TY - JOUR A2 - Neves, Francisco A. S. AU - Cen, Zhaohui PY - 2015 DA - 2015/06/16 TI - An Ultrafast Maximum Power Point Setting Scheme for Photovoltaic Arrays Using Model Parameter Identification SP - 424628 VL - 2015 AB - Maximum power point tracking (MPPT) for photovoltaic (PV) arrays is essential to optimize conversion efficiency under variable and nonuniform irradiance conditions. Unfortunately, conventional MPPT algorithms such as perturb and observe (P&O), incremental conductance, and current sweep method need to iterate command current or voltage and frequently operate power converters with associated losses. Under partial overcast conditions, tracking the real MPP in multipeak P-I.或者 P-V.曲线模型变得非常具有挑战性，以及搜索时间和转换器操作的相关增加，导致MPP跟踪过程中丢失了不必要的功率。在本文中，解决了MPPT控制转换器中的注迹缺点。为了将搜索算法与转换器操作分开，展示了模型参数识别方法以估计每个PV面板的缺位条件并构建实时整体 P-I.PV阵列的曲线。随后提出了一种简单但有效的全局MPPT算法，以跟踪整体中的MPP P-I.从识别的PV阵列模型获得的曲线，确保转换器在MPP工作。新型MPPT是超快的，导致跟踪过程中的保守功率。最后，执行不同情景的模拟以验证新颖的方案的有效性和优势。SN - 1110-662X UR - https://doi.org/10.1155/2015/424628 do - 10.1155 / 2015/444628 jf - 国际摄影师Pb - Hindwi Publishing CorporationKW - ER -
