image_compress
本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下：
压缩过程：
1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。
2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。
3. 计算相关矩阵R，其元素定义为 。
4. 计算R的特征值与特征向量，计算每幅子图像与最大特征向量的内积，便得到编码，即压缩后的图像。
(This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.)

IDVR
This paper presents a dual voltage source inverter
(DVSI) scheme to enhance the power quality and reliability of
the microgrid system. The proposed scheme is comprised of two
inverters, which enables the microgrid to exchange power generated
by the distributed energy resources (DERs) and also to
compensate the local unbalanced and nonlinear load. The control
algorithms are developed based on instantaneous symmetrical
component theory (ISCT) to operate DVSI in grid sharing and
grid injecting modes. The proposed scheme has increased reliability,
lower bandwidth requirement of the main inverter, lower
cost due to reduction in filter size, and better utilization of microgrid
power while using reduced dc-link voltage rating for the
main inverter. These features make the DVSI scheme a promising
option for microgrid supplying sensitive loads. The topology and
control algorithm are validated through extensive simulation and
experimental results.
