异构能源区块链的多能互补安全交易模型

A Model of Multi-energy Complementation and Safety Transaction on Heterogeneous Energy Blockchain

在分布式能源系统的区块链应用中,存在异构区块链间互信困难、并网可扩展性差等不足。针对以上问题,该文提出一种异构能源区块链的多能互补安全交易模型。首先给出异构能源区块链网络的形式化模型,进而引入一种跨链互信交易方法ET-Relay,构造了一种多能互补安全交易模型,通过构建能源索引交易中继链和能源平行链,融合多种能源上链并网,并安全地完成跨链能源协同调度。仿真实验表明,在利用区块链特性确保交易数据安全性的前提下,该模型较好地解决了能源交易系统中分布式能源的多能互补和整合调度的问题。

In the blockchain application of distributed energy system,there are some deficiencies such as difficulty in mutual trust between heterogeneous blockchains and poor grid-connected scalability.In view of above problems,this paper proposes a model of multi-energy complementation and safety transaction on heterogeneous energy blockchain(MCST-HEB).Firstly,a formalized model of heterogeneous energy blockchain network is given,and then a cross-chain mutual trust transaction method of ET-relay(energy trading-relay)is introduced to construct a multi-energy complementation and safety transaction model.This model integrates multiple energy sources into a network and into a blockchain by constructing an energy index transaction relay chain and some parallel chains of energy supply,securely achieving multi-energy complementation and cross-chain collaborative dispatching of distributed grid-connected multi-energy.Simulation results show that,under the premise of using blockchain characteristics to guarentee the security of transaction data,the model can better solve the problem of multi-energy complementary and integrated dispatching of distributed multi-energy grid-connected energy in the energy transaction system equipped with blockchain technology.
