Hierarchical large-scale distribution grid simulation across multiple voltage levels using smart meter data

In this paper, a novel time-series-based simulation concept for large-scale distribution grids between different voltage levels utilizing smart meter data is presented. The main benefit of the presented approach is the ability to acquire a quick and comprehensive overview about bottlenecks and constraint violations in grid topologies of different voltage levels across vast geographical districts. In this manner, the grid operators can focus on the most loaded parts of the grid, disregarding the uncritical ones. Finally, the approach enables the straightforward assessment of additional generation and demand integration scenarios by simulating randomly dispersed units on top of base-case simulations.
