Optimal Switch Configuration Algorithm for Dynamically Meshed Power Distribution Grids

This paper deals with the concept of optimal meshed power distribution grids to reduce grid expansion measures. In this regard, the development and application of a tool for dynamic meshing purposes, which considers an optimal switch configuration algorithm, is demonstrated. In this context, the objective function of meshing is depicted. Simulations are carried out on an exemplary grid of the medium voltage level with the application of a scenario for the year 2030. The results show a high potential for dynamically meshed grids with a significant reduction of possible line overloads and therefore, of grid expansion measures. The maximum of reduction of the overloaded line length is nearly 59 %. The potential for an application in a real power grid operation is also assessed in this paper. With regard to the application, a concept of an expert system is developed, which can be integrated into a grid control center in the future.
