Cost and Benefit Analysis of Distributed Photovoltaic System A Case of Beijing-Tianjin-Hebei Region

Abstract

Abstract-During the 13th five-year plan, China will devote great efforts to promote the development of distributed photovoltaic (PV) industry. It is conducive to energy structure optimization and ecological environment protection in important regions including Beijing-Tianjin-Hebei region, and the development of distributed PV industry depends on the economic feasibility of project investment. The paper analyzes Beijing-Tianjin-Hebei region distributed PV cost and benefit on the basis of SD simulation model and typical projects data. The results show that the development of Beijing-TianjinHebei region distributed PV industry has economic feasibility of long-term investment based on current industry support policies and existing technical level. But subsidies should be more than 0.27 yuan/kWh of Beijing 0.21 yuan/kWh of Tianjin and 0.27 yuan/kWh of Hebei. The paper also shows that in order to reduce the distributed PV operation and investment risk, meanwhile improving the economic feasibility, the main task at present is still carrying out technological innovation.
