This paper introduces the application of Particle Swarm Optimization (PSO) to solve the optimal allocation of a STATCOM in a 45 bus system which is part of the Brazilian power network. The criterion used in finding the optimal location is based on the voltage profile of the system, i.e. the voltage deviation at each bus, with respect to its optimum value, is minimized. In order to test the performance of the PSO algorithm in this particular application, different approaches for inertia weight are investigated; also different values of acceleration constants, number of iterations and maximum velocity are considered. A sensitivity analysis with respect to these parameters is carried out to determine the importance of these settings. Results show that the application of PSO is suitable for this type of problem. The STATCOM location is found with less computational effort compared with a exhaustive search and with a low degree of uncertainty.
