Solution Overview

Problem

Conventional methods for managing electrical loads result in low utilization rates of power supply devices, low power consumption efficiency, and a high likelihood of overload trips due to static allocation and manual power rationing, which limits the reallocation of idle capacity and fails to effectively manage rapid changes in load demand.

Innovation Solution

A method and apparatus for dynamically controlling electrical loads through intelligent electricity monitoring and metering, where a mobile terminal acquires current capacity balances and requests adjustments from a regional coordination control apparatus or server to ensure sufficient capacity for starting electric consumption devices, thereby determining whether to allow device startup based on the adjusted capacity balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If static allocation and manual power rationing are used, then system complexity is reduced, but power consumption efficiency deteriorates and utilization rate of power supply devices decreases

Engineering Contradiction:
Improvesystem complexityVSAvoidpower consumption efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system enables automatic capacity balance acquisition, automatic comparison with load power requirements, and automatic startup control of electric consumption devices. The intelligent electricity monitoring and metering terminal autonomously performs capacity management without manual intervention, achieving self-service operation that improves power consumption efficiency while maintaining manageable system complexity through automated rule-based decision-making.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If static allocation is used, then ease of operation is improved, but utilization rate of power supply devices deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidutilization rate of power supply devices
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements dynamic capacity allocation by continuously acquiring current capacity balance from the intelligent electricity monitoring and metering terminal and comparing it with the load power of electric consumption devices. The system dynamically adjusts capacity allocation based on real-time conditions, allowing users to start devices when capacity is sufficient while automatically managing peak load periods, thereby improving utilization rate without compromising ease of operation.

Inventive Principle:
Principle #15Dynamics

3Productivity

If demand-side management is used, then power consumption efficiency is improved, but device complexity deteriorates due to excessive user participation requirements

Engineering Contradiction:
Improvepower consumption efficiencyVSAvoidinfrastructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The intelligent electricity monitoring and metering terminal serves as an intermediary that automatically manages capacity balance between power supply and demand. Instead of requiring direct user participation and complex demand-side management infrastructure, the system uses the terminal to autonomously acquire capacity balance, compare it with load requirements, and control device startup, thereby improving power consumption efficiency while reducing infrastructure complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If total capacity limiting is used, then reliability is improved by preventing overload trips, but productivity deteriorates due to single-manner load control

Engineering Contradiction:
ImprovereliabilityVSAvoidpower utilization flexibility
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the load control approach by focusing on individual electric consumption devices rather than applying uniform total capacity limiting. The system acquires current capacity balance, compares it with the specific load power of each device to be started, and makes device-specific startup decisions. This segmented approach prevents overload trips while maintaining power utilization flexibility, as users can start devices when capacity permits without blanket restrictions.

Inventive Principle:
Principle #1Segmentation

AI summary

Provided are a method and apparatus for dynamically controlling electrical loads, a storage medium and an electronic apparatus. The method includes that: a current capacity balance of a user sub-region is acquired from an intelligent electricity monitoring and metering terminal through a mobile terminal; when the current capacity balance is smaller than a load power of an electric consumption device to be started in the user sub-region, a regional coordination control apparatus or a server is requested through the mobile terminal to adjust and increase a capacity allocated for the user sub-region, such that a capacity balance will be greater than or equal to the load power; and whether to allow to start the electric consumption device is determined according to a decision replied by the regional coordination control apparatus or the server.
