| Recent years,wind power in China has developed rapidly,and the annual installed capacity has expanded in a large-scale growth.However,in the process of wind power development,the risks brought to the power grid system by the fluctuation,intermittence and instability of power generation restrict the amount of wind power grid-connected to some extent.The consumption of wind power has become an urgent problem that needs to be solved urgently in the development and utilization of wind power.The development of wind power involves multiple participants in the wind power industry chain,among them,the government is mainly responsible for the establishment of electricity price mechanisms and electricity price policies,and supervises the main participants in the wind power industry,the upstream material providers,component manufacturers and wind turbine manufacturers all serve wind power enterprises,midstream power grid enterprises are responsible for the transmission of wind power,downstream power end users are consumers of electricity.In order to promote the consumption of wind power,participants need to cooperate with each other,so the profit allocation and risk sharing among the main participants of wind power development is very important.Based on the electricity price mechanism,this paper studies the influence of the benchmark electricity price mechanism and quota mechanism on the profit allocation and risk sharing of wind power development.A clear profit allocation scheme can encourage stakeholders in wind power development to play their roles more actively in order to maximize their respective and overall benefits;a reasonable risk sharing proportion can avoid the risk being borne only by a certain stakeholder,and each stakeholder should bear the corresponding risks while gaining the benefits,so as to be beneficial to the long term and stable development of wind power.Based on the wind power electricity price mechanism in China,this paper focuses on the study of profit allocation scheme and risk-sharing ratio among stakeholders in different electricity price mechanisms.Comparing the profit allocation and risk sharing under different electricity price mechanisms to find out the influences of electricity price mechanism on the profit allocation and risk sharing of the core participants in wind power development,as well as the defects and shortcomings of different electricity price mechanisms in the profit allocation and risk sharing.Research in this paper includes following parts:Firstly,starting from the evolution of wind power price mechanisms and electricity price policies in China,the paper focuses on the analysis of the advantages and disadvantages of benchmark electricity price mechanism and quota mechanism in China,makes a comparative analysis of the current wind power price mechanisms with different dimensions,and elaborates the power on-grid electricity quantity guarantee policy、tax incentives and financial subsidies related to wind power electricity price mechanism.It lays a theoretical foundation for the follow-up study of the relationship between the interest subjects under the specific electricity price mechanism.Secondly,starting from the design mechanism of electricity price mechanism,the stakeholders under the two kinds of electricity price mechanisms are determined respectively,analyze the relationships between the stakeholders.Combined with the relevant preferential policies and subsidy policies of wind power,the profit allocate relationship of each stakeholder under different electricity price mechanisms is determined.The cooperative game theory Shapley value method is used to allocate the profits of the benchmark electricity price mechanism and quota mechanism in wind power development,and by selecting relevant data of the wind power industry in 2018,the profits that each stakeholder can allocate in different electricity price mechanisms are obtained.The calculation results show that under the benchmark electricity price mechanism and the quota mechanism,wind power enterprises allocate the most profits,followed by power grid enterprises,and the power users allocate the least benefits.Finally,this paper analyzes the risk factors in the development of wind power under the benchmarking electricity price mechanism and quota mechanism respectively,identifies the main participants of risk sharing in the development of wind power and the situation that each participant shares the risk,and uses the modified TOPSIS evaluation model based on entropy weight method to evaluate the risk sharing under the sub-regional benchmark electricity price mechanism.By using Delphi method to collect the scores of experts on the risk sharing of each participant under the sub-regional benchmark electricity price mechanism,and using entropy weight TOPSIS model to analyze the risk sharing matrix,finally the relative closeness between the comprehensive risk shared and the optimal risk sharing can be got.The results show that under the sub-regional benchmark electricity price mechanism,the risk shared by grid enterprises is the most,followed by wind power enterprises,and finally the power end users;The AHP method is used to evaluate the risk sharing under the quota mechanism,the expert survey method is used to get the judgment matrix and the proportions of each participant sharing various kinds of risks,so the proportion of each participant sharing the comprehensive weight under the quota mechanism is obtained.That is,the grid enterprises share the most risks,followed by the wind power enterprises,and finally the power end users.The result shows that no matter which kind of electricity price mechanism is,power grid enterprises bear the most risk,followed by wind power enterprises,and power users share the least risk.In order to promote the consumption of wind power,improve the utilization rate of wind power,and promote the coordinated development of all stakeholders in the wind power industry chain,this paper studies the benefit-risk distribution relationship between stakeholders under different tariff mechanisms from the perspective of tariff mechanism,,provides ideas for the design of wind power tariff mechanism in China.When designing the wind power electricity price mechanism,we should achieve "benefit sharing,risk sharing",which can promote the long term stable development of wind power effectively and improve wind power consumption in China.Therefore,this paper has certain theoretical value and practical significance. |
