Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wind farms face challenges in consistently providing committed power due to uncontrollable wind variations, leading to increased costs through supplementary energy storage or purchasing power from neighboring generators.
Innovation Solution
A multi-farm wind power dispatch management system that includes wind turbine dispatch controllers, wind farm dispatch management systems, and a master dispatch management system to receive and aggregate operating parameters, compute real-time output power, and generate reference commands to control operating parameters and dispatch committed power effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supplementary energy storage is used to compensate for power supply differences, then the committed power can be provided reliably, but the installation, operating, and maintenance costs increase
Solution Approach 1:
The patent combines multiple wind farms into a coordinated dispatch system where the aggregate output compensates for individual variability. By merging the operational control of multiple farms under a unified dispatch management system, the reliability of committed power delivery is improved without requiring supplementary energy storage at each individual farm.
Solution Approach 2:
The dispatch management system performs multiple functions: it monitors operating parameters across all wind farms, predicts power output, coordinates dispatch decisions, and manages reserve power allocation. This multi-functional system replaces the need for dedicated energy storage systems at each wind farm, reducing overall system complexity while maintaining reliability.
2Reliability
If power is purchased from neighboring reserve generators to compensate for insufficient wind power, then the committed power can be provided, but the cost of power generated increases
Solution Approach 1:
The system performs preliminary actions by pre-coordinating dispatch decisions across multiple wind farms based on predicted power output. By proactively managing power distribution and reserve allocation before power shortages occur, the system avoids the need to purchase expensive emergency power from neighboring generators.
Solution Approach 2:
The dispatch management system continuously monitors operating parameters and power output from all wind farms, using this feedback to optimize dispatch decisions in real-time. This feedback mechanism enables the system to efficiently allocate reserve power and minimize the need for costly external power purchases.
3Reliability
If multiple wind farms are coordinated to dispatch power, then the difference between real-time and committed power can be reduced, but the control system complexity increases
Solution Approach 1:
The control system is segmented into hierarchical levels: individual wind farm controllers, regional dispatch management systems, and a central coordinating system. This segmentation allows each level to operate semi-independently, managing local complexity while contributing to the overall coordinated dispatch, thereby reducing the burden on any single control component.
Solution Approach 2:
The dispatch management system acts as an intermediary between individual wind farms and the central coordinating system. It aggregates operating parameters from multiple farms, processes this information, and transmits coordinated dispatch commands, thereby simplifying the control architecture by introducing intermediate management layers that handle local complexity.
