generators into a single coordinated system. Instead of having independent controllers for each generator, the control device centrally manages switch-on and switch-off requests for all generators, evaluating them together based on overall demand requirements. This merging approach improves system efficiency through coordinated control while managing complexity by providing a unified control interface.
Solution Approach 2:
The control device serves multiple functions: it monitors energy demands (heat, cold, electrical), evaluates switch-on and switch-off requests for multiple generators, determines optimal configurations, and coordinates the operational status of all generators. This multi-functional approach improves productivity by handling all control tasks in a single device while managing system complexity through integration.

AI summary
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.
