This paper investigates the vehicle-to-grid (V2G) potential of the large scale electric vehicle (EV) charging infrastructures where the grid-side interface is based on a Modular Multilevel Converter (MMC). In this topology, each phase of the grid-side interface consists of two arms, each of which...

This paper analyses the requirements for load balancing of a new transformer-less grid interface topology for large-scale electric vehicle (EV) charging infrastructures. The proposed configuration utilizes a Modular Multilevel Converter (MMC) to supply wireless EV chargers from each module. The...

This paper presents a detailed analysis of power transfer efficiency for inductive battery charging systems designed for sub-resonant frequency control during large variations in coupling conditions. It is first demonstrated how the design for power control by sub-resonant operation allows for...

This paper provides an assessment of the effect from virtual inertia provided by an HVDC converter terminal on the Nordic power system. The analysis is based on results from Power-Hardware-in-the-Loop (P-HiL) tests with a laboratory-scale Modular Multilevel Converter (MMC) representing an HVDC...

Recent developments toward selfdriving cars combined with technology for wireless inductive power transfer can enable electric vehicles that are fully autonomous with respect to operation and energy requirements. Furthermore, technology for wireless opportunity charging and dynamic on-road inductive...

Utilization of the modular multilevel converter (MMC) topology can enable transformer-less interfacing between electric vehicle (EV) charging infrastructure and the power distribution grid. Such configurations are claimed to significantly reduce the system costs, space requirements and complexity...

This paper presents an evaluation of two control schemes for virtual inertia support from the converter terminals of an HVDC interconnection. A point-to-point interconnection between asynchronous power systems is assumed, where one terminal controls the dc-side voltage while the other controls the...

...— Second-order Generalized Integrator (SOGI)-based quadrature-signal-generator (QSG) together with either a phaselocked-loop (PLL) or a frequency-locked-loop (FLL) constitute two types of typical synchronization units (i.e., SOGI-PLL and - FLL) that have been widely used in grid-tied converter...

Declining equivalent inertia caused by the massive integration of converter-based technologies can increase the risk of stability problems in the future power system. Control of HVDC systems as Virtual Synchronous Machines (VSMs) for providing emulated inertia is a promising countermeasure against...
