Participation of Electric Mobility in the Ancillary Service Market: A Numerical Assessment of Expected Performance and Revenues

The paper is aimed to provide a numerical assessment of the technical performances and economic results that could be achieved by a fleet of electric vehicles participating in the Ancillary Service Market. To this purpose, the discipline currently in place in Italy for UVAM project, started in 2019, is assumed as a reference: This experimental initiative enabled distributed flexibility resources, such as dispersed generation, controllable loads, storage systems and also e-mobility, to participate in an aggregated form in the Ancillary Service Market. In this framework, the present work investigates the possible exploitation of an electric fleet to supply balance reserve to the power system. For the purpose of the analysis, the results obtained by two different numerical approaches are presented. They are aimed to prove the effectiveness of the e-mobility regulation with respect to its capability to meet the minimum technical requirements that are mandatory for the participation in the project, and the relevant economic sustainability.
