Abstract:

The launch of national green electricity trading provides a sufficient market-based approach for the realization of the environmental value of green electricity under the background of low-carbon transformation in the power system. With the large-scale permeation of various trading entities and the diversification of green electricity demand on the user side, the current green electricity trading mechanism needs further research to improve flexibility and credibility of certification. It is urgent to optimize the mechanism design to meet the requirements of refined transaction involving massive entities and the reasonable value distribution. Thus, a dual-account mechanism for green electricity trading based on the blockchain technology is proposed in this paper. First, the dual-account management mechanism consisting of the trading account and consumption account is set up,where the circulation of green property and the generation of consumption certificates are recorded separately. Combining with the circulation of green properties, the transaction mode of “coordination of certification and electricity” is designed, which aims to achieve effective connection between green electricity trading and green certificate trading. Finally, the rule contract writing, post-verification design of each transaction process, and block storage design of consumption certificate are carried out for green electricity trading from the perspective of blockchain technology. Trading entities are evaluated by using the historical performance rate to reduce the risk of market operation. The case experiment shows that the mechanism can effectively improve the flexibility and credibility of green electricity trading and alleviate the pressure of renewable energy subsidies to a certain extent.
