In recent years,due to the continuous development of the power market,the reform has also achieved preliminary results,and the degree of openness of both power generation and sales has continued to increase.However,due to the different backgrounds and characteristics of the participants in the monthly centralized bidding transaction,some new transaction types such as carbon emission rights trading and green certificate trading are also impacting the stable development of the monthly centralized bidding transaction.In order to ensure that users can meet electricity demand at a lower cost in monthly bidding transactions,and to optimize the competitive landscape of market players,it is necessary to deeply understand the market transaction rules,and clarify the quotations and quotation strategies for power generators and users to participate in the market.On the other hand,the development of the electricity market is no longer limited to a single transaction form,and the relationship between multiple transaction forms is closer.Therefore,it is necessary to consider different transaction forms and explore the relationship among them.The paper consists of five chapters,taking into account users’ own risk preferences and the uncertainty of new energy,etc.,and studies the trading strategies of power generators and users in the monthly centralized bidding stage,and fully considers the joint trading of carbon emission rights and green certificates.The impact on the main body of users and the main body of generators.(1)This paper considers the importance of annual contracts in the electricity market,and studies the contract electricity decomposition method considering the participation of renewable energy.Firstly,the decomposition of the annual contract of the power generator is expounded,and a monthly power decomposition model of the power generator considering the participation of renewable energy is proposed;then,considering the uncertainty of the newly added power and the price of electricity in the model,the Q-learning algorithm is proposed to analyze the model.The targeted solution ensures the rationality of thermal power generation and the economy of electricity purchases by electricity purchasers.(2)Based on the participation of renewable energy in the monthly decomposition stage,the research on renewable energy and user participation in the monthly auction market is carried out.Firstly,it is considered that there are many ways for renewable energy to participate in the market,and it is studied that renewable energy participates in the monthly auction market in the form of quotation and no quotation;secondly,it considers the factors that users should consider when making quotations when participating in the monthly auction market.Influence factors,and the quotation strategy model is established according to these influence factors.Finally,a numerical example is given to prove the effectiveness of the method.(3)Finally,the paper considers the multi-subject participation of thermal power units,renewable energy units and users,and clarifies the impact of the joint transaction of carbon emission rights and green certificates on the monthly centralized bidding transaction results of each subject.Firstly,the volume and quotations of multiple entities participating in the monthly centralized bidding transaction were considered,and the transaction process was clarified;secondly,the carbon emission rights and green certificate shortages and balances of each entity were calculated based on the results of the monthly centralized auction clearing of each entity,and the The results are transmitted to the joint transaction,and each subject in the joint transaction is simulated to trade for carbon emission rights and green certificates;finally,the interaction model of the joint transaction and the monthly centralized bidding is established,and the interaction strategy of the joint transaction and the monthly centralized bidding transaction is analyzed. |
