Factory Power-Outage Planning for Multi-Factory Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing power failures in factories restrict operations and may fail to maintain power supply within a feasible range, leading to potential factory shutdowns and inefficient power selling strategies.
Innovation Solution
A guidance device and method that calculates a safety operation plan for multiple factories, determining a combination of operating and non-operating factories to ensure power consumption falls within a sustainable range, considering constraints such as power demand, grouping, and minimizing operational state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation of a specific factory is controlled to fall within the power supply range, then power supply stability is improved, but the operation of the factory is significantly restricted
Solution Approach 1:
The system segments the factory portfolio into multiple groups (Group A: factories to operate, Group B: factories to stop operating, Group C: other factories) and calculates optimal combinations within Group C while maintaining Group A operations. This segmentation allows the system to maintain power supply stability by controlling overall power consumption while preserving operational flexibility through selective factory operation decisions.
2Reliability
If the operation of a specific factory is controlled to fall within the power supply range, then power supply stability is improved, but it may fail to fall within the range only by controlling the specific factory
Solution Approach 1:
The system merges the operation control of multiple factories into a coordinated system. By calculating optimal combinations of operating and non-operating factories across different groups, the system achieves power supply stability through multi-factory coordination rather than isolated control, thereby maintaining reliability while managing complexity through systematic combination calculation.
3Loss of energy
If the factory is stopped to prioritize power selling, then power selling revenue is improved, but the factory operation is reduced
Solution Approach 1:
The system dynamically determines factory operation status based on power price conditions and power supply-demand balance. By calculating optimal combinations that consider both power selling opportunities and operational requirements, the system adaptively adjusts factory operations to maximize revenue while maintaining necessary production levels, rather than applying static stop/start decisions.
4Stability of the object's composition
If the number of times of changing operation state of factories is reduced, then operational stability is improved, but the responsiveness to power price changes is reduced
Solution Approach 1:
The system performs preliminary calculation of optimal factory combinations considering future power price trends and supply-demand conditions. By pre-calculating operation plans that balance stability and adaptability, the system can respond to power price changes more effectively while minimizing unnecessary operation state changes, as the calculations account for both current and future conditions.

AI summary
A guidance device selects a safety factory operating at a time of a power failure, and presents a safety operation plan for a plurality of factories in a power system, and includes a presentation unit configured to calculate a combination of an operating factory and a non-operating factory within a predetermined period from a planned value of power demand-supply of the factories such that a power consumption amount of the factories satisfies a predetermined condition, and present information on the calculated combination.
