整县屋顶分布式光伏发电经济性模型及关键影响因素
Economic Model and Key Influencing Factors of Rooftop Distributed Photovoltaic Power Generation in the Whole County
摘要
Abstract
[Objectives]In the context of the"dual carbon"goal and new energy grid parity,the economic analysis of rooftop distributed photovoltaic in the whole county is carried out,in order to explore the feasibility of the county-wide distributed photovoltaic mode.[Methods]Based on the cost-benefit theory,the cost and benefit components of the whole life cycle of distributed photovoltaic system are analyzed,and the economic model is established.Taking a residential distributed photovoltaic power generation demonstration zone in Suzhou as an example,the economic feasibility analysis is carried out by selecting the net present value,dynamic payback period and internal rate of return.Moreover,the impact of sensitive factors such as government subsidies,installed capacity costs and operation and maintenance rate on its economy is further analyzed.[Results]With or without government subsidies,in the case of low equipment operation and maintenance rate,the income under the owner operation mode is the highest.In the case of high equipment operation and maintenance rate,the cooperative operation mode has the highest benefit.[Conclusions]The rooftop distributed photovoltaic power generation in the whole county should choose a reasonable operation mode under different operation and maintenance rates.Investors can choose the best operation mode according to specific needs,reduce investment risks and improve the comprehensive benefits.The research results can provide a reference for the subsequent investment decision-making of photovoltaic projects in the county.关键词
