Title      Research On Genetic Algorithm Application In Distribution
Network Distribution Network Optimal Planning
Abstract
With the rapid development of the national economy and the improvement of people's living standards, the domestic demand for electricity is increasing day by day. Distribution network is composed of overhead lines, cable, tower, distribution transformer, isolating switch, reactive power compensation capacitors and some ancillary facilities, and it plays an important role in the distribution of power in the power network, so higher security and reliability of the distribution network are required by people. This paper first analyzes the domestic distribution network status and some of the problems, through Matalab software establishing a single power and multi-supply distribution network model with the annual running cost as the objective function, and obtains the optimal line program by the simulation analysis.This paper verifys the accuracy and validity of the genetic algorithm through assessing the convergence of the algorithm.
