Mobile Emergency Power Supply through the Use of Electric Bus Fleets (V2G) for the Example of the Metropolis of Hamburg

New concepts for the future grid and the energy supply also demand changes in future emergency power supply solutions. It is often not possible to simply replace conventional diesel generators with renewable energy sources. In order to make alternative emergency power supplies viable in the real world, new procedures and structures are needed. A basic distinction is made between stationary and mobile emergency power supplies. Stationary emergency power systems may be found in hospitals, large server farms and other critical infrastructure. The mobile emergency power systems, such as those used by the Technical Relief Agency (THW) or the fire brigade, can be used much more flexibly. One conceptual idea is to use existing electric bus fleet infrastructures as a mobile emergency power supply. This green alternative could replace the conventional diesel generators used today. This paper investigates the use of electric bus fleets as mobile energy storages for emergency power supply usecases. The goal is to examine the general need for buses to be used in a case of emergency power supply, the possible area of coverage depending on the distributed bus depots in Hamburg and the effects on the power requirements of the depots.
