Abstract: Based on a comparative analysis of the differences between carbon emissions trading (CET) market and green certificate trading (GPCT) market, and also on the mechanism of the two markets' impact on the electricity wholesale market, this paper builds an energy optimization model of the electricity wholesale market with the concepts of CET and GPCT systems. Numerical simulation results indicate that: The coordination influences of CET and GPCT system have a positive effect on optimizing the power structure and promoting carbon emission reduction in the power industry. With the total carbon emission target, there exists an optimal combination of carbon emission allowance volume and green power certificate proportion that meets the maximization of the gross profit of each power generation company.

Key words: carbon emissions trading, green power certificate trading, electricity wholesale market, carbon emission allowance
