Abstract: Recent investigations have shown that with stronger periodic load perturbation power system is experiencing complex chaotic oscillations which threaten the secure and stable operation of power system, even induce the interconnected power system collapse. To control these undesirable chaotic oscillations, a passivity-based adaptive control law is presented in this paper, which transforms the power system into an equivalent passive system. It is proved that the equivalent system can be asymptotically stabilized at different equilibrium points without influence of undeterministic parameters. Simulation results show the proposed control law is very effective and robust against both the uncertainty in system parameters and external noise interference. The research of this paper may help to maintain the power system’s security operation.
