On power systems, there are always weakest branches which possibly result in congestion (overload) when capacity distribution among power stations often aims at minimizing generation expenses. To prevent congestion on distribution, it is necessary to adjust generating capacity of some stations, leading to increasing selling prices.
Production cost will be reduced if congestion on rid is effectively solved without changing
the optimal power of these stations. This paper represents the application of identifying
minimum cut (Fmin) to find the congestion position and then pointing out the suitable
positions of Thyristor-Controlled Series Compensator (TCSC). The application will lead
to preventing congestion, increasing the transmission load of the rid, and thus reducing
electrical production cost. Study results on a 7-node network and 14-node IEEE have
proved the effectiveness of the algorithm.
