approximation
该程序的作用用于产生正交多项式.该压缩包内含有多个M文件,其中Approximation.m文件为主要的函数文件,它会调用其他的函数文件.该函数提供了和Matlab自身提供的函数一样的条用方式.(The role of the program used to generate orthogonal polynomials. The package contains a number of M documents, including documents Approximation.m function as the main document, it will call a function of other documents. The Matlab function provided and provide their own be a function with the same way.)

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. (2014-11-17
