Optimal placement of PMUs in power systems based on bacterial foraging algorithm

Abstract

This paper aims to optimize the PMU (Phasor Measurement Unit) placement for a full observation of the power network and the minimum number of PMU. Bacterial foraging algorithm (BFA) that is irresistible in high-dimensional function optimization is presented in this paper. The effectiveness and superiority of the proposed algorithm is demonstrated with PMU placement optimization simulation and a redundancy measurement analysis by using IEEE14-bus system and Tehran 41-bus system.
