Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power generation systems, accurately specifying the maximum suppliable power amount is challenging, especially during power shortages, which hinders effective demand response strategies.
Innovation Solution
A system comprising a system operator side computer and a power generation operator side computer that acquires and calculates the maximum suppliable power amount based on demand and weather data, and communicates power shortage notifications and incentives to consumers to manage power distribution efficiently.

Engineering Contradiction Analysis
1Productivity
If demand response is implemented to reduce power consumption during shortages, then power distribution efficiency is improved, but accurate specification of maximum suppliable power amount is required which increases system complexity
Solution Approach 1:
The system divides the power management function into separate modules: a supply amount acquirer that collects maximum suppliable power data from power generation operators, a demand specifier that determines power demand, and a shortage amount calculator that computes the difference. This segmentation allows each module to handle specific tasks independently, improving overall system efficiency without requiring complete system redesign.
Solution Approach 2:
The system introduces an intermediary computer system that acts as a mediator between power generation operators and demand management. This intermediary automatically acquires supply data, calculates shortages, and generates demand response requests, reducing the complexity burden on individual operators while maintaining accurate power amount specification.
2Measurement precision
If maximum suppliable power amount is accurately specified using multiple data sources, then demand response accuracy is improved, but information processing requirements increase
Solution Approach 1:
The system performs preliminary acquisition of maximum suppliable power amounts from power generation operators before the actual power shortage occurs. By collecting and storing this supply data in advance, the system reduces the information processing load during critical shortage periods while maintaining accurate power amount specifications through pre-processed data.
3Speed
If real-time power shortage calculation is performed, then demand response timeliness is improved, but computational requirements increase
Solution Approach 1:
The system calculates power shortage amounts in real-time by combining pre-acquired maximum suppliable power data with current demand specifications. This approach enables timely demand response calculations without requiring heavy computational resources, as the supply data is already available and only the difference calculation is performed in real-time.

AI summary
A system operator side computer includes: a supply amount acquirer configured to acquire a maximum suppliable power amount from a power generation operator at a predetermined time later; a demand specifier configured to specify a power demand at the predetermined time later; and a shortage amount calculator configured to calculate a power shortage amount based on the power demand and the maximum suppliable power amount.
