The increase of complexity in power system applications makes it difficult to investigate research questions within one dedicated specific environment. This paper shows the coupling between continuous simulation of power systems and discrete-event based simulation of communication in combination with automation and control systems. By co-simulation of conventional power system simulation with communication and automation systems, the impact and dependencies of communication on the system can be investigated. A use case of a low voltage network with an on load tap changer and remote voltage control, based on network voltage measurements is presented. Results of the simulation show a different behavior of the system when taking the communication into account. Interdependency of communication and control can be assessed in a co-simulation setup. Control algorithms can be analyzed and designed with respect to communication time constraints.
