【摘要】：基于传统能源短缺及环境保护、节能减排和可持续发展等多方面的需求,可再生能源已经成为我国能源和电力行业发展的新方向。由于太阳能属于可再生能源且光伏发电过程具有清洁和无噪声等优点,光伏发电得到了国内外的大力支持,并获得迅速发展。我国自《可再生能源法》实施以来,针对太阳能发电出台了一系列相关的目标规划、并网政策、上网电价和补贴政策。尤其自2013年以来,国家集中出台了一系列促进分布式光伏发电的具体政策,但由于分布式光伏发电系统成本仍然较高,用户自主投资建设分布式光伏的动力不足,这是制约其大规模发展的重要问题之一。本文基于对不同居民用户用电负荷的分类,结合储能系统,深入分析了我国分布式光伏发电的经济性对每类用户的影响因素,并量化了各种影响因素对用户经济性的影响。同时在研究国内外光伏发电政策的基础上,从经济性的角度,为我国光伏发展提出了建议。本文主要工作如下:1)对不同负荷曲线的居民用户的实际负荷数据进行聚类分析,得到几种不同类型居民用户所对应的典型负荷曲线。基于全寿命周期理论,建立了不可调度式分布式光伏并网发电系统和可调度式分布式光伏并网发电系统两类系统的成本模型,并提出了其经济性评价指标,即净现值(NPV)指标和动态投资回收期指标,并详细提出了其经济性评价流程。2)以天津市的太阳能辐射条件为基础,计算得出单位容量的光伏组件的年功率输出曲线。首先对不可调度式分布式光伏并网发电系统的经济性进行分析,即针对不同类型用户进行各自的净现值分析以及动态回收期影响因素分析,并进行动态回收期灵敏度分析,再对不同类型用户的经济性进行比较。其次,对可调度式分布式光伏并网发电系统进行经济性分析,即净现值分析、动态回收期影响因素以及灵敏度分析。3)分析国外光伏发展较快国家的光伏发电相关政策,总结并分析我国光伏相关的关键政策。考虑我国未来光伏市场发展情况,计算和分析了光伏系统成本和发电量价格补贴两种因素同时变化对不同类型用户的经济性影响。最后,为促进我国分布式光伏的大规模发展提出了建议。
[Abstract]:Based on traditional energy shortage and environmental protection, energy saving and emission reduction and sustainable development, Renewable energy has become a new direction of the development of energy and power industry in China. Because solar energy is a renewable energy and photovoltaic power generation process has the advantages of clean and noiseless, photovoltaic power generation has been greatly supported at home and abroad. Since the implementation of the Renewable Energy Law, China has introduced a series of related target plans, grid connection policies, Internet tariffs and subsidies for solar power generation, especially since 2013. The state has issued a series of specific policies to promote distributed photovoltaic power generation. However, because the cost of distributed photovoltaic power generation system is still high, the power of building distributed photovoltaic system is not enough for users to invest independently in the construction of distributed photovoltaic power. This is one of the important problems restricting its large-scale development. Based on the classification of the power load of different residents and the energy storage system, this paper deeply analyzes the economic impact factors of distributed photovoltaic power generation on each type of users in China. At the same time, on the basis of studying photovoltaic power generation policies at home and abroad, from the perspective of economy, The main work of this paper is as follows: 1) clustering analysis of the actual load data of residents with different load curves. The typical load curves corresponding to several different types of resident users are obtained. In this paper, the cost models of two kinds of systems of non-schedulable distributed photovoltaic grid-connected generation system and schedulable distributed photovoltaic grid-connected generation system are established, and the economic evaluation index, namely net present value (NPV) index and dynamic investment payback period index, are proposed. The economic evaluation flow. 2) is based on the solar radiation conditions in Tianjin. The annual power output curve of the unit capacity photovoltaic module is calculated. Firstly, the economy of the unscheduled distributed photovoltaic grid-connected generation system is analyzed. That is, to analyze the net present value of different types of users and the influencing factors of dynamic payback period, and to analyze the sensitivity of dynamic payback period, and then to compare the economy of different types of users. Secondly, In this paper, the economic analysis of schedulable distributed photovoltaic grid-connected power generation system is carried out, that is, net present value analysis, dynamic recovery period influencing factors and sensitivity analysis. 3) the relative policies of photovoltaic power generation in countries with fast development of foreign photovoltaic power generation are analyzed. This paper summarizes and analyzes the key policies related to photovoltaic in China. Considering the future development of photovoltaic market in China, this paper calculates and analyzes the economic effects of the cost of photovoltaic system and the price subsidy of generating electricity on different types of users simultaneously. In order to promote the large-scale development of distributed photovoltaic in China, some suggestions are put forward.
