In recent years there has been growing interest in applying Complex Network Theory to energy transmission networks, or power grids. Several studies focused on the interplay between topology and vulnerability, in many cases regarding the nodes' properties as static. In contrast to this, we employ a dynamic alternating-current model of the nodes that allows us to explore the influence of topology on features of the operating state of the grid (which is a synchronous state). The model, called swing equation model, has been widely used in the engineering community to gain qualitative understanding of how a power grid works. We believe that its combination with Complex Network Theory will lead to new insights. In our numerical investigations we place particular emphasis on the relation between topology of the network and stability of the operating state. Therefore first of all we specify a concept of stability we consider suitable to power grids. Questions we then address include: Which topological properties are beneficial to stability? Which are detrimental?
