Solution Overview

Problem

Ancillary service providers in electric grids face inefficiencies due to complex systems, leading to inaccurate tracking of incoming command signals, which affects precision and revenue generation.

Innovation Solution

A compensation equation is developed through regression analysis of performance data and programmed into a resource controller to adjust incoming signals, mitigating system non-idealities and improving resource response precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a resource system participates in ancillary services in an electric grid, then revenue generation is enabled, but system delays and non-idealities cause inaccurate tracking of incoming command signals, reducing precision

Engineering Contradiction:

Improveprecision of resource response trackingVSAvoidsystem delays

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary characterization of its own response behavior by capturing performance data and developing a compensation equation through regression analysis. This pre-computed model is then used to adjust incoming signals in real-time, compensating for known system delays and non-idealities before they affect tracking accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses captured performance data as feedback to develop a compensation equation that models the relationship between incoming signals and actual resource response. This feedback loop allows the system to identify and correct for its own delays and non-idealities, improving precision without adding physical complexity.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If the resource system adjusts its response to improve tracking precision, then performance scores improve, but the system complexity increases due to compensation modules and regression analysis

Engineering Contradiction:

Improveresource response precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The compensation equation acts as a mathematical intermediary between the incoming control signals and the resource system's actual response. Rather than physically modifying the resource system, the intermediary model compensates for non-idealities by adjusting the interpretation of incoming signals, achieving precision improvement without physical complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces physical modifications or hardware complexity with a computational approach. By using regression analysis and mathematical compensation equations, the system achieves precision improvement through software-based signal adjustment rather than mechanical or physical system modifications.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
