Application of Metaheuristic Optimization Methods for Reliability Enhancement of Meshed Distribution System based on AHP

Abstract

This paper describes a methodology for enhancing the reliability performance of meshed distribution system.
In this paper, the reliability indices for sample meshed distribution network is optimized. An objective function in terms
of customer and energy based reliability indices and their respective target values is selected. The weightage coefficients
for these indices are determined by a multi criteria decision making method named Analytic Hierarchycal Process
(AHP). These indices are dependent on the failure rates and repair times of the sections present in the distribution
systems. By modifying failure rates and repair times, the cost associated to them modifies. Hence, the optimization of
objective function is achieved by modifying failure rate and repair time of each section of the sample distribution system
considering the budget allocated to achieve the same. The problem has been solved by applying Jaya and Flower
Pollination (FP) optimization algorithms. The algorithms have been implemented on the sample meshed distribution
system.
