In this paper, the reliable synchronization of oscillatory power networks with different topologies is investigated by presenting two simple control strategies, namely, phase feedback control and frequency feedback control. The power networks are modeled by the coupled second-order Kuramoto oscillators that represent both consumers and generators. Through the simulations on the power networks with control, it is found that both the proposed control strategies can effectively enhance the synchronizability of the power networks, except for the case when the frequency feedback strategy is adopted for a coupled power network with the WS structure. In this case, it is observed that the critical coupling strength reaches the smallest value when the feedback control strength is equal to one and a sudden drop of order parameter occurs as the control strength further increases. This work provides innovative ideas for constructing a cost-effective power system.
