Decentralized Transactive Mechanism in Distribution Network Based on Smart Contract
摘要
Abstract
With the deregulation of power industry and increasing penetration of distributed energy resources,both opportunities and challenges arise in distribution networks.Traditionally a distribution network is operated in a centralized way similar to a transmission network.However,this may incur problems such as high transaction costs,inefficiency,lack of transparency,and cyber-security risk.This paper presented a decentralized transactive distribution system operation method.Firstly,a transactive and decentralized mechanism was proposed.When a prosumer's actual generation/load deviates from her day-ahead schedule,she can send a real-time transaction request to neighboring prosumers and ask help to eliminate the deviation.A Vickrey-Clarke-Groves (VCG) auction method was introduced to encourage honest bidding of her neighbors.A security check method was proposed to ensure that power flows are within limits.Then,an operation method of a transactive distribution system,based on Ethereum blockchain that ensures transparency and information symmetry,was proposed.We also designed a smart contract of transactive energy.The simulation result based on Ethereum private blockchain shows that the proposed decentralized transactive method can deliver multilateral bidding of prosumers,minimize the total cost of eliminating deviation,and ensure the economic and secure operation of a distribution network.关键词
