【摘要】：随着能源可持续发展战略的不断深入,提高能源利用率和保护地球环境逐渐成为能源发展的主题,在这一背景下,天然气冷热电联供作为重要的第二代能源技术在全世界范围内受到广泛的关注。本文以天然气冷热电联供的综合效益为研究对象,从天然气冷热电联供系统的财务效益、环境效益和社会效益进行分析和评价,突出天然气冷热电联供系统的综合效益,促进其在我国的发展。首先,从天然气冷热电联供系统的成本收益及特殊性两个方面分析了影响天然气冷热电联供系统投资效益的影响因素,构建天然气冷热电联供系统投资收益的评价指标体系。为促进天然气冷热电联供系统的发展,降低其运行风险,本文对影响该系统经济性的风险因素进行分析,通过调查问卷对各类风险因素进行调查,采用因子分析法对关键的风险因素进行识别,得出电力外送风险、天然气价格风险、上网电价补贴风险为天然气冷热电联供系统的关键风险源。其次,对我国电源市场进行分析比较,从环境保护角度出发,与常规燃煤电站在大气污染物排放方面进行对比分析,并引进美国大气污染物排放收费标准和罚款制度,结合中国国情对天然气冷热电联供系统环保效益进行了评价；通过模型计算出天然气冷热电联供系统环保效益,并对减排产生的环保效益进行分析。然后,为实现天然气冷热电联供系统的综合效益,构建了包含了环境效益、经济效益及社会效益三方面的评价指标体系,并提出基于AHP-灰色三角白化权函数的综合评价模型,以期全面科学地反映天然气冷热电联供的综合效益。最后,以某天然气冷热电联供建设项目的实例对天然气冷热电联供系统的综合效益进行评价,得出天然气冷热电联供项目具有较好的财务效益及优越的综合效益,为天然气冷热电联供系统的发展提供理论支持。
[Abstract]:With the continuous development of energy sustainable development strategy, improving energy efficiency and protecting the earth's environment gradually become the theme of energy development, in this context,As an important second generation energy technology, natural gas cooling and heat supply has been paid more and more attention all over the world.In this paper, the comprehensive benefit of natural gas combined cooling and heat supply system is studied and analyzed and evaluated from the financial benefit, environmental benefit and social benefit of the natural gas combined cooling and heat supply system, and the comprehensive benefit of the natural gas combined cooling and heat supply system is highlighted.Promote its development in our country.Firstly, from the aspects of cost, benefit and particularity of natural gas combined cooling and heat supply system, this paper analyzes the factors that affect the investment benefit of natural gas combined heating and cooling system, and constructs the evaluation index system of the investment return of natural gas combined heating and cooling power supply system.In order to promote the development of natural gas combined cooling and heat supply system and reduce its operational risk, this paper analyzes the risk factors that affect the economy of the system, and surveys all kinds of risk factors by questionnaire.The key risk factors are identified by factor analysis method, and the key risk sources of natural gas supply system are derived from the risk of electric power outputting, natural gas price risk and electricity price subsidy risk.Secondly, it analyzes and compares the power supply market of our country, from the point of view of environmental protection, compares and analyzes the emission of atmospheric pollutants with conventional coal-fired power stations, and introduces the United States system of charging standards and fines for the discharge of atmospheric pollutants.According to the situation of China, this paper evaluates the environmental benefit of natural gas combined cooling and heat supply system, calculates the environmental protection benefit of natural gas combined heating and cooling system through the model, and analyzes the environmental protection benefit from emission reduction.Then, in order to realize the comprehensive benefit of natural gas combined cooling and heat supply system, an evaluation index system including environmental benefit, economic benefit and social benefit is constructed, and a comprehensive evaluation model based on AHP- gray triangular whitening weight function is proposed.In order to reflect the comprehensive benefits of natural gas combined cooling and heat supply comprehensively and scientifically.Finally, the comprehensive benefit of the combined cooling and heat supply system of natural gas is evaluated with the example of a natural gas combined cooling and heat supply project, and it is concluded that the project has better financial benefit and superior comprehensive benefit.It provides theoretical support for the development of natural gas combined cooling and heat supply system.
