区域电力能源云储能交易区块链技术研究

Research on regional power energy cloud energy storage transaction blockchain technology

针对区域电力能源调度的实际需求,提出了一种基于区块链的区域电力能源云储能交易技术。该技术在区域电力能源交易架构的基础上,设计了去中心化的云储能区块链交易模型,并进一步细化了业务层、中间件及开放许可链的3层技术架构,从而保证了客户端与分布式后台的有效协同。为进一步提高系统运算效率,提出了基于交易信用评估的共识算法优化方案。通过多维指标联合评估实现对区块链节点的评价,并根据定义交易优先权值完成了节点的信用排序。仿真分析结果说明,所提算法相对于现有算法能够降低恶意交易的概率,同时提高了交易系统的处理能力及响应速度。

According to the actual demand of regional power energy dispatching,this paper proposes a regional power energy cloud energy storage trading technology based on blockchain.Based on the regional power energy trading architecture,a decentralized cloud energy storage blockchain trading model is designed,and the three⁃tier technical architecture of business layer,middleware and open license chain is further refined to ensure the effective cooperation between the client and the distributed background.In order to further improve the operation efficiency of the system,this paper proposes a consensus algorithm optimization scheme based on transaction credit evaluation,realizes the evaluation of blockchain nodes through multi⁃dimensional index joint evaluation,and completes the credit ranking of nodes according to the definition of transaction priority weight.The simulation results show that compared with the existing algorithms,the proposed algorithm can reduce the probability of malicious transaction and improve the processing capacity and response speed of the transaction system.
