This paper presents a new method to solve the network reconfiguration problem in the presence of distributed generation (DG) with an objective of minimizing real power loss and improving voltage profile in distribution system. A meta heuristic Harmony Search Algorithm (HSA) is used to simultaneously reconfigure and identify the optimal locations for installation of DG units in a distribution network. Sensitivity analysis is used to identify optimal locations for installation of DG units. Different scenarios of DG placement and reconfiguration of network are considered to study the performance of the proposed method. The constraints of voltage and branch current carrying capacity are included in the uation of the objective function. The method has been tested on 33-bus and 69-bus radial distribution systems at three different load levels to demonstrate the performance and effectiveness of the proposed method. The results obtained are encouraging.

Matlab code to study the decorrelation and energy packing efficiency of three transform techniques: Karhunen-Loève transform (KLT), discrete-cosine transform (DCT), and Walsh-Hadamard transform (WHT). Using a given vector of signal samples, it transforms the signal vector, quantize the transformed samples, and reconstruct the signal samples from the quantized samples

将Matlab中现成的数学函数编译为动态链接库，供VC调用，可以省去工程应用中要编写各种C++数学算法的烦恼。这几个工程是我总结的几个案例，分别是VC6.0和VS2008下调用Matlab r2010a生成的dll的例子，还包括2个我自己做的矩阵求逆和数值积分的例子。(Will be ready in Matlab mathematical functions compiled to a dynamic link library for VC call, eliminating the need to write a variety of engineering applications in C++ mathematical algorithms trouble. These projects is a summary of a few cases, respectively, under VC6.0 and VS2008 dll call Matlab r2010a generated examples, including two of my own to do matrix inversion and numerical integration example.)
