Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electric power is allocated to multiple regulating devices, then the total regulated power increases, but the variability in device performance increases due to deterioration
Solution Approach 1:
The system dynamically changes the allocation parameters (electric power distribution ratios) based on current device states and pre-stored correlation data. By adjusting these parameters according to each device's deterioration level, the system optimizes the balance between total regulated power and performance variability, resolving the contradiction between increasing power capacity and maintaining reliability.
2Power
If more regulating devices are used, then the capacity to regulate power increases, but the complexity of control increases
Solution Approach 1:
The system performs preliminary actions by pre-storing correlation information between device states, power allocation, and performance variability before actual operation. This advance preparation allows the control system to quickly determine optimal allocation without complex real-time calculations, thereby increasing regulation capacity while keeping control complexity manageable.
3Reliability
If electric power is allocated based on current device state, then performance variability is reduced, but the loss of time for data collection and processing increases
Solution Approach 1:
The system collects and stores correlation information in advance during periods when full data processing is feasible. This preliminary data collection and storage eliminates the need for time-consuming real-time analysis, allowing the system to quickly allocate power based on current device states while maintaining performance consistency and minimizing data processing time delays.

AI summary
A regulating-device-control system for controlling the operation of regulating devices for regulating the balance between electric power supply and demand includes: memory means storing, for each regulating device, correlation information expressing correlation of a state of the regulating device, an amount of power allotted to the regulating device, and an amount of variability in performance of the regulating device; determination means receiving state information that expresses the state of each regulating device and electric power information that expresses an amount of regulated power required for regulating the balance between electric power supply and demand, and, based on the correlation information, the state information, and the electric power information, determining the amount of electric power to be allotted to each regulating device such that the total value of the amount of variability in performance of each of the regulating devices is minimized under conditions in which the state of each regulating device is the state expressed by the state information and the total value of the amount of power to be allotted to the regulating devices is the amount of regulated power; and control means controlling the operation of each regulating device based on the determination result of the determination means.
