摘要/Abstract

摘要：

随着微网分层分级结构逐渐形成,传统集中式电能交易面临效率、安全等挑战,各微网主体难以对交易做出积极响应。针对该问题,文中提出了一种基于区块链的微网群能量交易双层框架。微网内的中心节点收集下层交易市场的供需盈余信息,并发送到上层微网群交易市场进行能量交易。基于智能合约,采用连续双向竞价机制保证节点之间交易的自由度和公平性,并提出改进实用拜占庭容错算法来实现高效可信的共识过程。所提模型有效减少了微网群与主网的交易量,并提高了能源利用效率。8个微网系统的仿真案例证明交易框架可有效提升数据吞吐量并降低数据延迟,提升参与主体的经济效益。

Abstract:

With the gradual formation of the hierarchical structure of the microgrid, the traditional centralized power trading is facing challenges of efficiency and security, and it is difficult for each microgrid subject to respond positively to the transaction. This study proposes a blockchain-based dual-layer framework for energy trading of the microgrid group. The central node in the microgrid collects the supply and demand surplus information of the lower trading market and sends it to the upper microgrid trading market for energy trading. Based on smart contracts, a continuous two-way bidding mechanism is adopted to ensure the degree of freedom and fairness of transactions between nodes. An improved practical Byzantine fault-tolerant algorithm is designed to achieve an efficient and credible consensus process. The proposed model can effectively reduce the transaction volume between the microgrid group and the main network, and improve the energy utilization efficiency. Through the simulation case of eight microgrid systems, the transaction framework can effectively improve the data throughput, reduce the data delay, and improve the economic benefits of participants.

Key words: blockchian, microgrid, electricity market, two-layer transaction, Byzantine algorithms, smart contract
