Metastudy

The expected effects on the grid, coupled with a high degree of uncertainty regarding the development of e-mobility, are currently motivating a large number of e-mobility research initiatives in recent years. The focus of the investigations and the scenarios considered are very diverse and cover a wide range of aspects. The metastudy is based on 284 national and 36 international studies and research projects. They are the result of extensive research and evaluation of relevant research projects, scientific publications and dissertations. Based on the criteria of completeness of data for quantitative evaluations as well as scope and clarity of conclusions, a pool of 60 studies (52 national and 8 international) was then selected from the field of grid integration of e-mobility. Based on a detailed analysis of the studies, a parameter set was then developed to describe the scenarios. This set of parameters (e.g. market penetration of e-mobility, increase in network load, controllability of charging equipment and its intended use) defines the basis for a uniform evaluation of all selected studies. Since many studies from the pool consider several different scenarios in the sense of this parameter set, 157 evaluable scenarios result. In the quantitative evaluation, the simulation and measurement results from field tests were compared in the studies and in the qualitative part the findings of the studies were summarised by topic.
