Abstract
This paper presents a flexible strategy using combined differential evolution (DE) and adaptive particle swarm optimization to enhance the system loadability considering all power system security. The proposed strategy has been successfully adapted and applied for solving the multi objective system loadability in coordination with total power loss and total voltage deviation. Two well known FACTS devices, static VAR compensator (SVC) and thyristor controlled compensator (TCSC) are coordinated and installed at optimized location. The proposed algorithm optimizes simultaneously a combined control variables, active power generations, voltage generators, tap transformer, the reactive power controlled by the shunt SVC compensator in coordination with the active power controlled by the series TCSC controller to maximize the system loadability. The proposed approach has been examined and applied to the IEEE 30-Bus. Simulation results compared to the standard PSO and other recent methods confirm the effectiveness of this hybrid variant.
