Enhancement of transient stability in fourteen bus system using interline power flow controller

IPFC is a good FACTS controller to reduce imbalance in parallel lines. Transient Instability is a problem faced by the power suppliers in electric power system. Interline Power Flow Controller (IPFC) can be used to solve the problem. This work has proposed multi level IPFC for power quality improvement of multibus system. The objective of this work is to reduce rotor angle derivation during fault using IPFC system. Simulation studies are conducted on nine bus and fourteen-bus systems. The studies indicate improvement in the stability in terms rotor angle derivation. The simulation results indicate that rotor angle deviation with IPFC is much less than that of multibus system without IPFC.
