<strong>Paper Title</strong><br> Maximum Loadability Assessment Of Ieee-14 Bus System Using Facts Devices Incorporating Stability Constraints<br> <br> <strong>Abstract</strong><br> Considering constantly growing electricity demands and transactions, existing power networks required to be enhanced in order to increment its loadability such as to accomplish more power transfers with less network expansion cost. Existing power system loading margin can be upgraded by optimal allocation and setting of FACTS devices. This paper suggests a Particle Swarm Optimization (PSO) based algorithm to determine the optimal location and setting of FACTS devices to improve the loading margin as well as voltage stability and small signal stability. The objective function is formulated as maximizing the loadability of the power system with load generation balance as equality constraint as well as voltage stability, generation limit and line limit constraints as inequality constraint. IEEE 14 - Bus standard test system is taken into account to test the potency of the proposed approach using MATLAB/PSAT.
