Stability index tracing for determining FACTS devices placement locations

Locating the suitable locations in power system for the purpose of Flexible Alternating Current Transmission System (FACTS) devices installation can be realized via wide variety of techniques, and commonly applied by many researchers are sensitivity analysis and optimization approach. On the other hand, there are also various power tracing techniques have been invented by researchers, but their application is only for transmission service pricing. To try a new method for locating the most suitable locations for FACTS devices placement, this paper has invented a new method for ranking the priority of buses, namely Fast Voltage Stability Index Load Tracing (FVSI-LT) via a new hybrid algorithm, Blended Crossover Continuous Ant Colony Optimization (BX-CACO). The method reflects reliable ranking results after comparison with other methods.
