Involved Stakeholder for integration of EVs in the Austrian energy systemThe integration of the mentioned agent with the responsibilities of an aggregator could be realizedwith:1. The extension of a current stakeholder such as an advanced retailer with addedresponsibilities like managing the EVs charging/ discharging strategies anddiffusion/development of charging points in certain areas (except public areas). Theadvanced retailer would act with his fleet and the mentioned strategies as an energyconsumer and as a producer/ power provider for different ancillary services,simultaneously. Thus, the charging/discharging strategies of EVs could fulfilldifferent target functions of DSM. Due to a high penetration of EVs, the charging/discharging strategies could take the security of the grid into account (loadmanagement). This can be accomplished by considering of coming needs from theDSOs. Therefore, the cooperation between aggregators and DSOs in conjunctionwith DSM-application and grid security (controlled charging/ discharging strategies)will be needed.2. The establishment of new actors in an enhanced regulatory framework: This wayleads to the integration of a new stakeholder with the defined responsibilities for anadvanced retailer. This way may result in a change of each stakeholder’s frameworkconditions.If charging stations are available and they could be controlled by an aggregator depending onpenetration of EVs, there would be a corresponding and significant load control potential,respectively.20
