Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing schedule determination devices often fail to properly determine operation schedules for energy-sourcing, energy-consuming, and energy-storing devices, particularly in scenarios where demand response signals require optimized energy management.
Innovation Solution
A schedule determination device comprising an acquisitor, a setter, and a determiner, where the setter narrows the range of variable values to establish constraint conditions for a new operation schedule, ensuring the device operates within optimized parameters to satisfy index constraints and minimize energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the range of variable values for constraint conditions is kept wide (first range), then the operation schedule has higher flexibility and adaptability, but the schedule determination becomes less precise and may not properly satisfy index constraints
Solution Approach 1:
The patent applies dynamics by making the variable range adaptive rather than static. The system dynamically adjusts the range of variable values based on the type of change detected in the operation schedule. For regular changes, a narrower second range is used to maintain precision, while for exceptional changes, the system can accommodate broader variations. This dynamic adjustment resolves the contradiction between flexibility and precision.
Solution Approach 2:
The patent changes the parameter of variable range width based on the change type. By detecting whether a change is regular or exceptional, the system adjusts the constraint condition parameters accordingly. This parameter change approach allows the system to maintain precision for routine operations while preserving adaptability for exceptional scenarios.
2Measurement precision
If the range of variable values is narrowed (second range) to improve schedule determination precision, then the operation schedule satisfies constraints more accurately, but the flexibility and adaptability of the schedule is reduced
Solution Approach 1:
The system dynamically selects between a narrow second range and broader constraints based on the detected change type. For regular changes, the narrow range ensures precision while maintaining sufficient flexibility. For exceptional changes, the system's change detection mechanism allows appropriate accommodation, thus resolving the trade-off between precision and adaptability.
Solution Approach 2:
The patent applies local quality by applying different range constraints to different types of changes. Instead of uniformly applying a narrow range to all scenarios, the system locally adapts the constraint strictness based on the specific change type detected. This allows precision where needed while preserving flexibility where appropriate.
3Productivity
If the operation schedule is determined using existing constraint ranges, then the determination process is simpler and faster, but the schedule may not properly reflect manual adjustments and incentive alignment
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple ranges (first range and second range) and their corresponding usage conditions. This preparation allows the system to quickly determine which range to apply based on the detected change type, maintaining fast processing speed while ensuring accurate and reliable schedule determination that reflects manual adjustments and incentive alignment.
Solution Approach 2:
The system uses feedback from the change detection process to select the appropriate variable range. By monitoring the type of change detected in the operation schedule, the system feedback-adjusts the constraint strictness, ensuring both rapid determination and high reliability in the resulting schedule.

AI summary
A schedule determination device includes an acquisitor, a setter, and a determiner. The acquisitor acquires indexes of an operation schedule of a device and constraint conditions of the indexes. The setter sets a second range, which is narrower than a first range set in the operation schedule before a change, as a range for values of variables that establish constraint conditions of indexes of a new operation schedule. The determiner determines the operation schedule of the device, using the variable values within the second range.
