Inspection–Repair-Based Availability Optimization of Distribution System Using Bare Bones Particle Swarm Optimization

Abstract

Maintenance is the crucial part for any engineering systems. The performance of engineering systems can be improved by proper maintenance at proper interval of time. Maintenance at proper interval of time is required for the distribution system which is an important subsystem of the power system, to enhance its efficiency and its proper utilization by the customers. In view of the above, in this paper bare bones PSO (BBPSO)-based technique is developed for optimizing inspection- and repair-based availability of distribution systems. The technique is proposed for evaluating the optimum time duration between two inspections of the distribution system with respect to cost function. The result obtained by BBPSO is compared with results of different variants of PSO such as basic particle swarm optimization (PSO), evolutionary particle swarm optimization (EPSO), and adaptive particle swarm optimization (APSO). Radial and meshed distribution systems were used for implementing the above algorithm.
