摘要翻译：
光伏发电系统的性能受到环境条件的影响，当部分遮光时，跟踪最大功率点(MPP)并保持最优性能变得更加困难。本文提出了一种改进的最大功率点跟踪(MPPT)方法，利用序贯Monte Carlo(SMC)滤波进行状态估计，并辅以人工神经网络(ANN)对最大功率点进行预测。在增量电导（I-C）MPPT方法的框架下，提出了一种用于MPP序列估计的状态空间模型，该模型基于观测到的电压、电流或辐照度数据预测全局MPP(GMPP)，以改进SMC的估计。此外，本文还采用了一种快速的不平度变化检测方法，使得基于SMC的MPPT方法仅在检测到部分阴影时才借助于人工神经网络的辅助。仿真结果表明，本文提出的增强MPPT方法具有较高的效率，对不同噪声水平下辐照度的快速变化具有较强的鲁棒性。

英文摘要：
  The performance of a photovoltaic system is subject to varying environmental conditions, and it becomes more challenging to track the maximum power point (MPP) and maintain the optimal performance when partial shading occurs. In this paper, we propose an enhanced maximum power point tracking (MPPT) method utilizing the state estimation by the sequential Monte Carlo (SMC) filtering which is assisted by the prediction of MPP via an artificial neural network (ANN). A state-space model for the sequential estimation of MPP is proposed in the framework of incremental conductance (I-C) MPPT approach, and the ANN model based on the observed voltage and current or irradiance data predicts the global MPP (GMPP) to refine the estimation by SMC. Moreover, a quick irrandiance change detection method is applied, such that the SMC-based MPPT method resorts to the assistance from ANN only when partial shading is detected. Simulation results show that the proposed enhanced MPPT method achieves high efficiency and is robust to rapid irradiance change under different noise levels.
