Cover Story: With the evolution of electromobility and heat pumps in urban areas, distribution system operators are facing new challenges in reinforcing the grids. The power demand is developing rapidly, and grid reinforcement is needed. In this contribution, the electromobility and heat pump loads are introduced through the development scenarios in Germany and their power assumptions. Then, a method for load modeling in grid planning is explained. Subsequently, several grid planning approaches are presented while dividing them into conventional and innovative planning strategies. Among the innovative planning strategies are three variants of load management that regulate different load types. By analyzing several medium voltage grids, this contribution deduces a solid basis for distribution system operators in the form of planning guidelines. View this paper
