Analysis Model Of Power Grid Investment Benefits With Clean Substitution Under The New Electricity Reform

With the advancement of the power market reform,The traditional monopoly thinking and market competition demand have become increasingly fierce.The way in which power grid participate in the power market has undergone major changes.At the same time,with the increasingly severe environmental situation,the adjustment of energy structure and the change of energy habits have become an important means of dealing with environmental pollution.Based on above background,the State Grid Corporation proposed a "two substitutions" strategy,namely,implementing clean substitution on the supply side and electric energy replacement on the demand side.Moreover,to promote suply-side structural reforms,clean substitution has become an important development direction in China’s energy application field.Therefore,how grid enterprise adapts to the changes in the new power market,and achieve precise investment and benefit management on the basis of ensuring the stable operation of the power system has become a key concern.Combined the new round of power market reform with clean substitution orientation,The paper,at first,analyses the external policies and internal environment of the grid company’s investment and operation.Secondly,identifies the influencing factors of grid investment benefits under the backgrounds of the new round of power market reform and clean substitution respectively.and then analyzes the cash flow of grid input expenditure under the new situation.Therefore,combined with the actual investment operation process of the power grid,the system dynamics is used to construct the investment capacity and investment planning modules that determine the investment of the power grid,as well as the profit and social responsibility modules that affect the efficiency of the power grid.The above four modules constitute the grid investment benefit model studied in this paper,and then calculate the comprehensive benefits.Finally,using the relevant data to simulate,and the operation results and sensitivity analysis are obtained,and the impact degree on the grid efficiency is analyzed from five aspects of the influencing factors.On this basis,the trend of grid investment benefit management is summarized,and relevant suggestions are put forward.Through the research of the paper,the following results have been obtained,which have certain innovative significance:First,according to the requirements of the new power reform,considering the competition factors,risk factors and policy supervision factors in the power market,the system dynamics model of investment bene fit is constructed,make the power grid achieve risk warning in the changing policy and market environment,grasp the direction of investment management.Second,considering the strategic factors,the concept and model of equity investment income are proposed in the profit module to simulate the investment benefit of energy internet.It is known that the existing investment level has a certain gap from the goal of achieving comprehensive energy income.In order to achieve the income target,it is necessary to expand the equity investment and increase the research and development of technology.The third is that represents the social benefits of the grid in the social responsibility module,by providing social services and contributing to the clean energy consumption,it is concluded that rural power grid construction,power poverty alleviation and new energy consumption are the key areas that need to be focused on improving the social benefits of the grid and thus improving the comprehensive benefits.
