Munich electrifies - Expansion of Munich's Charging Infrastructure

Skyline Muenchen editedMotivation

Maintaining the purity of the air we breathe is essential for the health and quality of life of all people. Due to the regular exceeding of air pollution limits in German cities and the action filed by the European Commission against Germany as part of the infringement proceedings, a large number of local authorities are faced with the task of reducing NOx emissions promptly and sustainably. In the state capital Munich, the immission limit value for nitrogen dioxide (annual mean limit value of 40 μg/m³) has been significantly exceeded on some of the main roads for years.

The transport sector, in particular diesel traffic, must be named as the main cause of these limit value exceedances, which is why the reduction of traffic-related emissions is expected to have a major effect. In order to realise this initiative, it is possible or even necessary to increase the number of (locally) emission-free vehicles on Munich's roads.

Objectives

The increase in emission-free vehicles is one of the primary objectives of the Sofortprogramm Saubere Luft 2017-2020, in which the FfE is participating as scientific partner within the local project München elektrisiert (Me). This project focuses in particular on the construction and expansion of charging infrastructure in order to make electric mobility more attractive for both private individuals and businesses. Essentially, the positioning, planning, design and concrete technical implementation of charging points as well as the communication of connected vehicles and the implementation of various charging strategies are implemented in Me.

The project is divided into two subprojects:

  • Subproject 1 – Construction of private, commercial and public charging infrastructure in residential, commercial and public car parks
  • Subproject 2 – Construction and operation of charging infrastructure on public land by private providers

In this project, FfE is primarily concerned with the analysis of the network load in the distribution network of the city of Munich. The first project objective of the FfE is to determine and assess the status quo of the grid load in order to identify the resilience and acute need for action in the area of the distribution grids. The next step is to determine the effects of different charging infrastructures and their modes of operation on the distribution networks by means of load flow calculations in order to avoid potential, impermissible network conditions in the mid-term. For this purpose, the simulation model GridSim developed at the FfE will be applied and extended by further types of charging infrastructure. The evaluation of the implications for the energy industry is also the aim of the investigations. In the course of the project, heuristics will be identified from the results and recommendations for action will be derived.

Funding and project partners

The described contents will be processed by the FfE within the joint project München elektrisiert. The FfE-activities in the joint project Me are funded within the context of the Sofortprogramm Saubere Luft 2017-2020 (funding code: 01MZ18010B). This addresses the call for funding "Construction of charging infrastructure for electric vehicles in close connection with the removal of existing network barriers and the development of low-cost infrastructure and mobile metering charging points" issued by the Federal Ministry of Economic Affairs and Energy (BMWi) on 28 December 2017.

Within the joint project Me the FfE will be supported by the Department of Environment and Health of the City of Munich, the Technical University of Munich and the Bundeswehr University Munich. Associated partners are the Chamber of Trade and Crafts for Munich and Upper Bavaria and the Chamber of Industry and Commerce for Munich and Upper Bavaria. Furthermore, the FfE-activities are supported by the Stadtwerke München in their function as a local distribution network operator through the provision of data.
