【摘要】：利用清洁能源替代煤炭等不可再生能源,以保护环境并实现可持续发展是未来能源发展方向。风能作为一种重要的清洁能源,各国都在加大其利用率。我国在供热季节主要是由热电厂供热,由于CHP机组存在热电联耦约束,在“以热定电”模式下,系统调峰能力不足导致风电在供热期送出线路低谷时段上网困难,弃风现象严重。为减少冬季供暖季节弃风率,提升风电利用率和风电场效率,国家大力提倡消纳风电供热。消纳弃风供热能够实现风电就地消纳,若大规模推广能有效降低地区弃风率,现阶段由于风电供热尚未市场化推广。影响消纳风电清洁供热推广的关键是相关利益主体的经济效益,效益直接影响相关企业使用风电供热的积极性。因此对消纳风电供热各利益主体和整个供热系统进行社会经济成本和收入核算具有重要意义。本文对消纳风电供热社会经济总成本计算,对不同利益主体经济成本进行详细分析建模,对环境成本采用LCA方法建立环境评价模型。为系统分析消纳风电供热项目损益情况,本文基于资金时间价值,采用度电成本和单位供热社会经济总成本SE-LCOE来衡量主体的单位总成本,将SE-LCOE与单位供热和发电收入作比较,从而确定损益平衡。本文以某消纳风电供热项目为实际案例,依据社会经济总成本模型,核算了不同主体的成本和收入,并提出热力公司建设储热式电采暖、风电场建立储热式电采暖和热电厂建立储热式电采暖三种可行的投资运行模式,分析了不同模式的损益平衡和热价补偿情况。文章最后从征收环保费用、增加绿色能源补贴和辅助服务机制三方面对消纳风电供热市场化推广提出建议。本文将环境成本引入消纳风电供热系统中,体现清洁能源的环境优势,为消纳风电供热项目热价补偿和损益提供更为科学的依据。
[Abstract]:The use of clean energy instead of non renewable energy, such as coal, to protect the environment and achieve sustainable development is the direction of future energy development. As an important clean energy, all countries are increasing their utilization rate. In the heating season, China is mainly heated by thermal power plants, because the CHP unit has thermoelectric coupling constraints, in the "thermal power setting" Under the model, the lack of peak capacity of the system leads to the difficulty of accessing the wind power in the period of the low valley in the heating period, and the phenomenon of wind abandonment is serious. In order to reduce the rate of discarding wind in the winter heating season, improve the utilization rate of wind power and the efficiency of the wind farm, the state vigorously advocates the elimination of wind power supply. At the present stage, the wind power supply has not been popularized in the market. The key to promoting the promotion of clean heating is the economic benefit of the related stakeholders, and the benefit directly affects the enthusiasm of the related enterprises to use the wind power supply. The economic cost and income accounting are of great significance. In this paper, the total social and economic cost of the wind power supply and electricity supply is calculated, the economic cost of different stakeholders is analyzed and modeled in detail, and the environmental evaluation model is established by LCA method. The total unit cost of the main body is measured by the cost of the degree of electricity and the total social and economic cost of the unit heating, and the balance of the profit and loss is determined by comparing the SE-LCOE with the unit heating and generating income. In this paper, the cost and income of the different subjects are calculated according to the total cost model of the social and economic cost, which is taken as the actual case. This paper puts forward three feasible investment operation modes for the construction of thermal storage type electric heating in Thermotics Inc, the establishment of the wind electric field and the establishment of heat storage type electric heating in the thermal power plant, and the analysis of the profit and loss balance and the heat price compensation in different modes. At the end of the article, three aspects of eliminating the environmental cost, increasing the green color energy subsidy and the auxiliary service mechanism are eliminated. In this paper, the environmental cost is introduced into the wind power supply system to reflect the environmental advantages of clean energy, and to provide a more scientific basis for eliminating the heat price compensation and profit and loss of the wind power heating project.
