This Use Case is listed before in this Chapter, please refer to paragraph 5.3.7.1
Value added service.
Scope & Level
If network congestion management and V2G energy supply signal hypothesis are
satisfied, an advanced solution for dealing with congestion issues would be using
the V2G availability published from the EVSPs in order to simultaneously impact
positively with a dynamic energy disposal on the grid by sharpening the load
peaks in an adaptive way.

Value added service.
Within the MV/LV energy distribution management domain, the peak energy disposal per load area is one of the fundamental design parameters for the substations and grid reinforcements/maintenance.
DSO defines thresholds peaks on each substation. It is within the DSO responsibility to foresee or evaluate from historical analysis the expected peak energy statistics per hour and/or day/month, in order to minimize shortages of energy supplying and fulfilling quality of services rules set by each national regulatory framework.
 The EVSE Op. is connected to the marketplace through its back-end.
 The EVSP is connected to the marketplace through its back-end.
 The DSO is connected to the marketplace through its front-end towards the
grid.
 The EVSP states in its contracts with the customers that the average time of
recharge is sensitive to the network safety issues (peaks management from
the DSO) and eventually to charging points priority issues (coming from the
deployment strategy of the EVSE Operator).
 A smart recharging infrastructure is needed in order to accomplish peak predefinition demands coming from the DSO to the EVSE Op.
 An adequate communication capability should be endorsed in the EV in order
to receive modulation orders from the DSO through the EVSE energy gateway, especially for low power and time consuming recharges (e.g. 3.3 kW).
 The EVSEs are in communication with an EVSE Op. back-end that aggregates data from each EVSEs.
 The EVSEs Op. back-end aggregates data from each EVSEs and is able to
perform communication with the DSO or the marketplace where the dedicated
service is running.
The EVSE is in communication with the DSO (either directly if the DSO is the
EVSE Operator or indirectly if the EVSE Operator is another actor and therefore
the DSO front-end is not owned by the same actor of the EVSE Op. back-end)
and receives periodic updates on peaks disposal.
