摘要
在三相两级式并网逆变器数学模型的基础上,将模糊PID控制策略引入光伏发电系统的并网控制中。通过数字仿真和物理仿真表明模糊控制与PID控制相结合的模糊PID控制,改善了光伏系统并网控制的动态过程,能够实现光伏系统的平滑并网。
Based on the mathematical model of the three- phase two-stage PV grid inverter, the fuzzy-PID control strategy is applied in the grid control of PV system in this paper. The digital simulation and physical simulation show that the fuzzy- PID control strategy can improve the PV system grid control dynamic process and realize the smooth connection of the PV system with the power grid.
