Keywords:
Phasor Measurement Units (PMUs), Particle Swarm Optimization (PSO), Tabu-search (TS), hybrid method, Network connectivity.Abstract
This paper presents a methodology to determine the optimal location of phasor measurement units (PMUs) in any network to make it observable. This proposed methodology is based on network connectivity information for the optimal placement of Phasor Measurement Unit (PMU) that minimizes the cost of installation and provide the entire power system observability. The method is based on hybridizing the Particle Swarm Optimization and tabu-search (PSO-TS) algorithm. The tabu-lists are used within the PSO algorithm: the first one aims to differentiate the best solutions obtained by particles while the second prevent local optimal solutions non-respecting the constraints. The proposed algorithm is tested on IEEE 14-bus and IEEE 30-bus systems.
