Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric power systems face challenges in maintaining stable operation due to the variability of renewable energy sources like solar and wind power, which require additional reserve power to balance supply and demand, leading to opportunity losses for power generation facilities when reducing output to secure reserve power.
Innovation Solution
A power generation facility operation device and method that calculates power generation opportunity loss values and reserve power incentive values to determine an optimal reserve power plan, allowing electric power producers to maximize incentives while minimizing opportunity losses by adjusting output accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If renewable energy power sources (solar, wind) are introduced to prevent global warming, then carbon dioxide emissions are reduced, but power generation output becomes unstable due to weather conditions
Solution Approach 1:
The patent implements dynamic output control of renewable energy power sources based on real-time weather conditions and grid requirements. The control device adjusts power generation output dynamically to match both environmental conditions and system stability requirements, resolving the contradiction between maintaining stable output and adapting to weather variability
Solution Approach 2:
The system employs feedback mechanisms where the control device receives information about actual power generation output, grid conditions, and weather forecasts to continuously adjust and optimize power source operation. This closed-loop control ensures stable power supply while maintaining the renewable energy benefit
2Reliability
If output control capability is required to be equivalent to thermal power generation, then connection requirements are met, but operation complexity increases
Solution Approach 1:
The control device is designed to perform multiple functions including output control, reserve power management, and grid code compliance monitoring within a single integrated system. This multi-functional approach meets connection requirements while avoiding the need for separate complex control systems
Solution Approach 2:
The system automatically adjusts power generation output based on pre-set control algorithms and real-time data, reducing the need for manual intervention and complex operational procedures while maintaining compliance with connection requirements
3Reliability
If reserve power is secured by reducing output of power generation facilities, then supply and demand balance is maintained, but power generation opportunity loss increases
Solution Approach 1:
The system dynamically determines reserve power requirements and adjusts power generation output accordingly, rather than maintaining fixed reserve capacity. This dynamic approach minimizes opportunity losses by only reducing output when and where necessary for grid stability
Solution Approach 2:
The control device changes operational parameters such as power generation setpoints and reserve power levels based on real-time grid conditions, weather forecasts, and market signals. This parameter optimization reduces unnecessary output reductions while maintaining supply-demand balance
4Loss of energy
If incentive is given for output variation reduction, then power purchase price increases, but number of windmill groups must be increased to adjust output variation
Solution Approach 1:
The system implements dynamic output adjustment across individual windmill groups based on real-time conditions, allowing the existing fleet to provide output variation reduction services without requiring additional capacity. This dynamic control captures incentive value while maintaining current productivity levels
Solution Approach 2:
The control device optimizes operational parameters such as cut-in speeds, rated speeds, and cut-out speeds of windmill groups to maximize output stability and incentive earnings from existing capacity, avoiding the need to increase the number of windmill groups

AI summary
A power generation facility operation device includes an opportunity loss calculator for calculating a power generation opportunity loss value, (a loss value resulting from losing the power generation opportunity when output of the power generated from a power generation facility is reduced according to a request for provision of reserve power desired by an electric power provider), a reserve power incentive calculator for calculating a reserve power incentive value, (a value equivalent to an incentive obtained by the electric power producer from the electric power provider by output control being performed in the power generation facility and the reserve power being supplied to the electric power provider, and a reserve power plan calculator for calculating a plan of the reserve power that the power generation facility is to secure in order to keep the power generation opportunity loss value below the reserve power incentive value.
