Empirical Research And Modeling Analysis On The Effect Of Renewable Energy Policy

Energy and environmental issues have become major issues of common concern to the international community. Development of renewable energy has become an important measure to realize sustainable development and national energy security. The realization of the goal that Gross domestic product in 2020 will be twice more than the one in 2000 will enable us to bear more heavy pressure on resource, environment and ecology. Chinese energy demand is increasing rapidly in recent years. There has been a contradiction between energy supply and demand. The country attaches great importance to the development of renewable energy. Many domestic and foreign scholars reach a consensus on the importance of the development of renewable energy. Most research put forward relevant countermeasures to existing policy from the aspects of technology and cooperation. The world is going through the stages of development of renewable energy use of different policy instruments. It is of great practical significance to study the effects of these policies on the development of renewable energy.The main research contents of this thesis are as follows:(1) Study the domestic and international renewable energy policy formulation process. Based on an analysis of the domestic and international renewable energy policy, this thesis advanced the problems that exist in the implementation of renewable energy policies. Meanwhile, compare and analyze the difference between domestic and international renewable energy policy. Renewable energy resources are including wind, solar, biomass and geothermal energy. Due to the development degree of geothermal energy is low, so the types of renewable energy in this thesis are including wind, solar and biomass.(2) Analyze the development environment of renewable energy in Yunnan Province. The analysis is mainly from the following aspects:primary energy resources, Yunnan province electric power market and consumption, renewable energy development present situation, summarizes the advantages and disadvantages of the development environment of existing renewable energy in Yunnan province.(3) Study on the effect of integrated resource planning on renewable energy policy. Firstly, put forward the concept of three different market situations named the reference situation, competition and monopoly. Secondly, put the environmental externality costs in the planning model. Establish the optimization model of the integrated resource planning in different market conditions.(4) Study the effect of renewable energy policy for resource planning. Simulate four kinds of typical renewable energy policy. Such as a tax on carbon dioxide emissions, renewable energy quota system (RPS), sulfur dioxide emissions, strengthen the research and development of renewable energy. Finally, use the tool of MatLab to solve the model. Compare and analize the two different results in both competition and monopoly situation which is concluded in the situation with the policy and without the policy.(5) Based on the above results, analize the effect of the current policies on renewable energy development in Yunnan. The analysis study from the following aspects: the influence of power structure, power balance and power regulation reserve of conventional power; management of renewable energy power generation enterprises; impact on the operation of power grid enterprises; influence on power system stability; effects on the demand side etc.(6) This paper develops dominant firm-competitive fringe models that account for market power in the process of renewable protfolio standard (RPS). It shows that market power could have significant impacts on the renewable energy certificate (REC) price and power prices. Through empirical research, this paper gets the effects of market power on REC and power prices with different RPS requirements increase in different dominant firm situation.(7) Study the development prospect of Yunnan renewable energy and positioning. Based on the research of the Yunnan renewable energy development potential, put forward the future development of renewable energy in Yunnan positioning, development ideas and policy recommendations.
