Optimized Allocation of Phasor Measurement Units in Transmission Systems Using Particle Swarm Optimization

Abstract

This paper describes a particle swarm optimization-based method of multi-objective optimal phasor measurement unit's allocation in transmission systems. The allocation problem can be modeled in the binary domain and equated in to work with mono objective meta-heuristics without ignoring its multi-objective nature. Although the particle swarm optimization is more suited for continuous domain problems, with some adaptations, it can also perform well in allocation problems using few iterations. The algorithm and problem modeling adaptations, test systems' results and comparison with other algorithms in literature are presented and exhibits promising results for optimal monitor allocation in small and medium sized transmission systems.
