Dynamic DSO network development and planning - integrated decision support in the face of uncertainty

The energy transition of the power, heat and transport systems is taking place in the electrical distribution grids, which poses major challenges for all distribution system operators. Large parts of the infrastructure must be expanded, optimized and digitized quickly and cost-effectively. Classic, mostly manual network planning procedures are reaching their limits with respect to processing times and complexity. Therefore, a central and automated approach was developed that carries out a holistic and multifactorial analysis of all networks. This means that a complete set of needed action is determined, including hotspots due to excessive load flow, age- and condition-related renewal requirements, reliability, and a predefined digitization strategy. Based on the existing and expected need for action, an expansion path emerges that on the one hand provides the right measures at the right time and, on the other hand, compiles and prioritizes them in such a way that as many problems as possible are solved at once or avoided before they would even occur. Time and money are saved and are available for an even faster and more targeted expansion of the networks. In concrete terms, this means more connection capacity in a shorter time at lower costs.
