Power Allocation Control for Area-Specific Carbon-Free Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technology struggles to allocate power generated without emitting carbon dioxide to specific areas within a facility, making it difficult for businesses to meet demands and miss out on business opportunities.
Innovation Solution
A power management method and apparatus that classifies power from multiple sources into categories based on carbon dioxide emissions, allocates this power to specific areas, and manages power usage to ensure that power generated without emitting carbon dioxide is prioritized in these areas, using a controller to manage and store power classifications and usage data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If power from multiple sources is mixed without classification, then power supply management is simple, but it becomes impossible to certify usage of carbon dioxide-free power in specific areas
Solution Approach 1:
The patent segments power from multiple sources into distinct categories (carbon dioxide-free power and carbon dioxide-emitting power) using virtual measurement meters. Each power source is individually identified and classified, allowing separate tracking and allocation to different areas. This segmentation preserves power classification information while maintaining manageable system complexity through structured organization.
Solution Approach 2:
The patent introduces virtual measurement meters as intermediary devices that do not physically measure power but logically classify and allocate power from different sources. These virtual meters act as mediators between physical power sources and consumption areas, enabling certification of power usage without adding physical measurement infrastructure.
2Reliability
If power allocation follows priority classification, then certification of carbon dioxide-free power usage is enabled, but power allocation complexity increases
Solution Approach 1:
The patent establishes priority classifications for different areas in advance, designating which areas should receive carbon dioxide-free power first. The power management apparatus pre-configures allocation rules based on area importance and environmental requirements, enabling automated real-time allocation without complex runtime decision-making. This preliminary setup ensures reliable certification while simplifying ongoing control operations.
3Adaptability or versatility
If all areas receive equal power allocation, then power distribution is simple, but specific areas cannot be guaranteed to receive carbon dioxide-free power
Solution Approach 1:
The patent applies different power allocation strategies to different areas based on their specific requirements. High-priority areas designated for carbon dioxide-free power consumption receive preferential allocation, while other areas follow standard allocation rules. This localized differentiation enables flexible adaptation to various area needs while maintaining overall system manageability through consistent classification frameworks.

AI summary
A power management apparatus manages the amount of power supplied to a plurality of areas. The areas include one or more areas for which a power classification to be used on a priority basis is determined. The power classification is determined based on the mode of carbon dioxide emissions during power generation. A controller of the power management apparatus executes processing including acquiring an amount of power supplied from each of a plurality of power sources, acquiring an amount of power used in each of the plurality of areas, allocating the amount of power supplied from each power source to each area based on the power classification to be used on a priority basis in the one or more areas and the amount of power used in each area, and storing the power classification and the amount of power allocated to each area.
