Solution Overview

Problem

Uniform transmission of reverse power flow suppression messages to all facilities managed by a management server can lead to inefficient control, as it does not account for individual facility capabilities and conditions, potentially resulting in suboptimal suppression of reverse power flows.

Innovation Solution

A communication apparatus that transmits reverse power flow-power source information to a management server, allowing it to determine the capability and condition of each facility, enabling targeted and efficient control of reverse power flows by considering factors like power selling price, failure status, maintenance schedules, voltage, installation date, and disconnection information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If reverse power flow suppression messages are uniformly transmitted to all facilities, then the management server can simplify its control process, but the reverse power flow suppression efficiency deteriorates due to lack of individual facility considerations

Engineering Contradiction:
Improvecontrol process complexityVSAvoidreverse power flow suppression efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments the facility management into individual facility units, where each facility transmits its own reverse power flow-power source information independently to the management server. This allows the server to process and control each facility based on its specific characteristics rather than applying uniform control to all facilities, thereby improving suppression efficiency while maintaining manageable complexity through automated individualized processing

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by having each facility provide its specific reverse power flow-power source information (such as power selling price, failure status, maintenance schedules, voltage, installation date, and disconnection information), enabling the management server to apply customized control strategies tailored to each facility's local conditions and capabilities

Inventive Principle:
Principle #3Local quality

2Measurement precision

If the management server collects detailed reverse power flow-power source information from each facility, then the control precision improves, but the information processing complexity increases

Engineering Contradiction:
Improvefacility capability assessment precisionVSAvoidinformation processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having each facility pre-transmit its reverse power flow-power source information to the management server before control decisions are made. This advance provision of information allows the server to assess facility capabilities with high precision and prepare appropriate control strategies in advance, reducing the complexity of real-time processing while maintaining accurate facility-specific control

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by having each facility independently gather and transmit its own reverse power flow-power source information (including power selling price, failure status, maintenance schedules, voltage, installation date, and disconnection information) to the management server. This distributes the information gathering burden to individual facilities, reducing the processing complexity for the server while ensuring high precision and completeness of facility-specific data

Inventive Principle:
Principle #25Self-service

AI summary

A communication apparatus comprises a controller configured to control an output of a reverse power flow-power source that generates power for performing a reverse power flow from a facility to a power grid; and a transmitter configured to transmit reverse power flow-power source information about the reverse power flow-power source to a management server that transmits a power instruction message.
