利用Matlab/Siulink搭建的一个光伏电池充放电模型，通过仿真，能较好地体现光伏电池充放电特性(Use Matlab/Siulink to build a photovoltaic cell charge and discharge model, through simulation, to better reflect the charge and discharge characteristics of the photovoltaic cells)

利用小波变化对金融数据进行去噪，保留数据主要趋势，采用通用阈值去噪。(Changes in the financial data using wavelet denoising, retain data key trends, using a common thresholding.)

给定特征函数，求解正交基,利用了SVM分解，快速有效兼容性好(Given the characteristic function, solving orthogonal basis)

The unified power quality conditioner (UPQC) is a custom power device, which mitigates voltage and current-related PQ issues in the power distribution systems. In this paper, a UPQC topology for applications with non-stiff source is proposed.
