Abstract:

In this paper, the authors present a new approach for an efficient and rapid development of a simplified power grid model, based on a cellular approach. The focus of this paper is the development and evaluation of simplified distribution grid models based on a cellular approach.  The approach presented in this paper is one example for the implementation of annual load profiles by a combination of an improved cellular approach and state of the art load flow calculations. In addition to the analysis of the impact of increasing e-mobility on the power grid presented in this paper, this approach can also be used to analyse the integration of RES, heat pumps, storage systems, power to gas units, etc., or with a combination of these technologies. To illustrate the impact of an increasing grid load of future e-mobility, this paper also includes, among others, the modelling of charging curves in combination with the cellular approach under consideration of the user behaviour of EV-drivers. Finally, the results of the reduction of the calculation time that can be achieved by using the simplified grid model and the results of the load flow calculations of the case study are presented.
