“…The primary advantage of an EV is that the design is simple and has a low part count. The primary disadvantage is that the driving range of the vehicle is limited to the size of the battery and the time to re-charge the battery can be 15 minutes to 8 hours, depending on how far the vehicle was last driven, the battery type, and charging method Clement et al, 2008Clement et al, , 2009Acha et al, 2010;Maitra et al, 2009).…”

Distributed generation (DG) in smart grid (SG) is being employed as a means of achieving increased reliability for electrical power systems as regarded by consumers. As the most of DG technologies utilise renewable sources, the power electronic interface plays a vital role to match the characteristics of a DG unit with the grid requirements. This paper presents the power electronics capabilities required for DG systems in SG to convert the generated power into useful power that can be directly interconnected with the utility grid and/or that can be used for consumer applications. Because of the enhancement and the different power ranges of power electronics devices, the development of advanced power electronic interface that is scalable to meet different power requirements, with modular design, lower cost, and improved reliability, will improve the overall performance and durability of smart grid distributed power systems.

“…While the possibility exists for fast, 3-phase charging, it is assumed that each EV will be connected to the network via a standard single-phase AC connection. Although the concept of vehicle-to-grid for local system support or otherwise exists [8], [10], [14], bi-directional flow of electricity to and from an EV battery is not considered in this work. For the CCC method, it is assumed that the load control capability of the EV charging units can be utilised by the distribution system operator (DSO), or a third-party controller, from a remote location.…”

Abstract-Controlled charging of electric vehicles offers a potential solution to accommodating large numbers of such vehicles on existing distribution networks without the need for widespread upgrading of network infrastructure. Here, a local control technique is proposed whereby individual electric vehicle charging units attempt to maximise their own charging rate for their vehicle while maintaining local network conditions within acceptable limits. Simulations are performed to demonstrate the benefits of the technique on a test distribution network. The results of the method are also compared to those from a centralised control method whereby EV charging is controlled by a central controller. The paper outlines the advantages and disadvantages of both strategies in terms of capacity utilisation and total energy delivered to charging EVs.

“…Ideal LV network smart-charging strategy solutions will be casespecific, but nevertheless generic studies show that EVs furthest away to substations will create the most losses; thus it is particularly here where DNOs need to enhance their monitoring and control capabilities [11]. Likewise, a coordinated charging approach reduces power losses and improves the load factor of the network -this can be done by aiming to reduce thermal loading of the cables [10] and/or by obeying flexible tariffs that closely reflect the spot prices of energy [12].…”
