摘要(Abstract)：

为了克服光伏并网逆变系统受外界干扰和系统参数的不确定性等多种因素的干扰,以逆变器的输出滤波电容电压及其导数为状态变量,将反步法和滑模控制相结合,提出了基于反步滑模控制的光伏并网逆变器控制策略。推导了具有参数不确定和外界干扰情况下的逆变器的反馈控制律。为了获取光伏阵列的全局最大功率点(maximum power point,MPP),提出了一种基于改进粒子群优化算法(particle swarm optimization,PSO)的最大功率点跟踪(maximum power point tracking,MPPT)方法,将占空比分为两部分进行初始化,建立了光伏阵列运行功率与占空比之间的线性关系。仿真和试验结果验证了所提控制策略的有效性。
