A novel power system reconfiguration for a distribution system with minimum load balancing index using bacterial foraging optimization algorithm

Abstract

In this paper, the objective of minimum load balancing index (LBI) for the 16-bus distribution system is achieved using bacterial foraging optimization algorithm (BFOA). The feeder reconfiguration problem is formulated as a non-linear optimization problem and the optimal solution is obtained using BFOA. With the proposed reconfiguration method, the radial structure of the distribution system is retained and the burden on the optimization technique is reduced. Test results are presented for the 16-bus sample network, the proposed reconfiguration method has effectively decreased the LBI, and the BFOA technique is efficient in searching for the optimal solution.

Key words： bacterial foraging optimization algorithm (BFOA); distribution system; network reconfiguration; load balancing index (LBI); radial network
