In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased. The sizing and placement of DGs in the system must be optimal because a wrong choice has a negative impact on the system behavior. To solve this combinatorial problem, an algorithm known as Firefly algorithm is proposed in this paper. This is a meta-heuristic algorithm inspired by the behavior of fireflies flashing. The main objective of firefly flash is to act as a signaling system to attract other fireflies. Networks tested IEEE69-bus and IEEE33-bus are used to evaluate the effectiveness of this method. The results are compared with those obtained by genetic algorithm (GA) to IEEE69-bus, and Shuffled frog leaping algorithm (SFLA) for IEEE 33-bus.

说明：  matlab小波去噪例程，小波去噪基本实现功能，需要下载matlab自带的Wavelet Toolbox(Wavelet_denoising The basic function of wavelet denoising. It have to download the Wavelet Toolbox that comes with matlab.)

此程序为Gring通用EMD2007之后的版本，其对2003版做了改进，一个程序文件就可以实现EMD的分解(This program for version the Gring General EMD2007 after the 2003 version has been improved, a program file can be achieved EMD decomposition.)

matlab库，用于导入和处理SRTM的DEM的源程序.注意仅支持 SRTM-3文件，不支持 SRTM-1文件(The Matlab SRTM Library is designed to be an easy-to-use interface for importing and manipulating NASA s Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) dataset. )
