摘要
针对盐光互补光伏发电系统的布局优化问题,首先建立了光伏阵列辐照度模型,给出了固定式光伏倾角、阵列间距与发电量的计算方法;随后,以天津某光伏场站为研究对象,利用在设定角度范围内循环寻优,确定了使光伏阵列辐照量最大的最佳倾角;最后,结合阵列间距进行二次循环寻优,求解出使系统发电量最大时的最终倾角,并评估了盐光互补光伏发电系统全生命周期内的发电性能。研究结果表明,所提方法对盐光互补及其他光伏发电系统的布局优化具有实用参考价值。
Aiming at layout optimization in salt-photovoltaic complementary power generation systems,an irradiance model for photovoltaic arrays is firstly established,along with the methods to calculate the tilt angle,spacing and power output for fixed photovoltaic arrays.And then,taking a photovoltaic station in Tianjin as the research subject,a loop optimization approach is employed to determine the optimal tilt angle within a specified range that maximizes irradiance on photovoltaic arrays.Finally,the spacing among photovoltaic arrays is subsequently calculated and used in a secondary loop optimization process to identify the tilt angle that maximizes power output in salt-photovoltaic complementary system,and the power generation performance over full lifecycle of salt-photovoltaic complementary power generation systems is evaluated.The results show that the proposed method can provide a valuable practical guidance for layout optimization in both salt-photovoltaic complementary and other photovoltaic power generation systems.
