Solution Overview

Problem

The high volume of similar messages generated by distributed energy generators, such as solar power systems, complicates real-time monitoring and analysis, reducing efficiency and making history reports cumbersome due to the large number of messages triggered by a single event or condition.

Innovation Solution

A method and system for aggregating messages from distributed generators, where a controller receives and correlates messages based on time parameters to generate summary messages, reducing the volume of data and improving monitoring efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each distributed generator sends individual messages for every event or condition, then real-time monitoring coverage is improved, but message volume increases making history reports cumbersome and analysis less efficient

Engineering Contradiction:
Improvereal-time monitoring coverageVSAvoidanalysis efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple individual messages from distributed generators into aggregated summary messages. When multiple DGs generate the same type of message within a predetermined time window, the controller consolidates them into a single aggregated message that includes the message type, count of affected DGs, and time window information, thereby reducing overall message volume while preserving monitoring coverage

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller performs preliminary aggregation of messages before they are stored or analyzed. By proactively grouping similar messages from multiple DGs into aggregated messages within predetermined time windows, the system prepares data in a more efficient format for subsequent history reports and analysis, reducing the processing burden beforehand

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If all messages are retained individually for history reports, then complete event records are preserved, but report complexity and data handling burden increase

Engineering Contradiction:
Improveevent record completenessVSAvoiddata handling complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent merges multiple individual messages from distributed generators into aggregated summary messages. When multiple DGs generate the same type of message within a predetermined time window, the controller consolidates them into a single aggregated message that includes the message type, count of affected DGs, and time window information, thereby reducing overall message volume while preserving monitoring coverage

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the message history into aggregated groups based on message type and time windows. Instead of storing every individual message separately, the system organizes them into segmented aggregated messages that group similar events, making history reports more structured and easier to navigate while retaining essential information about event frequency and scope

Inventive Principle:
Principle #1Segmentation

3Productivity

If message aggregation is implemented, then data handling efficiency is improved, but message processing complexity increases

Engineering Contradiction:
Improvedata handling efficiencyVSAvoidmessage processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The distributed generators themselves perform preliminary message filtering and categorization before sending messages to the controller. Each DG identifies its own message type and determines whether aggregation is applicable, reducing the processing burden on the central controller and distributing the computational workload across the distributed system

Inventive Principle:
Principle #25Self-service
