Mechanism Design And Simulation Model Construction Of Renewable Portfolio Standards System

In recent years,China’s abandonment of wind and light and insufficient subsidies for renewable energy have become the main bottleneck restricting China’s renewable energy generation.In order to solve this problem,China has officially started to implement the reform from FIT(Feed-in-Tariff)to RPSs(Renewable Portfolio Standards)in 2019,which promotes the consumption of renewable energy and eases the subsidy pressure on renewable energy generation by establishing a green certificate trading market mechanism.However,whether the policy can solve the problems faced by China’s current development of renewable energy power generation is still full of uncertainty.Based on this,this thesis mainly carried out the following works.Firstly,through literature review,we analyze the cases of implementing renewable energy policy reforms in different countries.The study found that FIT can effectively promote the rapid growth of renewable energy power installed capacity.At the same time,it has brought huge financial subsidy pressure to the government,which is the primary factor in the implementation of the policy reform from FIT to RPSs in countries around the world.Secondly,taking the RPSs policy as the research object,through the establishment of a quantitative revenue function model to study the feasibility conditions,possible problems encountered in the successful implementation of the policy and predict its implementation effect.The results show that under this policy,the price of green certificate transactions may be too low,which may not effectively alleviate the pressure on renewable energy subsidies.Therefore,setting the green certificate price trading lower limit is an effective means to solve this problem.Thirdly,in order to solve the problems that may be encountered in the implementation of RPSs,the "Incremental Electricity Price" policy was designed and improved on the demand side to assist the implementation of RPSs,and through the establishment of evolutionary game model,the evolution process of grid enterprises and users’ strategy under this policy is analyzed.The results show that the supplementary policy can effectively improve the possibility of successful implementation of the RPSs policy.Fourthly,in order to theoretically explore a variety of RPSs policies suitable for China’s renewable energy power generation development,an RPSs policy is designed on the supply side.Through the establishment of a multi-dimensional non-cooperative game model,the impact of this policy on different types of power generation enterprises is explored.The research results show that this policy can effectively promote the fossil energy power generation in the region to take the initiative to give up a certain amount of power generation space to fulfill the green power generation obligations.In the end,the proportion of renewable energy power will increase,and the problem of renewable energy consumption will be solved.
