Combined optimal location of FACTS controllers and loadability enhancement in competitive electricity markets using MILP

In this paper, a new methodology for combined optimal location of Thyristor Controlled Phase Angle Regulator (TCPAR) and Thyristor Controlled Series Compensator (TCSC) has been proposed using a mixed integer linear programming approach in the deregulated electricity environment. The methodology is based on DC load flow equations taking constraints on generation, tine flows, TCPAR and TCSC parameters, power angle, and number of FACTS controllers. The system loadability has been determined without and with the combined optimal location of FACTS controllers for a pool model and hybrid model using secure bilateral transaction matrix. The results have been compared for a pool model and hybrid model with and without individual optimal location of FACTS controllers. The proposed technique has been demonstrated on IEEE 24 bus reliability test system.
