光伏电池阵列输出功率受光照强度和温度变化的影响,因此最大功率点跟踪(MPPT)技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中,扰动观察(P&O)MPPT算法因易实现被广泛应用,然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗,并且在光照强度或温度发生突变时表现较差的动态响应。在本文中,提出一种改进型变步长扰动观察MPPT 算法,此方法依据工作点动态调整步长变化,与传统固定步长方法比较,本文提出的方法能有效地提高MPPT 速度和转换效率,通过仿真和实验结果分析,

在MATLAB/Simulink环境中搭建了光伏发电系统模型,其采用最大功率点跟踪(MPPT)控制算法,并加入继电保护逻辑控制模块.通过PSASP的用户程序接口,可将该模型以电流源的形式接入电网模型进行暂态稳定计算.同时提出在电流源并网模式下并网光伏发电系统控制其与电网的无功功率交换为0,因此在潮流计算中可将光伏电站设为PQ节点,并设无功功率为0.CEPRI 36节点系统的仿真结果验证了该模型的正确性,并表明所提模型比常规同步电机二阶经典模型对电网故障的反应更为灵敏,但其对于改善全系统的暂态稳定
