| 摘 要： | 在金融时间序列中，一组金融序列可被视为由不同时间段的分段函数拟合连接而成.利用3σ准则确定分段函数的临界点，并根据AIC准则及调整后R2对分段点进行验证，从而分段点把数据分割成两部分.对两序列分别用合适的函数进行拟合，并用ARMA-GARCH模型对残差序列进行修正.由上证综合指数数据的实证分析结果表明：3σ准则能很好地检索出临界点，同时建立的分段函数模型预测效果要优于ARMA与EGARCH模型，以及ARMA-GARCH模型的引入对模型的精确度有所提高.所介绍的方法简单易懂、便于操作、精度高，为金融投资者和学者提供参考价值.

| Abstract: | In view of the large error of the engineering mathematical model of photovoltaic cell, this paper used the physical equivalent circuit model of photovoltaic (PV) model to simulate the CIGS (copper indium gallium selenium) thin film photovoltaic cell array, and the maximum power point tracking was carried out by using Newton method. The grid connected inverter was based on the direct current control strategy, and the simulation platform was built to achieve three phase photovoltaic grid connected simulation. Simulation results and data show the effectiveness of the proposed model for CIGS thin film photovoltaic cell array and the fast and accuracy of Newton interpolation MPPT algorithm, as well as the practical applicability of direct current control strategy. The engineering analysis and design of CIGS thin film photovoltaic power generation system are of high reference value. |
