USING DYNAMIC CONTROL MODE

02


USE CASES : FAST RESPONDING ENERGY TRANSFER SERVICES

E8: fast responding services based on dynamic control mode

• Dynamic adjustment of the BPT considering complex grid situations and secondary actors for grid services.

• Using dynamic control mode, SECC is also responsible for ensuring e-mobility needs

F4: Energy transfer control based on Dynamic control mode

• The SECC controls the amount of active and reactive power to be transferred during the energy transfer loop.

• During the loop the SECC may change the power boundaries and the active and/or reactive power targets based on SA

requirements and mobility needs.

• EVCC will make its best efforts to follow the changes.

• During the loop the EVCC updates its energy requests in relation with mobility needs


BIDIRECTIONAL POWER TRANSFER (BPT) SERVICES

ServiceDiscovery pair messages

• New services for BPT

• same logic as Charging Services (Wifi and PLC separated into two

services)

ServiceDetail pair messages

Parameter set for BPT services:

• 2 control modes : Dynamic and Scheduled

• Connector (legacy EnergyTransfer Type)

• Generator Mode : current source

• BPT Channel

-AC Charging-AC Bidirectional Power Tranfer (BPT)

-AC Bidirectional Power Tranfer (BPT)-Connector = Three phase-Generator mode = Current source-Control Mode = Dynamic

-Selected service = AC BPT-Selected payment = Plug and Charge

-EV physical limitations-EV mobility need (departure time &energy need) -EVSE physical limitations

-DC Charging-DC Bidirectional Power Tranfer-AC Charging-AC Bidirectional Power Tranfer

Concrete example for AC bidirectional power transfer:

Mobility need is ensured by EVSE

No negotiation, no schedule, no charging profile

EVSE sends a single power set point inside the power transfer loop

-EV physical limitations-EV Mobility need

-Power control set points

Services: fast responding grid services (primary reserve, voltage regulations)

➢ a control mode, without negotiation, where a secondary actor system controls the power flow

fulfilling user's mobility needs and its own constraints.


ENERGY LIMITATIONS

• This parameters are instantaneous values that will change over time during the energy transfer loops.

• They are calculated, updated and sent during all the energy transfer loop by the EV.
