Optimal Placement of Unified Power Flow Controller for Minimization of Power Transmission Line Losses
Abstract—This paper proposes the application of genetic
algorithm for the determination of the optimal placement of
unified power flow controller (UPFC) in a power system so as to
minimize the system losses and enhance the voltage profile. The
method can identify the line in which the UPFC can be located.
UPFC is represented as a decoupled synchronous voltage source
model in the conventional Newton-Raphson load flow NRLF
algorithm. The method of interface of the UPFC model with the
NRLF algorithm is based on the fact that the insertion of UPFC
in a transmission line is equivalent to adding a new PQ bus in
the system, and hence the real and reactive power mismatches
corresponding to this bus are computed after appropriately
modifying the line and bus data. The genetic algorithm
proceeds with an initial randomly generated population. The
effectiveness of each of the individuals in the population is
evaluated on the basis of a fitness function defined to reflect the
effect of the real power losses in the system. Preliminary
investigations indicate the effectiveness of this approach in
minimizing the transmission line losses and the enhancement of
the voltage profile.
