基于多模型状态估计的光伏阵列MPPT技术
Photovoltaic array MPPT technology based on interacting multiple model state estimation
摘要
Abstract
The maximum power point of photovoltaic array had the characteristics of nonlinear, time-varying uncertainty and more local power peaks under the condition of partial shading.The modern state estimation theory was adopted to establish the dynamic model of PV array output power, and the improved interacting multiple model estimation algorithm was adopted to improve the accuracy of tracking power curve, and restrain the noise to track the maximum power point.On this basis, the photovoltaic array MPPT technology based on interacting multiple model state estimation was proposed.The simulation and experiment verified the correctness and validity of the new MPPT control strategy, which can quickly and accurately track the maximum power point regardless of whether the shadow cases.Thus, the efficiency of photovoltaic power generation was improved.关键词
