基于区块链激励机制的光伏交易机制设计

Photovoltaic Trading Mechanism Design Based on Blockchain-based Incentive Mechanism

在中国的光伏交易市场中,存在着补贴拖欠、用户数量激增、结算困难等问题。区块链技术凭借自身安全、去中心化、难篡改等特点已成为新型分布式记账清算应用模式。国内外学者也纷纷针对区块链技术在能源领域的应用提出了架构设想。文中提出了一种基于区块链激励的光伏交易机制,可以鼓励各用户间自由、灵活、进行单次交易结算。设计了动态交易系统的智能合约、加密机制、共识机制以及交易流程。设计了基于信誉值的交易机制,可以有效遏制各节点的自私行为,鼓励节点在点对点(P2P)网络中积极有效地传输。最后,针对一个21节点的网络拓扑进行仿真。结果表明,在采用信誉值的交易机制下,用户可以获得更加满意的交易。

There are lots of problems in China' s photovoltaic trading market such as the subsidy default,the increasing number of users and the difficulty of settlement.Blockchain technology has become a new type of distributed account book with its features of own security,decentralization and difficult tampering.Domestic and foreign scholars have proposed architectural ideas for the application of blockchain technology in the energy field.This paper proposes a photovoltaic trading mechanism based on blockchain incentives,which provides a trading method that encourages users to be free,flexible,and perform single settlement.The smart contract,encryption mechanism,consensus mechanism and transaction process of the dynamic trading system are designed.The trading mechanism based on reputation value can effectively restrain the selfish behavior of each node and encourage the nodes to transmit actively in the peer-to-peer (P2P) network.Finally,a 21-node network topology is simulated.The results show that,with the trading mechanism based on reputation value,users can obtain more satisfactory transactions.
