Sustained integration of distributed renewable energy sources (especially photovoltaic generation in low voltage grids) has driven the need to expand grid capacities in recent years. Solutions to finding an economic justifiable approach for mains operation in an aging grid environment have become indispensable. This paper highlights the design of a probabilistic simulation environment. Furthermore it provides the possibility to rate new grid technologies taking all conceivable grid states into account. Thereby the simulation is based on actual, measured field data instead of standardised profiles. The aim is to create a simulation environment where different grid situations can be simulated allowing DSOs to optimize their grid planning. Especially low voltage grid simulations with few grid participants lacking accuracy, when modelled by standardized profiles, will benefit from this approach.
