摘　　要：针对光伏阵列建模存在所需参数较多和计算较繁琐的弊端,基于一种新型的Bezier函数光伏阵列建模方法,利用厂商给定参数对BN20-M进行建模,并与传统迭代法的计算结果进行对比,利用已有的实测数据进行验证,结果表明,Bezier函数计算精度虽略低于迭代法,但具有参数获取方便和计算简单的特点,并能够有效地缩短仿真时间,提高计算效率,证明了Bezier函数在光伏阵列建模中的适用性和有效性。Accordance with the modeling for photovoltaic array required a lot of parameters and tedious calculation, based a new Bezier function modeling method, the given parameters from manufacturers is adopted to model BN20-M, which is compared with traditional iterative method and verify by the existing experimental data. It shows that accuracy of Bezier function slightly lower than that of iterative method, but the parameters required of Bezier model is fewer and the calculation is simplified, so the simulation time is decreased effectively and the calculation efficiency is improved. It is proved the correctness and validity of the proposed Bezier function.
