Abstract

We use PVsyst software to simulate and calculate the first year electricity generation of 4 MW distributed photovoltaic power generation project. In order to analyze and select the suitable power plant operation mode, the total generating capacity of photovoltaic power station in 25 years has been estimated by using component attenuation of 25 years. This research reports on the findings shown by PVsyst software that evaluates the economy aspects brought by two kinds of operation modes which are full grid access mode and spontaneous use of residual power grid access mode. The research content has reference value for the construction of roof distributed photovoltaic power station in China.

Highlights

  • This paper mainly uses the engineering design of PVsyst software to carry out simulation and calculation of the whole project, and draws the first year of power generation of the project, and carries out economic analysis on the whole life cycle of the project

  • According to the latest on-grid tariffs set by the state for the photovoltaic industry in 2018, the photovoltaic power station uses its full-line operation mode to operate its Internet benchmark price of 0.75 yuan/kWh

  • The simulation aims to carry out reliable references which help us analyze and select the suitable power plant operation mode
