This paper describes the development of a modular approach for modelling and simulation of coupled energy grids within different kinds of settlement structures. One presented thesis is that the spatial distribution of the demand structure is given by the urban framework and should be the origin of the modelling of coupled energy grids on the distribution level. Thus, the logic is that the grid is developing towards the given and developing demand structure and not vice versa. The defined spatial distribution delivers the loss relevant lengths between the consumers and producers, which are needed for pipes and cables. Following these assumptions, a modular approach was realised by creating a so-called GridConstructor. This constructor allows it to easily build user defined urban frameworks and combine them with a single grid or multiple grids (electricity, gas, heat). These grids can be coupled via different systems. In conclusion, first results of coupled grid simulations are presented.
