Optimal Location Methodology for Multiple UPFCs to Reduce Transmission Congestion

Transmission congestion is a major barrier between supplying cheap generation to load centers. Unified Power Flow Controller(UPFC) can help relive transmission congestion. For integrating a UPFC within the optimal power flow, a linear programming based formulation can be used which is easily implementable. Moreover, determining the optimal location of the UPFC is vital for maximizing the ability to manage the line loading of the power system. In this study, a simple and efficient method has been proposed, namely the Discrete Teaching Learning Based Optimization(DTLBO) to find the optimal location of multiple UPFCs for the 39 Bus and 118 Bus System.
