摘要
针对在局部阴影条件下光伏阵列的电气输出特性具有时变不确定性、强非线性和多个局部功率峰值点等特点,综述了目前在国内外研究领域的建模理论依据及模型对应的输出特性研究,并总结分析了各自的优缺点。最后对光伏阵列在局部阴影条件下动态组态模型的研究、提高输出功率多峰值跟踪精度在将来的实现作了探讨。
Time-varying uncertainty, strong nonlinear and a plurality of local power peak point were the electrical output characteristics of the PV array in the condition for partial shadow. Theoretical basis of modeling and characteristics of the corresponding output model was reviewed, and the advantages and disadvantages in the field of domestic and international research were analyzed. Finally, the dynamic configuration model research and enhance tracking accuracy of the output power of more peak point in the condition for partial shadow were discussed.
