【摘要】：太阳能是绿色可再生能源，推广太阳能光伏发电，有利于保护生态环境，促进能源利用与环境保护协调发展。屋顶光伏发电作为我国利用太阳能发电的主要形式，其运作模式、管理机制、政策支持等受到广泛关注。研究屋顶光伏发电系统的运营模式，综合评价不同运营模式下的屋顶光伏发电系统的经济效益，为用户选择提供决策支持，有助于提高用户投资建设光伏发电系统的积极性。本文首先研究了影响光伏发电系统基本效益的主要内容，对屋顶光伏发电系统成本效益进行分析，研究了光伏发电系统成本、发电量及收入的计算方法。其次，分析了屋顶光伏发电系统各利益相关者的利益诉求和不同屋顶光伏系统用户的特点，研究了屋顶光伏发电系统自己建设运营模式和合同能源管理运营模式，结合我国电网公司对光伏并网结算方式的不同，对以上两种运营模式进行细分为：“用户自建，统购统销”、“用户自建，余电上网”、“合同能源管理，统购统销”、“合同能源管理，余电上网”四种运营模式，并提出了不同运营模式下用户净收益的计算方法。然后，以净收益、内部收益率、投资回收期等经济评价指标构成指标体系，以权数非独裁性条件下自主式综合评价方法为支撑，建立屋顶光伏发电系统技术经济评价模型。最后，以实际的屋顶光伏发电系统为例，计算了该系统“用户自建，，统购统销”、“用户自建，余电上网”和“合同能源管理，统购统销”模式下居民用户的各种经济效益指标值，通过分析各指标数据，为用户是否投资建设光伏发电系统提出建议；运用屋顶光伏发电系统技术经济评价模型，对不同运营模式下用户的经济效益进行综合评价，评价结果显示，“合同能源管理、余电上网”运营模式下用户经济效益最好，该模式是用户运营管理屋顶光伏发电系统的最佳选择。
[Abstract]:Solar energy is a green renewable energy. The promotion of solar photovoltaic power generation is conducive to the protection of the ecological environment and promote the coordinated development of energy use and environmental protection. Roof photovoltaic power generation as the main form of solar power generation in China, its operation mode, management mechanism, policy support and so on have received extensive attention. This paper studies the operating mode of rooftop photovoltaic power generation system, synthetically evaluates the economic benefit of roof photovoltaic power generation system under different operating modes, and provides decision support for user selection, which is helpful to improve the enthusiasm of users to invest in the construction of photovoltaic power generation system. In this paper, the main contents that affect the basic benefit of photovoltaic system are studied, and the cost-benefit of photovoltaic system is analyzed, and the calculation method of cost, power generation and income of photovoltaic system is studied. Secondly, it analyzes the interests of stakeholders and the characteristics of different roof photovoltaic system users, and studies the operating mode of the roof photovoltaic system and contract energy management operation mode. Combined with the differences of the photovoltaic grid settlement methods in China's grid companies, the above two operation modes are divided into three categories: "self-building by users, monopoly of purchasing and marketing", "self-building by users, access to the Internet by surplus electricity", "contract energy management, monopoly of purchasing and marketing". Four operating modes of "contract energy management, surplus electricity access" are put forward, and the calculation methods of users' net income under different operation modes are put forward. Then, the index system is composed of net income, internal rate of return, payback period of investment and so on. The techno-economic evaluation model of rooftop photovoltaic power generation system is established based on the independent comprehensive evaluation method under the condition of non-dictatorial weights. Finally, taking the actual photovoltaic power generation system on the roof as an example, the paper calculates that the system is "built by the user, purchased by himself", "built by the user, connected to the Internet" and "managed by contract energy". Based on the analysis of the index values of various economic benefits of the residents under the mode of unified purchase and marketing, the paper puts forward some suggestions on whether the users should invest in the construction of photovoltaic power generation system. Using the technical and economic evaluation model of roof photovoltaic power generation system, the comprehensive evaluation of the economic benefits of users under different operating modes is carried out. The results show that the operating mode of "contract energy management, surplus electricity access" is the best for the economic benefits of users. This model is the best choice for user operation and management of rooftop photovoltaic system.
