Research on Optimizing Layout and Economy of Distributed Photovoltaic System in Tianjin
With the proposal of the'dual carbon'goal in China,the application potential of distributed photovoltaic system has attracted more and more attention.Taking a case of a distributed photovoltaic system project in Tianjin as an example,this study studies the power generation potential,operation economy and investment payback period of distributed photovoltaic system under different layout methods by combining simulation and calculation.The results show that the optimal layout angle of the photovoltaic system in Tianjin is 40°.When the inclination angle is between 10° and 60°(excluding 40°),the power generation performance drops by about 5%compared to the optimal inclination angle arrangement.When the photovoltaic angle is 10°,the annual photovoltaic power generation of the project is 6 260.7 MWh,the operating cost saving is 2.943 million yuan.When the inclination angle is 40°,the power generation is 2 765 MWh,and the operating cost saving is 1.299 million yuan.The investment payback period for laying with a 10° inclination angle is relatively short,with an investment payback period of 9.47 years.This study provides a case of support for the application and promotion of distributed photovoltaic systems in Tianjin.
