The TSOs are in charge to keep the electricity system permanently balanced. For this purpose, they use the balancing services provided by operators of suitable power plants. Due to the changes in the structure of electric power generation, the flexibility of smaller assets is getting higher importance. One type of these assets are electric vehicles that are capable of providing balancing services through bidirectional charging as well as through a stop or delay of the charging process only. For the integration of electric vehicles into balancing services, a prequalification process is necessary. This process should prove the technical suitability of an asset for providing the different types of balancing product and it consists of focal points. The reaction speed as well as a rapid change of consumption of electric vehicles are sufficient to fulfil the requirements. Larger hurdles seem to arise with the connection in order to steer and measure the asset. Currently, various test cases are in progress to evaluate the suitability of electric vehicles for the prequalification and to identify further process improvements. The four German TSOs work together in order to enable efficient and secure integration of different types of assets into the balancing services.
