Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If power generation curtailment is applied to RE power generators to minimize operating costs, then economic efficiency is improved, but power supply stability and regulation capacity may deteriorate

Engineering Contradiction:

Improveoperating costVSAvoidpower supply stability

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The system performs preliminary power generation predictions for RE power generators before curtailment decisions are made. By predicting future power generation outputs based on historical data and weather forecasts, the system can plan curtailment strategies in advance that minimize impact on power supply stability while achieving cost reduction goals.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback mechanisms where actual power generation data from RE generators is continuously monitored and fed back into the prediction model. This feedback loop allows the system to adjust curtailment plans dynamically, ensuring that stability constraints are maintained while optimizing economic efficiency.

Inventive Principle:

Principle #23Feedback

2Loss of energy

If power generation curtailment in RE power generators is increased to reduce operating costs, then economic efficiency is improved, but short-period regulation capacity and spinning reserve increase

Engineering Contradiction:

Improveoperating costVSAvoidshort-period regulation capacity

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts curtailment plans based on real-time weather conditions and power generation actuals. By making curtailment decisions flexible and adaptive rather than static, the system can maintain adequate regulation capacity and spinning reserve while minimizing operating costs.
