Abstract: 
Frequency synchronization of generators is a necessary condition for the operation of power-grid networks. By modeling these generators as a network of coupled phase oscillators, the stability of the desired synchronous state can be analyzed as a function of generator parameters. Non-uniform parameter assignments will be shown to be able to maximize stability significantly beyond what has been previously established for identical parameters. The basin of attraction of the synchronous state at the optimum parameter assignment is global, and it is therefore topmost with respect to both depth and width. The role of heterogeneity in the optimization of network dynamics, as well as computational challenges of systematically identifying optimal parameter choices for any given network will be discussed.
