Application of Sliding Mode Control in PV Disturbance Method Maximum Power Point Tracking

在两级式光伏并网发电系统中,前级Boost变换器实现太阳能发电系统最大功率点跟踪控制。研究了一种基于滑模控制的最大功率点跟踪策略。实验结果证明,该系统具有优良的动态和稳态性能,能够快速、准确地跟踪太阳能电池的最大功率点,使太阳能发电系统以最大功率输出能量。

In the two-stage grid-connected photovoltaic energy generation system, the first-level Boost converter was used for maximum power point tracking control. A SMC strategy was researched to achieve maximum power point tracking. Experimental results show that the system has a good dynamic and steady state performance and can be quickly and accurately track the maximum power point of solar cells, which ensures the maximum power output of the PV energy generation systems.
