Abstract

Based on the environmental conditions and light resources of ShiDao, this study proposes a simulation model for the power output of a floating photovoltaic multi-body array system. The model scrupulously factors in the influence of tilt and azimuth angle changes of photovoltaic panels due to the effect of wave on solar radiation reception, and also accounts for the additional mismatch losses caused by differences in radiation among modules within the array. A comparative analysis of the monthly electricity production of both fixed and floating photovoltaic systems is conducted, and the variability of the power output from floating photovoltaic arrays is evaluated using an optimized coefficient of variation. This novel simulation approach can enhance the accuracy of power prediction for offshore floating PV power generation, thereby bolstering the resilience of PV power generation against power system disturbances. The results affirm the feasibility of the floating PV plant from the perspectives of power output and power fluctuation.
