Distribution network reconfiguration based on ant colony system algorithm

In this paper, a novel algorithm based on ant colony system algorithm (ACSA) is presented which is used for the reconfiguration of distribution network in order to reduce the power energy losses under normal operation conditions. Combined with the features of distribution network, it applies the ant colony algorithm (ACA) to solve the problem of distribution network reconfiguration. The corresponding mathematical models are established and corresponding algorithms are given. An example of network reconfiguration is given which adopts the network reconfiguration mathematical mode of ACSA for power loss reduction. The main drawbacks of the basic ACA are the slow convergence and stagnation behavior, so some new measures to overcome these shortcomings are proposed in this paper.
