Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed energy resources operate independently, then each resource can maintain operational autonomy, but the energy utilization rate decreases due to randomness and intermittency
Solution Approach 1:
The patent combines multiple distributed energy resources into a virtual power plant system that operates collectively rather than independently. By merging resources under a unified blockchain-based trading platform, the system achieves better coordination and higher overall energy utilization while maintaining individual resource ownership and operational characteristics.
Solution Approach 2:
The virtual power plant system enables distributed energy resources to serve multiple functions simultaneously - generating electricity, storing energy, participating in electricity trading, and providing demand response. This multi-functionality increases energy utilization rates while preserving operational flexibility of individual resources.
2Productivity
If distributed energy resources are connected to traditional large power system, then overall energy utilization improves, but electricity supply safety and reliability are threatened
Solution Approach 1:
The patent segments the power system into independent virtual power plant entities that can operate autonomously or connect to the traditional grid. This segmentation isolates potential reliability issues to specific virtual power plants while maintaining overall system stability, as each virtual power plant manages its own distributed resources independently.
Solution Approach 2:
The blockchain-based trading platform acts as an intermediary between distributed energy resources and the traditional power system. This intermediary layer enables secure, transparent transactions and coordination without direct integration of volatile distributed resources into the traditional grid, thus maintaining supply safety while improving energy utilization.
3Adaptability or versatility
If flexible control is implemented for distributed energy resources, then virtual power plant operation is enabled, but trading costs increase due to complexity of coordination
Solution Approach 1:
The blockchain-based trading platform enables distributed energy resources to autonomously participate in electricity trading and demand response programs. Each resource independently makes decisions based on market signals and its own operational constraints, eliminating the need for complex centralized coordination while maintaining flexible control capabilities.
Solution Approach 2:
The system uses blockchain technology to dynamically adjust trading parameters such as pricing, transaction timing, and resource allocation based on real-time market conditions. This parameter-based approach simplifies coordination complexity by replacing complex control mechanisms with market-driven parameter adjustments.
4Productivity
If real-time trading optimization is implemented, then energy utilization rate improves, but system complexity and computational requirements increase
Solution Approach 1:
The patent replaces complex centralized optimization algorithms with a blockchain-based distributed trading system. Instead of using heavy computational mechanics to optimize energy utilization, the system uses market mechanisms and smart contracts on the blockchain to automatically coordinate trading decisions, reducing system complexity while maintaining real-time optimization capabilities.
