The Evaluation Of The Development Mode Of Electric Energy And Haze Control In Beijing

Along with the rapid economic and social development in our country and the huge economic leap forward,the issue of environmental security has become increasingly prominent.Among them,the issue of air pollution has drawn much attention.People are familiar with pollutants,including sulfur dioxide,nitrogen oxides,in recent years,PM2.5 is recognized.Beijing's air pollution is haze,especially the haze issue shocking.The frequent smog in Beijing has raised public awareness of air pollution and environmental protection.To strengthen haze control and governance and improve the air status of Beijing is an important issue facing Beijing at this stage.Related research shows that the increase of air pollutants caused by the increase of social fossil energy consumption is the most important reason for the increase of fog and haze in recent years in our country.As an important sector of fossil fuel combustion,it is imperative for the power industry to step up technological reforms and improve the energy structure.In the context of prevention and control of smog pollution,changing the energy structure,it is of great theoretical and practical significance to carry out the evaluation and policy research on the economic model of power energy development and haze governance.In this paper,the power industry in Beijing as the research object,first of all,from the macro and micro levels of depth analysis,found that Beijing haze and Beijing's power energy development has a strong correlation,and secondly,the establishment of China's energy environment.economic policy The comprehensive evaluation model IPAC-SGM takes the minimum input cost of electric energy as the objective function,uses the environmental objective as the constraint condition,and uses the policy as the scenario to simulate the existing policy unchanged scenario and the general policy scenario respectively.It strengthens the policy-driven scenario of Beijing According to the calculation of model input data,under the three scenarios,the demand for electric energy in Beijing is on the rise,but the quantity of standard coal consumed varies a lot.Under the standard scenario,the consumption of standard coal continues to rise as the demand for electricity increases.However,as the proportion of non-fossil energy power generation gradually increases,the structural indicators of low-carbon power supply and the indicators of carbon productivity in the power industry show an upward trend.Energy use Efficiency improvement,reduction of pollutant emissions,and optimization of power supply structure.However,the trend of change is relatively slow and the environment can not be rapidly improved.Under the general policy-driven scenario,the coal consumption in power industry will be basically flat after 2021,with a certain degree of development in new energy power generation.By 2030,the structural index of low-carbon power supply will reach 9.05%,and the energy consumption index will also gradually decline,Low-carbon power industry development level is higher.The gradual decline of emission targets shows that the Beijing municipal government can exert good effects on intensifying efforts to limit pollutants emitted by coal-fired power plants.However,inadequate incentives for the development of new energy sources have also caused the power generation costs of the power industry to increase and the burden has been aggravated in the long run.Health and stability of energy reform and change.Under the policy-driven scenario,the coal consumption in the power industry peaked around 2018,and after a period of gentle decline,the solar power generation was encouraged by the Beijing municipal government policy and therefore grew rapidly from 0.8%Gradually increased to 3.69%.The proportion of other new energy power generation also gradually increased,with the total proportion exceeding 10%of the total power generation.All economic evaluation indexes are in the best position in the three types of scenarios.It can be seen that the Beijing municipal government has a very significant role in various policies in the power industry to improve energy efficiency and speed up the environmental pollution caused by the progress of clean energy technologies The effect is the opposite.Adjusting the energy structure,accelerating the progress of clean energy technologies and controlling the energy intensity can all control the PM2.5 concentration to varying degrees;improving the energy utilization efficiency.The PM2.5 concentration is exacerbated by the energy rebound effect.However,it is in line with other policy measures When used,the negative impact of the haze treatment on economic growth can be effectively reduced.Based on the results of this assessment,it is suggested that Beijing should not adopt radical policies or haze measures that prohibit the cost of the system from being too high,in order to curb the development of power energy policies in parallel with the reduction of pollutants and haze treatment.And policies such as over-consumption of gas,government subsidies to support clean energy development,emission charging and carbon taxation system technology upgrades,upgrading of industrial institutions and consumers' environmental responsibility,etc.,can achieve the goal of reducing pollution intensity in power generation Related suggestions.Haze management is a continuing task that requires the concerted efforts of governments,communities and businesses.
