局部阴影条件下的光伏阵列建模与特性仿真

摘要

在光伏阵列数学模型的基础上,推导了局部阴影条件下的光伏阵列数学模型,并在Matlab/Simulink软件上进行了3种典型局部阴影条件下的光伏阵列建模与仿真,仿真结果表明在局部阴影条件下光伏阵列的电流出现拐点,输出功率出现多个局部极大值.%This paper deduces the mathematical model of photovoltaic (PV) array under condition of partial shadowing based on model of PV array and uses Matlab/Simulink software to model and simulate PV array under three typical partial shadowing conditions. Simulation results show that current of PV array appears inflection point and the output power of PV array appears some local maximums under the condition of partial shadowing.
