USING DYNAMIC CONTROL MODE

A SZEWCZYK April 2018
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.
