Reconfiguration of Distribution Network with Distributed Generation Based on Improved Ant Colony System Algorithm

Abstract:

In recent years, distributed generation has become a hot topic at home and abroad, and researchers have attached great importance to the new methods of reconfiguration in case of failure. This paper proposes to adopt improved Ant Colony System Algorithm for reconfiguration of the distributed power. Power loss and minimum load balance index as objective function, the ACS algorithms capability of avoiding being trapped in local optima can be enhanced. The algorithm can do better in global search and avoid the problem of the premature convergence. When ACS algorithm is applied to the IEEE33 node system, the simulation results show that the method can not only effectively reduce power losses, but also decrease load balancing index , thus improving the quality of power supply.
