Solution Overview

Problem

Existing power interchange systems fail to maintain a balance between supply and demand, and do not ensure that power-transmitting and power-receiving apparatuses have the necessary control power for efficient power transfer, leading to inefficiencies and potential power interchange failures.

Innovation Solution

A power interchange management system that includes a communicating unit, a storage unit, and a computing unit to acquire and store information from power interchange apparatuses, forming groups based on configuration and power supply-demand state information, ensuring that each group has the necessary control power for power transmission and reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If power interchange is performed based on supply or demand requests without checking control power availability, then power transfer can be initiated, but the power interchange may fail due to insufficient control power at transmitting or receiving apparatuses

Engineering Contradiction:
Improvepower transfer efficiencyVSAvoidpower interchange success rate
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary checks to determine whether the power-transmitting apparatus and power-receiving apparatus have sufficient control power before initiating power interchange. This advance verification prevents failed power transfer operations by ensuring both apparatuses are ready to handle the control signals required for efficient power transmission.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The management server receives information from power interchange apparatuses about their control power status and uses this feedback to determine whether to permit or prohibit power interchange. This closed-loop control ensures that power transfer decisions are based on real-time system conditions and apparatus capabilities.

Inventive Principle:
Principle #23Feedback

2Reliability

If power interchange management checks control power availability for all apparatuses, then power interchange reliability is improved, but system complexity and communication overhead increase

Engineering Contradiction:
Improvepower interchange success rateVSAvoidmanagement system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A management server acts as an intermediary between power interchange apparatuses, centralizing the control power verification process. This mediator receives information from apparatuses, performs the necessary determinations about control power sufficiency, and issues permits or prohibitions for power interchange, simplifying the overall system architecture while maintaining reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The management server performs multiple functions including receiving information from power interchange apparatuses, determining control power sufficiency, and controlling power interchange permissions. This multi-functional approach consolidates complexity into a single centralized component rather than distributing it across multiple apparatuses.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If power interchange is permitted without verifying control power sufficiency, then system operation is simplified and faster, but power interchange failures occur due to lack of necessary control power

Engineering Contradiction:
Improvepower interchange operation simplicityVSAvoidpower interchange success rate
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Power interchange apparatuses automatically transmit information about their control power status to the management server without requiring manual intervention. The management server then automatically determines whether control power is sufficient and issues appropriate permissions, enabling the system to operate autonomously while ensuring reliability.

Inventive Principle:
Principle #25Self-service

AI summary

A communicating unit 113 of a power interchange management system 101 is coupled to a plurality of power interchange apparatuses 102 that control electrical equipment 131 to 133. Each power interchange apparatus is coupled via a system power supply line 160. A computing unit 117 creates a group for interchanging power by acquiring prescribed pieces of information 126 to 128 from the respective power interchange apparatuses and selecting a plurality of prescribed power interchange apparatuses based on the prescribed pieces of information. Prescribed conditions include a condition related to control power. The condition related to control power may be that a first power interchange apparatus on a power transmitting side has power for power transmission control necessary for transmitting power and, at the same time, a second power interchange apparatus on a power receiving side has power for power reception control necessary for receiving power.
