Research On The Behavior Of Power Generators Considering Carbon Emission Constraint Under Renewable Energy Policies

The renewable energy policy aims to promote the development of renewable energy,while the increase in the proportion of renewable energy use is conducive to reducing carbon dioxide emissions.The carbon emission reduction policy aims to encourage enterprises to reduce carbon dioxide emissions.The main form of renewable energy is electricity generation.At the same time,the main targets of China's carbon emission reduction policy also include the power generation industry.From the perspective of the mechanism of action,renewable energy policies can increase the proportion of renewable energy power generation,and accordingly,carbon dioxide emissions will be reduced.Carbon emission reduction policies can promote high carbon emission companies to reduce carbon dioxide emissions,and the use of renewable energy to generate electricity is an effective means to reduce carbon emissions.This paper hopes to analyze the behavior of generation companies under the renewable energy policy considering carbon emission reduction constraints by combining renewable energy policies with carbon emission reduction policies,and study the impact of policy independence or policy crossover on the behavior of power generation companies,with a view to renewable energy policies and The formulation and implementation of carbon emission reduction policies provide some reference.At present,the research on renewable energy promotion policies and carbon emission reduction policies are all operating independently: the research on carbon emission reduction mainly focuses on the design of emission reduction policies,policy implications,and carbon trading models.Research on renewable energy policy focuses more on the effect of policy implementation.There are fewer studies on the analysis of generators' behavioral strategies combined with two types of policies.This paper firstly integrates domestic and foreign relevant research literature,combing the domestic and foreign scholars on the mechanism design of renewable energy policies,implementation effects of renewable energy policies and the impact on the electricity market,the interaction of carbon emission reduction policies and renewable energy policies.And research on the impact of carbon emission reduction constraints on decision-making behavior of market players.Then,this paper introduced the development status of renewable energy in our country,the problems faced by development,summed up the main policy measures for the development of renewable energy in China,and focused on the implications of the fixed on-grid tariff policy and quota-based tradable green certification system,mechanism of action,and main features.Through case studies,the lessons learned from the development of renewable energy in developed countries were summarized.Then,it introduces the important theoretical basis for the following analysis,including carbon emission reduction policies-carbon tax and carbon emissions trading,and the similarities and differences between the two policies.As well as related theories of electricity market entities,including market power theory,Cournot model theory and market supervision theory.Subsequently,on this basis,we discussed the behavioral decisions of traditional generators and renewable energy generators under the fixed on-grid tariff policy and the tradable green certification system,taking into account the carbon tax situation and carbon emissions trading conditions.Four equilibrium models were numerically simulated and solved.Finally,the main conclusions are as follows: First,the FIT and TGC policies can effectively improve the development of the renewable energy power generation industry.Implementing carbon tax under the two policies is more conducive to increasing the share of power generation and emission reduction of renewable energy.It is better than the carbon emission rights policy,but under the carbon emissions trading policy,the total power generation level in the market is higher,the overall social welfare level is higher,and the market equilibrium power price is lower.Second,the FIT and TGC policies not only have a major impact on the renewable energy power generation industry,but also have an important impact on the total supply and demand of the electricity market and even on the electricity prices.Therefore,the FIT and TGC policies have an important role in influencing the investment in the renewable energy industry and guiding industrial restructuring within the industry.Thirdly,a reasonable level of fixed subsidies,renewable energy quotas,carbon tax price levels,and carbon emission rights prices will not only help achieve the goal of promoting the development of renewable energy,but also effectively adjust the industrial structure of the power generation industry and reduce carbon dioxide emissions.
