摘要
针对光伏电池工程数学模型误差较大的问题,本文采用基于光伏电池物理等效电路模型对CIGS(铜铟镓硒)薄膜光伏电池阵列进行建模仿真,并采用牛顿插值算法对CIGS薄膜光伏电池阵列进行最大功率点跟踪,并网逆变器部分则采用直接电流控制策略,由此搭建仿真平台实现三相光伏并网仿真。仿真结果和数据表明了CIGS薄膜光伏电池阵列所建立模型的有效性和牛顿插值最大功率点跟踪算法的快速与准确性,以及直接电流控制策略的实用性。对CIGS薄膜光伏发电系统的工程分析和设计具有较高的参考价值。
In view of the large error of the engineering mathematical model of photovoltaic cell, this paper used the phys- ical equivalent circuit model of photovohaic （PV） model to simulate the CIGS （copper indium gallium selenium） thin film photovoltaic cell array, and the maximum power point tracking was carried out by using Newton method. The grid connected inverter was based on the direct current control strategy, and the simulation platform was built to achieve three phase photo- voltaic grid connected simulation. Simulation results and data show the effectiveness of the proposed model for CIGS thin film photovoltaic cell array and the fast and accuracy of Newton interpolation MPPT algorithm, as well as the practical applicability of direct current control strategy. The engineering analysis and design of CIGS thin film photovoltaic power genera- tion system are of high reference value.
