| Summary: | Power system engineers are continually faced
with the problem of handling large -scale networks arising due to
system expansion and greater interconnections. Large-scale
systems can be solved using piecewise solution technique wherein
the original system is torn into several subsystems, each
subsystem is solved independently and the solutions of
subsystems are tied up to obtain the total solution. In the
proposed method, impedance parameters are consistently used to
solve power flow problem of large power systems. The inverse of
the Jacobian matrix of each subsystem is derived from the bus
impedance matrix of that subsystem. The effect of the cut
elements are accounted through proper power injections. The
proposed power flow method is successfully tested on IEEE
standard systems and found to give good results. |
