Abstract We investigate numerically the security enhanced optical communication which can be used in smart grid, while the time-delay signature suppression, intelligent control and high quality communication are reached at the same time. In this paper, the communication system includes the driven part, national dispatching control centre (NDCC) and the controlled substations (CSs). To enhance the security of communication system, the driven part which includes two semiconductor lasers, is employed to suppress the time-delay signature. Also, the chaos synchronization between NDCC and different CSs can be selectively realized by controlling the injection parameters. Finally, the high quality communication between NDCC and CS1 is discussed. This research paves the way to the application of chaotic communication in smart grid.
