Abstract

Available transfer capability is the most important factor for the identification of power transfer from gencos to discos. In a deregulated power system, power producer and customer share a common transmission network for wheeling of the electric power. This may cause violation of line flow, voltage and stability limits and thereby undermine the security limit [1]. To improve the available transfer capability of the system FACTS controllers are used. UPFC is the potential FACTS controller which is used to enhance ATC under deregulated environment. The optimal location for connecting FACTS controller and the amount of voltage and angle to be injected needs to be calculated. Here a hybrid technique is proposed to identify the optimal location for connecting UPFC and the amount of voltage and angle to be injected in the system. The neural network is used to identify the optimal location for connecting UPFC in the system and bees algorithm is used to identify the amount of voltage and angle to be injected in the system. The result shows the significant improvement in ATC and reducing total power losses in the system.
