基于区块链的微网群双层能量交易模型
An Two-layer Energy Transaction Model for Microgrid Group Based on Blockchain
摘要
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 con-tinuous 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 con-sensus 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 sys-tems,the transaction framework can effectively improve the data throughput,reduce the data delay,and improve the economic benefits of participants.关键词
