E-mobility to promote grid stability

14.03.2018

In times not only of increasing renewable feed-in but also of expanding e-mobility, maintaining the balance between electricity generation and consumption is becoming more and more challenging. TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), has started another joint research project on possibilities of utilising electric cars for grid control. The partners are energy service provider The Mobility House and car manufacturer Nissan. In addition to technical solutions, the project members strive to develop and evaluate proposals for regulatory guidelines for vehicle-to-grid technologies.

The new project is a complementation to TenneT’s blockchain projects on flexible grid management. Its technical core is the bidirectional potential of car batteries. These store locally produced electricity, that could be fed back into the grid “for redispatch, in other words, to dispel transmission bottlenecks in the grid”, as Lex Hartman, member of TenneT’s executive board, puts it. Mr Hartman adds, that the new project is apt “to supplement the grid expansion and become an important building block for the energy transition”.

In a first phase of the project, Nissan’s electric vehicles will be used as mobile storage systems in TenneT’s German control areas to directly reduce local supply or demand overload. The vehicle-to-grid software developed by The Mobility House allows automated control of the charging and discharging processes. After successful testing and implementation, the bidirectional charging technology could be used throughout Germany.
