In this work, we derive a model to study and simulate the dynamics of power grids that, after a few approximations, turns out to be the second-order Kuramoto model. We then use this model to perform some numerical simulations that relate to the vulnerability and stability of energy transmission networks. In relation to the stability, assuming the grid is fully functional, and therefore, is in the synchronous state, we analyze how the grid responds to large perturbations, and also, how this response can be influenced by the location of the node being perturbed. We also show how a simple change in the topology or in the transmission capacity of a line can affect the synchronization of the grid. Regarding the vulnerability, some indexes to identify dynamically vulnerable nodes and edges are presented.
