摘　　要：该文选用石岛海域环境及光资源条件,综合考虑波浪作用下光伏组件倾角和方位角改变对太阳辐射量接收的影响,以及阵列中各模块辐射量差异所导致额外的失配损失,提出一种考虑波浪荷载的漂浮式多体光伏阵列系统电能输出仿真模型,比较固定式与漂浮式光伏系统的月度发电量并通过优化的变异系数评价漂浮式光伏阵列输出功率的波动性。该仿真方法可提高海上漂浮式光伏发电功率预测精度,进而提升光伏发电适应电力系统扰动能力。研究结果从电能输出及功率波动的角度验证了海上漂浮式光伏发电场的可行性。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.
