| 中文摘要: |
| 绿证和碳交易机制是现阶段推动电力系统经济低碳运行的有效手段。但现行的绿证制度在鼓励可再生能源并网、缓解财政补贴压力等方面的表现不佳,现行的碳市场对促进减排效果也不明显,且总体呈现“孤立运作”特征。因此,为打破传统绿证和碳市场交易的壁垒,做好市场机制层面的有效衔接,设计了基于区块链的碳权-绿证联合交易市场框架与激励机制。首先,编写智能合约将购/售电及碳权、绿证交易在以太坊平台运行,确保联合市场交易的安全高效自动执行与信息透明；其次,引入碳通证概念,提出了考虑碳通证的DPoS-CT共识算法,激励市场主体对碳减排做出更多贡献；最后,通过算例分析验证了所提机制可有效激励可再生能源交易和限制火电机组的碳排放量,为碳权-绿证联合交易市场建设提供新思路。 |
| 英文摘要: |
| Green certificate trading（GCT）and carbon emission trading（CET）are effective means to promote low-carbon operation of power system economy at present stage. However, current green card system does not perform well in encouraging grid connection of renewable energy and easing pressure of financial subsidies, and current carbon market has no obvious effect on promoting emission reduction, and generally presents the characteristics of“isolated operation”. Therefore, in order to break the barriers between traditional green certificates and carbon market transactions and effectively link up the market mechanism, a block-chain based carbon rights green certificates joint trading market framework and incentive mechanism were designed. Firstly, smart contracts are compiled to run power purchase/sale, carbon rights and green card transactions on the Ethereum platform, ensuring the safe, efficient, automatic execution and information transparency of joint market transactions. Secondly, concept of carbon token is introduced, and DPoS-CT consensus algorithm considering carbontoken is proposed to encourage market players to make more contributions to carbon emission reduction. Finally, proposed mechanism can effectively stimulate renewable energy trading and limit the carbon emissions of thermal power units through an example analysis, providing new ideas for the construction of the GCT and CET market. |
