| In order to solve the three major challenges of renewable energy generation,grid connection,and consumption,achieve the goal of adhering to green development,improving ecological environment development,and promoting the energy revolution during the 13 th Five Year Plan period,China implemented carbon emission trading(ET)during the 13 th Five Year Plan period,and also implemented the Green Certificate Trading System(TGC)to promote the development and implementation of the Renewable Energy Quota System(RPS).The implementation of carbon emission trading and green certificate trading systems plays a significant role in solving the current major problems of energy shortage and environmental pollution in China,and is also conducive to promoting the consumption of renewable energy and promoting the market-oriented reform of China’s electricity system.Based on the research results of domestic and foreign scholars on ET and TGC,this article studies the impact of ET and TGC on the inter provincial consumption of renewable energy in the electricity market.Firstly,the demand and supply curves of the two were characterized.Based on the volatility and randomness of renewable energy generation,the corresponding reserve settings for conventional energy units were analyzed.The operational reserve demand curve was drawn based on the mechanism model.The analysis of the demand and supply of green certificate carbon emissions rights was derived from the operational reserve demand curve,and the green certificate demand curve and carbon emissions rights supply curve were depicted.Secondly,under the electricity wholesale market and the green certificate market,the spatial Cournot model of two types of power generation companies is constructed,and the objective function of the two types of power generation companies under the multi market is centrally optimized.With the cplex solution,the impact of renewable energy quotas on the medium and long-term market equilibrium of electricity trading is analyzed;Finally,construct a dual level optimization model for renewable energy trading across provinces and regions,taking into account the dual benefits of environment and economy,and construct a profit maximization clearing model.The upper level model considers the carbon trading system and establishes bidding decisions for each power generation company in the transaction;Using MATLAB to solve,analyze the impact of clearing methods on transaction electricity,carbon emissions reduction,and profits of each power generation company,as well as the impact of carbon trading prices on the consumption of clean energy and carbon emission reduction benefits across provinces and regions.The results show that: the electricity market equilibrium model can improve the renewable energy consumption in different regions,and promote the cross-regional adoption of renewable energy;guide the government to set the quota scientifically,and provide ideas for future policy development;the two-level model can promote the renewable energy consumption,and the conventional energy generation companies participate more actively,and realize the reasonable distribution of power generation and benefits,which has a positive effect on the environment and the economy. |
