This paper proposes new methodology for the placement of FACTS devices in transmission systems to reduce congestion. Congestion management comprises congestion relief and congestion cost. The traditional approach to remedying congestion lies in reinforcing the system with additional transmission capacity. Although still feasible, this approach is becoming more and more complex and it is often challenged by the public [1]. Congestion relief can be handled by using FACTS devices, where transmission capability may be improved. Congestion relief using FACTS devices requires a two step approach: first, the optimal location of these devices in the network and then, the settings of their control parameters. UPFC and IPFC have full dynamic control on the transmission parameters, voltage, line impedance and phase angle. Real Genetic Algorithm (RGA) optimization technique is used to solve this congestion relief problem while analytical hierarchy process (AHP) with fuzzy sets is implemented to evaluate RGA fitness function. The results are obtained for modified IEEE 5 bus Test System.

“…Among all the functions, the regulation of the power flows in the transmission system has usually been the most primary and general function of UPFC in applications. More and more concerns are being attracted regarding the modelling and control of the power flow regulations by UPFC [1][2][3][4][5].…”

The power flows in the unified power flow controller (UPFC) embedded system is mainly regulated by the two variables containing the magnitude and the phase angle of the output series inserted voltage (OSIV) of UPFC. Different value combinations of the two variables can form multiple regulation modes of OSIV, and the regulation principles and efficiencies for power flows are distinct by different regulation modes. This paper dedicates to research the regulation principles of active and reactive power flow gradients (PFG) to multiple characteristic independent variables (CIVs) at several selected critical points (SCP) of the system in different operation conditions. The CIVs contains the magnitude of OSIV, the phase angle of OSIV, and the phase difference of the system. First, multiple power flow regulation modes of OSIV are designed, the mathematical models of the PFG to each CIV at each SCP are established, and the theoretical principles for the PFG to each CIV at each SCP are analyzed and compared. Next, four typical operation conditions of the system and four regulation scenarios are assumed and case studies for the PFG to each CIV at different SCP are carried out. The test results at each SCP are analyzed both in the two-dimensional planes and three-dimensional spaces. The regulation principles and efficiencies of PFG to each CIV at different SCP are compared with each other and summarized, which can offer useful references for practical engineering and applications of UPFC.
