【摘要】：大型并网光伏电站已成为我国太阳能利用的重要形式。作为其基本组成单元,光伏阵列在各类气象条件下的I-U特性对研究大型光伏电站的并网运行特性以及光伏电站的控制算法具有重要意义。该文分析带旁路二极管的光伏组件运行状态,在此基础上给出光伏阵列的隐互补问题模型,并提出基于效用函数的光伏阵列I-U特性求解算法。算例仿真结果表明所提模型和算法具有计算精确度高、计算速度快、收敛性好等优点,适合于任意阴影条件下的大型光伏阵列建模仿真分析。
[Abstract]:Large grid-connected photovoltaic power plants have become an important form of solar energy utilization in China. The I-U characteristics of photovoltaic arrays under various meteorological conditions are of great significance for studying the grid-connected operation characteristics of large photovoltaic power stations and the control algorithms for photovoltaic power plants. This paper analyzes the operation status of photovoltaic modules with bypass diodes. State. On this basis, the implicit complementarity problem model of photovoltaic array is proposed, and an I-U characteristic solution algorithm based on utility function is proposed. The simulation results show that the proposed model and algorithm have high accuracy. It is suitable for modeling and simulation of large photovoltaic arrays under arbitrary shadow conditions because of its high speed and good convergence.
