Wind Power Plant Command Approval via Distributed Ledger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind power plants face challenges in attributing responsibility for operating commands from multiple stakeholders, leading to potential losses and disputes, as the origin of requests is difficult to verify and validate.
Innovation Solution
A distributed system with a blockchain-based approval process ensures that operating commands are validated by multiple pre-approved stakeholders before being implemented, maintaining an indisputable record of approvals across a decentralized network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actors can issue operating commands to the wind power plant, then the plant can respond to diverse operational needs and stakeholder interests, but it becomes difficult to attribute responsibility for specific commands and validate authorization
Solution Approach 1:
The system segments the command validation process into distinct components: command generation by issuing actors, cryptographic signing by each actor's subsystem, distributed storage of signed commands across multiple subsystems, and verification by the wind power plant controller. This segmentation allows multiple actors to participate while maintaining clear attribution of each command to its originating actor through cryptographic signatures.
Solution Approach 2:
The patent introduces cryptographic signatures and a distributed ledger as intermediaries between actors and the wind power plant. These intermediaries provide indisputable evidence of command origin and authorization by cryptographically binding each command to its issuing actor, thereby resolving the responsibility attribution problem while allowing multiple actors to issue commands.
2Productivity
If operating commands are implemented without rigorous approval mechanisms, then the wind power plant can respond quickly to operational needs, but unauthorized or inappropriate commands may cause direct losses or maintenance issues
Solution Approach 1:
The system performs preliminary cryptographic signing and validation of operating commands by multiple subsystems before the wind power plant executes them. This preliminary action ensures that only authorized and validated commands are implemented, preventing unauthorized or inappropriate commands while maintaining a distributed approval process that does not excessively delay execution.
Solution Approach 2:
The distributed ledger provides real-time feedback on the authorization status of each command by recording and broadcasting signed commands from each subsystem. This feedback mechanism allows the wind power plant to verify command authorization before execution, ensuring reliability while maintaining operational responsiveness through automated verification processes.
3Reliability
If a distributed system with multiple subsystems is used to validate commands, then responsibility attribution and authorization validation are improved, but the system complexity increases
Solution Approach 1:
Each subsystem in the distributed system performs multiple functions: generating cryptographic signatures, validating commands, storing records in the distributed ledger, and broadcasting approvals. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining robust authorization validation across multiple subsystems.
4Reliability
If cryptographic validation and distributed ledger storage are implemented, then indisputable evidence of command origin is maintained, but the processing time and computational resources increase
Solution Approach 1:
The patent replaces traditional centralized authentication mechanisms with cryptographic signature verification and distributed ledger technology. This substitution eliminates the need for complex centralized trust verification while providing indisputable evidence of command origin through cryptographic proofs, thereby maintaining reliability while reducing validation time through automated cryptographic verification.
Data Source
AI summary
The invention provides a method for controlling a wind power plant that receive operating command requests via a distributed system comprising a plurality of subsystems each associated with a respective party capable of issuing requests. One subsystem generates a request to operate the wind power plant in accordance with a defined operating command desired by the associated party. The request is broadcast to each of the other subsystems to approve or disapprove the requests. Each subsystem broadcasts to the other subsystems if it approves the request, and each subsystem maintains a database including a record of which subsystems have approved the request. The wind power plant is controlled based on which subsystems have approved the request, where at least one subsystem other than the subsystem that generates the request needs to have approved the request before the plant implements the defined operating command.
