Abstract:

In the present paper, the charging of an electric vehicles fleet is scheduled in order to provide power balance regulation to the electric grid. The starting of e-cars charging can be optimized according to predetermined limits set by users, in order to adjust the power exchange profile of the aggregated fleet. The main objective is to extend the participation to the Ancillary Service Market to new entities, allowing for the harvesting of flexibility also from the e-mobility as support to the power system. The approach proposed is compliant with the recent evolutions in the Italian regulatory framework, and it can be considered a key to meet the decarbonization targets set in perspective by EU. The analysis of the Italian ASM allowed for the evaluation of the model’s performance according to the characteristics of the dispatching requests actually delivered on the ASM to ancillary service providers. In this way, the figures provided in the paper can be considered a valuable reference to evaluate the technical and economic viability of the approach. As a matter of fact, it proved to be very effective in limiting the forecasting error affecting the commitments on the DAM and the imbalance error in the ancillary services provision. Finally, another important fact highlighted by the results is the effectiveness of the optimization method in preserving the quality of the e-mobility service, preventing an unwanted and excessive reduction in the vehicles’ state of charge.
