摘　　要：随着社会经济发展对新能源电力需求的日益增加,发展与之相适应多主体、分时段的电能交易模式可促进电力能源结构的优化。在分析能源区块链结构和运行机理的基础上,针对微网P2P电能交易特征设计了一种多链式能源区块链工作模式,可保证整个过程完整、可监督和真实,进而针对该工作模式提出了动态分区算法优化电能交易过程。设置四组算例仿真实验,由实验结果可知,通过设置初始分区数、依据电能交易频率调整分区能够优化微网P2P电能交易过程,并给出区块大小和节点数目对单个区块链传播时间的影响。With the development of social economy,the demand for new energy power is increasing day by day.The development of multi-agent and time-segment power trading mode can promote the structure optimization of power energy.Based on the analysis of energy block chain structure and operation mechanism,a multi-chain energy block chain operation mode was designed for the characteristics of peer to peer(P2P)power transaction in micro grid,which could ensure the integrity,supervision and authenticity of the whole process.Then a dynamic partition algorithm was proposed to optimize the electric energy trading process.Four sets of simulation experiments were set up.The experimental results show that the initial partition number can be set and the partition can be adjusted according to the power trading frequency to optimize the P2P power trading process of microgrid.And the influence of block sizes and node numbers on the propagation time of a single block chain is also given.
