Co-Simulation of Power- and Communication-Networks for Low Voltage Smart Grid Control

The present passive operation in the electricity network is able to handle only limited amount of distributed generation. To avoid extension of grid capacity an intelligent infrastructure and smart grid control is proposed which will guarantee the compliance of limits given by EN50160. For this reason, the different components of the grid have to communicate with the grid controlling unit to transfer real-time voltage measurements and commands. To assess the mutual influences between the electrical power grid on the one hand and the communication system on the other hand, a cosimulation architecture was developed. The methodology in which the components of communication and power simulation are coupled along with some first emulation results are presented in this paper.
