Optimal Placement of UPFC for Voltage Drop ...

This paper proposes an approach to find the optimal placement of Unified Power Flow Controller (UPFC) based on the sensitivity of voltage drop with respect to increase the network loads. In order to reduce the solution space, we will establish a priority list. UPFC allows concurrent control of active and reactive power flow and voltage amplitude at the UPFC terminals. These specifications give UPFC the ability to improve the efficiency of the power system during various operating situations. For the case studies, IEEE 14 bus test system is selected and a UPFC is placed in the system. Simulation results show that the proposed method is able to detection the optimal placement of UPFC. Also simulation results show that with the installation of UPFC in network, voltage drop due to increasing the load is compensated.
