“…This scenario compares to the Mirai Botnet, which commandeered 600,000 devices in only a few months (Antonakakis et al, 2017). The growth of electric vehicle ownership and the remote control over high-power domestic EV chargers (currently up to 22 kW) (Ashok et al, 2016) and discharge behavior of household batteries in the future would require a far smaller number of malicious remote IoT acquisitions to cause a powerful MadIoT attack.…”

The success and proliferation of smart enabled electricity grids depends on our ability to reason predict and prevent adversarial behavior. This paper details a novel application of design thinking to smart grid cyber security, presenting a scalable framework for defining, ranking and externally validating future smart grid threats and then modeling adversarial behavior. Using an expert panel for external validation, this paper prioritises three salient threats to smart grid security in the near future: 1) malicious entry to a network operator's control room allowing remote shutdown of grid infrastructure, 2) distract and decoy tactics as a means of diverting resources away from the site of an attack, and 3) manipulation of demand attacks using widespread commandeering of household IoT technology. Smart grids represent a salient test deployment for this framework, given the near complete lack of successful existing attacks from which empirical evidence can be leveraged. Our framework for reasoning about potential future threats is scalable from companyspecific to sector-wide threats and enables risk owners to make well-informed decisions and better prepare against future threats.

Abstract-Charging infrastructure for electric vehicles (EV) will be the key factor for ensuring a smooth transition to emobility. This paper focuses on five technologies that will play a fundamental role in this regard: smart charging, vehicle-to-grid (V2G), charging of EVs from photovoltaic panels (PV), contactless charging and on-road charging of EVs. Smart charging of EVs is expected to enable larger penetration of EVs and renewable energy, lower the charging cost and offer better utilization of the grid infrastructure. Bidirectional EV chargers will pave the way for V2G technology where the EV can be used for energy arbitrage and demand-side management. Solar charging of EV will result in sustainable transportation and use of the EV battery as PV storage. On the other hand, stationary contactless charging and on-road inductive charging of EV will remove the necessity for any cables, eliminate range anxiety issues and pave the way for automated driving. The electromagnetic and power converter design for contactless power transfer systems for future highways is reviewed in this paper.

“…There are several advantages of charging EVs from PV: (i) Reduced demand on the grid as the EV charging power is locally generated from PV [2]. (ii) The local use of PV energy partially/entirely averts the negative impact of distributed generation like reverse power flow and overvoltage problems [3, 4]. (iii) Long parking time of EVs facilitates the EV to support the grid via vehicle‐to‐grid (V2G) technology [5, 6].…”

Charging of electric vehicles (EVs) from solar energy provides a sustainable means to power EVs in the future. A comparison of topologies for a three-port converter to charge EVs directly from photovoltaic (PV) panels is presented in this study. The grid-connected EV charger has a nominal rating of 10 kW and is bidirectional, enabling vehicle-to-grid operation. The topologies are optimally designed considering different switching frequencies, silicon carbide devices, magnetic cores and number of interleaved stages. Nine topologies are compared using a comparison framework, and the best topology is chosen based on the number of components, converter efficiency, volume, controllability and current ripple. The analysis shows that the best topology is a three-port converter with a central direct current link with a 3-leg interleaved boost converter (IBC) for the PV, two-level inverter with sinusoidal modulation for the grid and a 4-phase interleaved flyback converter for the EV. The loss models built are experimentally verified using a 3-leg IBC.
