A review of potential barriers to the participation of electric vehicles in German balancing markets

As conventional flexibility providers are gradually being replaced by variable renewable energies and electricity demand keeps rising, additional flexibility will become increasingly valuable for the power system. Meanwhile, new sources of flexibility known as distributed energy resources are starting to emerge. Among them electric vehicles have a promising potential to provide short-term frequency-control services. However their integration into balancing markets faces various barriers. Based on the existing literature, this paper aims at identifying which potential barriers exist in the case of the participation of electric vehicles in German balancing markets.
