基于联盟区块链的电力碳权交易机制设计

Design of carbon emission permit trading mechanism in power industry based on consortium blockchain

碳排放权(以下简称碳权)交易是推动我国实践低碳、节能的市场手段和政策工具。为加强碳权市场的流通、引导市场主体主动响应以及控制温室气体的排放、积极应对国家战略,基于联盟区块链(以下简称联盟链)技术提出了“多对多”的碳权交易应用。通过分析联盟链的技术特征,设计了碳权交易应用的流程和系统架构;设计了碳权交易应用及其机制,并提出了基于联盟链的碳权交易执行逻辑;建立了碳权交易的数学模型,指出了交易的匹配方式;通过算例验证该碳权交易机制和模型的正确性和可行性。由此可以看出,该碳权交易机制相比于传统趸售市场方式有一定的市场效益优势,可以提高参与碳权市场的市场主体的收益,为碳权市场建设提供技术和交易机制的参考。

Carbon emission permit(hereinafter referred to as carbon)trading is a market and policy tool to promote the practice of low-carbon emission and energy conservation in China.In order to stimulate the market circulation of carbon trading,guide market players to respond proactively,control greenhouse gas emissions,and actively respond to national strategies,a"many to many"carbon trading application was proposed based on consortium blockchain technology.Firstly,the application process and architecture of carbon trading system were designed according to the technical characteristics of consortium blockchain.Secondly,the application and mechanism of carbon trading were designed,and the execution logic of carbon trading based on consortium blockchain was proposed.Then,the mathematical model of carbon trading was proposed,and the trading matching method was pointed out.Finally,the carbon trading mechanism and model designed were verified by an example.Through the example,it can be seen that the carbon trading mechanism proposed has advantage in marketing compared with the traditional wholesale marketing,which can improve the interests of market players in the carbon trading and provide a reference for the construction of carbon market.
