Dynamical analysis of chaos anti-synchronisation in bidirectionally coupled SMIB power system

Controlled operation of electrical power system is challenging, especially when they unveil chaotic behavior under the privation of reactive power and various disturbances. There are exchanges of power among different parts of power systems involved in its operation. Hence, we investigate the effect of bidirectional coupling between two Single Machine Infinite Bus (SMIB) power systems to study its dynamic behavior. The dynamics of these coupled systems is strongly influenced by variation in coupling strength. The uncoupled systems which are initially in chaotic state can be anti synchronised between each other by suitable choice of coupling form and optimum coupling strength. It is observed that stronger coupling can drive chaotic systems back to periodic state.
