基于异构能源区块链的综合能源系统交易模型

Transaction model of integrated energy system based on heterogeneous energy blockchain

综合能源系统是对电、气、热、冷能进行统一规划调度的综合系统,顺应了供给侧改革的趋势。目前综合能源系统的用户呈现个体化、分散化的趋势,传统的单向集中式输配电服务模式逐渐不适应这种趋势。基于区块链技术,设计了一种综合能源系统交易模型。采用异构能源区块链的结构模式,利用智能合约建立了基于价格约束的匹配拍卖机制,保障了清洁能源用户的供能优先级,并采用双重认证机制,保障了交易的可靠性。在实验环境下对所设计模型进行分析,仿真结果验证了所提综合能源系统交易模型的有效性和可行性。

The integrated energy system is an integrated system for the unified planning and scheduling of electricity,gas,heat and cold energy,which conforms to the trend of supply side reform. At present,the users in the integrated energy system show the trend of individualization and decentralization,and the traditional one-way centralized transmission and distribution service mode gradually fails to adapt to this trend. Based on blockchain technology,a transaction model of integrated energy system is designed. The model adopts the structure pattern of heterogeneous energy blockchain,and establishes a matching auction mechanism based on price constraint by using smart contract to guarantee the energy supply priority of clean energy users,and adopts a two-factor authentication mechanism to guarantee the reliability of transaction. The designed model is analyzed in the experimental environment, and the simulative results verify the effectiveness and feasibility of the proposed integrated energy system transaction model.
