Location of Static VAR Compensator (SVC), Thyristor Controlled Series Compensators (TCSC) and other types of Flexible AC Transmission Systems (FACTS) devices is important for the enhancement of practical power systems voltage stability.
In this paper, a Multi-Objective Particle Swarm Optimization (MOPSO) is used to solve a mixed continuous-discrete multi-objective optimization problem in order to find optimal locations of SVC and TCSC. The objectives considered are the increase of security margin against voltage collapse, real power loss reduction and load voltage deviations minimization. Simulations are performed on IEEE 14 test system with FACTS controllers modelled for steady state studies. A contingency analysis to determine the critical outages with respect to voltage security is examined in order to evaluate their effect on the location analysis. The obtained results show that with the allocation of FACTS devices with the proposed approach, the voltage stability is considerably enhanced in both normal state and critical contingencies.
