Exploitation And Utilization Of Wind Energy Resources And Analysis Of New Utilization Ways

China's rapid economic growth has led to a large amount of energy consumption,so China has become the world's most emission of greenhouse gases and pollutants.In order to deal with the global climate change,China has established the strategy of green development,implemented a series of policies and measures to save energy and reduce emissions,and achieved remarkable results.In the Paris Climate change Agreement,signed in 2016,the Chinese government reiterated its commitment that by2030,China's non-fossil energy share of primary energy will reach about 20 percent.The exploitation and utilization of abundant wind energy resources is an important part of achieving this strategic goal.However,China's nascent wind power industry Facing the embarrassing situation of "abandon wind and limit electricity",Gansu province is the worst disaster area.In this context,based on a large number of basic data and literature research,and combined with the field research in Gansu,the following work has been done: 1)summarize the characteristics of wind energy resources and the current situation of wind power utilization in China;2)based on the on-the-spot investigation data,this paper analyzes the current situation of the utilization of wind energy resources in Gansu Province and the causes of the generation of abandoned wind power limitation,and puts forward the optimized countermeasures for the development dilemma of wind power industry.3)taking the heating monsoon electricity heating project in Gansu Province as an example,this paper makes a comprehensive benefit analysis on the ways to alleviate the problem of abandoned wind and electricity restriction.The following conclusions are obtained in this paper:(1)Wind energy resources have the advantages of clean,pollution-free,renewable,large theoretical reserves,widely distributed in China,and theconstruction of wind farms requires less land and less consumption of wind power resources.Wind energy industry can promote the economic development of resource producing areas;Wind energy resources also have intermittent,low controllability,low energy density,wind power equipment in operation will produce noise pollution disadvantage.(2)By the end of 2018,the cumulative installed capacity of wind power generation in China is 184.26 million kilowatts,ranking first in the world,but the problem of abandoning wind power limit is serious.The key provinces of wind power generation abandoning wind power limit are Gansu,Xinjiang,Inner Mongolia.(3)There are large spatial dislocations between wind power producing areas and dissipation areas,there are many investments in UHV power grid construction,high technical requirements,high cost of large-capacity storage technology,and interest games among regions and departments.The existing energy system is not suitable for the rapid growth of new energy sources.The main reason for the problem of abandoning wind power limit in Gansu Province is to give way to the heating season wind turbine generator set to give way to the co-generation unit of heat and power.(4)Under the policy of electricity price subsidy,the wind power heating project in Linze County has good economic benefits,and the investment in the wind power heating project in Jinta County cannot be recovered during the effective operation period of the equipment.In tariff subsidy policy and taking into account the environment After positive externality,Linze County wind power heating shows stronger economic benefits,Jinta County wind power heating project has investment feasibility.When there is no electricity price subsidy or small subsidy in wind power heating project,the economic benefit is poor,the profitability is weak,and there is no economic feasibility.Under the hypothetical scenario,the use of wind power heating in Linze County and Jinta County instead of the traditional coal-fired heating method in urban areas,urban environment,social comprehensive benefits and coal-fired large boiler economic benefits are basically equal each year.Linze County,Jinta County wind power heating projects in the heating season can absorb 6.5 million kilowatt-hours and 12.03 million kilowatt-hours of wind power;Linze County and Jinta County urban areas using wind power heating,can absorb 98.77 million kilowatt-hours,105.75 million kilowatt-hours of wind power.The wind power heating project is of great significance to alleviate the problem of abandoning wind power limit.Popularizing the wind power heating project on a large scale can alleviate theproblem of abandoning wind power limit to a great extent.Based on the above research,this paper puts forward the optimization countermeasure to the wind power industry predicament,and puts forward the concrete measure to the wind power heating project construction.
