1Power

If wind farms are integrated into the electric power system to generate electricity, then electric power production is achieved, but variations in wind speed and direction cause fluctuations in power output leading to grid frequency variations and power delivery deficiencies

Engineering Contradiction:
Improveelectric power productionVSAvoidgrid frequency stability
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The system performs preliminary actions by generating meteorological forecasts and WTG availability predictions in advance of actual power generation. Multiple forecast algorithms process data ahead of time to predict future power output, allowing the grid to prepare for expected variations and maintain frequency stability through proactive scheduling and resource allocation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple wind turbine generators are congregated in a wind farm to increase power output, then electric power production increases, but the variability of individual turbines amplifies overall power delivery fluctuations

Engineering Contradiction:
Improveelectric power productionVSAvoidpower output consistency
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The system implements feedback by continuously monitoring actual power output from multiple WTGs and comparing it against forecasted values. The forecast algorithms are refined based on performance data and weather pattern analysis, creating a feedback loop that improves prediction accuracy over time and enables better coordination of turbine operations to smooth power delivery variations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system merges data from multiple sources including wide-area meteorological forecasts, narrow-area local conditions, and individual WTG availability status. By combining these diverse data streams through integrated algorithms, the system creates a comprehensive view of expected power output that accounts for both environmental factors and equipment status, enabling more stable aggregate power delivery.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If wide-area meteorological data is used for forecasting, then broad regional trends are captured, but site-specific local conditions are not adequately represented

Engineering Contradiction:
Improveforecast coverage areaVSAvoidlocal condition accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The system segments the forecasting approach by dividing it into two distinct levels: wide-area meteorological forecasting for broad regional trends and narrow-area local condition analysis for site-specific accuracy. Each level operates with appropriate algorithms and data resolution, and the results are integrated to provide both comprehensive coverage and precise local predictions for individual wind farms and turbines.

Inventive Principle:
Principle #1Segmentation
