Study And Application Of Power Generation Cost Model Based On Environmental And Resource Externality

China's current power structure is still dominated by coal-fired power generation.It's a problem can not be ignored that how to deal with the relationship between fossil energy utilization and environmental or resource issues,and how to solve the dilemma of new energy consumption to achieve the structure adjustment of China energy.On the basis of providing sufficient,stable and high quality electric power for the demand side,the power enterprises not only need to ensure the sustainable development of national economy,but also must pay attention to the effects of environmental pollution and resource consumption on the society after the to reduce environmental pollution in production and promote energy utilization clean and efficient.At present,the social cost that environmental and resource externality brings is not included in the cost of power generation enterprises and the costs of environment and resource depletion are not reflected in the current electricity price system reasonably.This paper studies the full cost in power generation and explains the necessity of environmental and resource externality cost internalization by elaborating the relevant economic theory.By analyzing production cost,the environmental cost of coal mining,transportation and power generation,the depletion cost of coal resource,this paper establishes a complete cost estimation model of power generation,which adds the environmental and resource externality cost to the power generation enterprise cost accounting system,to provide a basis for the full cost accounting of power generation.This paper establishes a balance model between carbon price of thermal power and the subsidy of new energy,to calculate the minimum carbon price that should be paid by thermal power enterprises under the condition that all the total carbon price paid by thermal power enterprises is used for the subsidy of new energy power generation.Through the calculation and comparison of the actual situation in coal-fired power plants,wind power plants and photovoltaic power plants,and then through the analysis the role of China new energy resource's alternative potential,development of power grid,flexibility modification of thermal power,energy storage technology development on the clean energy substitution,we can see that clean energy alternative enjoys great potential development prospects economically and technologically.Finally,this paper puts forward some policy suggestions on how to promote the internalization of environmental and resource costs,improve China's energy structure and promote environmental and resource protection.This paper constructs a complete cost model of electricity generation considering environmental and resource externalities,and creates a balance model between carbon price of thermal power and new energy subsidy,calculating the full cost of three power generation methods,analyzing the feasibility of clean energy substitution from economic and technical perspective.This paper helps readers understand the real cost of electricity generation and the composition of environmental value and resource depletion value in the complete cost of power generation,and provides the basis for the electricity market price reform and government policy.The internalization of enterprise environmental and resource cost has strong practical significance,which is the inevitable trend of environmental protection and resource utilization economically.The full cost model can also be used to account complete cost of other types of power generation,providing the basis for different energy companies to participate in fair market competition,to promote the structure optimization of China's power industry.
