Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transaction matching methods are used between power grid and building energy users, then transaction processes can be completed, but the transparency and efficiency of peak-valley load regulation is insufficient
Solution Approach 1:
The patent introduces a blockchain system as an intermediary between the power grid and building energy users. The blockchain records transaction data including harmony degrees, electricity prices, and transaction quantities in a transparent and tamper-proof manner, while smart contracts automatically execute transaction matching, thereby simultaneously improving transparency through immutable recording and efficiency through automated execution.
2Reliability
If building energy users participate in peak-valley regulation, then power grid operation safety is improved, but transaction fairness and transparency may be compromised
Solution Approach 1:
The patent implements a feedback mechanism where the power grid sends harmony degree requirements and price ranges to building energy users, users respond with their willingness to regulate and pricing, and the blockchain records the complete transaction process. This transparent feedback loop ensures that as users participate in peak-valley regulation improving grid safety, the entire process remains visible and verifiable on the blockchain, preventing information loss and ensuring transaction fairness.
3Productivity
If transaction matching is optimized using PSO algorithm, then transaction harmony degree is maximized, but computational complexity increases
Solution Approach 1:
The patent applies the PSO (Particle Swarm Optimization) algorithm to preliminarily calculate optimal transaction harmony degrees, electricity prices, and quantities before actual transactions occur. By pre-computing these optimized parameters based on historical data and current conditions, the system maximizes transaction harmony while the blockchain subsequently verifies and records the results, balancing computational complexity with optimization effectiveness.

AI summary
A transaction harmony degree-based method and system for transaction matching between a power grid and building energy. The method includes: obtaining a transaction harmony degree of a historical transaction cycle; sending, by using a blockchain, the transaction harmony degree to a corresponding building energy user, and sending a maximum compensated electricity price and an expected compensated electricity price in peak-valley regulation to all building energy users; determining, by each building energy user, a transaction-based compensated electricity price in the peak-valley regulation based on the received transaction harmony degree and the received maximum compensated electricity price and expected compensated electricity price in the peak-valley regulation, and feeding back the transaction-based compensated electricity price in the peak-valley regulation to a power grid; and determining, by the power grid, a building energy user that successfully performs transaction matching with the power grid.
