Sector Coupling to Electromobility

The electromobility and energy markets are currently facing a common challenge given that sector coupling is still in the conceptual initial phase. In fact due to the omission of centrally generated control energy with an increasing fluctuating energy originating from solar and wind power, increased energy demand and peak loads, especially due to the ramp-up of electromobility, new distributed control mechanisms must be found to ensure grid stability. However, electromobility not only creates new challenges, with a suitable approach, it also offers the potential to become an integral part of controlling grid stability.

The ramp-up of e-mobility will result in a huge, distributed battery system whose storage capacity can be charged and discharged via the energy interface of bidirectional charging (BDL) in a way that is suitable for the grid. The bundling of the resulting storage capacity creates enormous mobile storage resources and flexibility, which, taking into account the potential of the charging infrastructure and the digital connect interfaces of conventional vehicles, could be used for a range of network-related system services.

Demand-Side Management (DSM) is a framework that addresses these challenges through distributed information sharing, integrated scheduling, and intelligent decision-making across the network. This enables an adjustment of the energy consumption or an optimal use of resources and flexibility, also from electromobility.
 

• Develop novel predictive DSM concepts for electric vehicles which provide optimal time-stamped charging/discharging profiles and charging point connection within a network.
• Real-time emulation of DSM algorithms and ancillary services utilizing a PowerHIL environment with a BDL AC/DC interface as test-under-device.
• Use and extension of the established communication standards of electromobility, including the standards currently available between charging points, electric vehicles mobility operator which will be used in the future with smart charging.
• Experimental validation of ancillary services and bi-directional charging (BDL) in conjunction with the battery management system (BMS) of a test vehicle and a large stack of emulating vehicle batteries.
