The recent and massive investments in Electric Vehicles (EVs) reveal a change of paradigm in the transports sector and the proliferation of EVs will contribute to an effective reduction in the emissions of greenhouse gases. Nevertheless, for the electrical power grids EVs will be extra loads, which will require the demand energy to charge their batteries. With the advent of the Smart Grids, bes...

Due to their flexibility, Electric Vehicles (EVs) constitute an important asset for the integration of renewable energy sources in Smart Grid. In particular, they should have a dual role: as controllable load and mobile generator with low inertia. To perform these tasks, chargers must provide electronics power flow from grid vehicle vice versa. This bidirectionality can also be implemented wire...

Using mobile chargers in wireless rechargeable sensor networks is an option for charging the nodes due to the high cost of power chargers. In order to achieve some performance requirement such as coverage, it is necessary to effectively schedule the mobile chargers to serve every node in the network. We notice that nearly all previous works on mobile charger scheduling assume that the mobile ch...

Fast charging stations are one of the most important section in smart grids with high penetration of electric vehicles. One of the important issues in fast chargers is choosing the proper method for charging. In this paper, by defining an optimization problem with the objective of reducing the charging time, the optimal charging levels are obtained using a multi-stage current method using a gen...

The expected high penetration of battery chargers for electric vehicles (EV) in electric networks is foreseen as a potential problem for power quality. Battery chargers are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, their harmonic emissions must be analyzed and reduced by harmonic mitigation techniques to avoid future problems. This paper analyzes and re...

In vehicle-to-grid (V2G) systems, electric vehicles interact with the grid as distributed energy storage systems that offer many potential benefits. As an energy interface between a vehicle and the grid, the bidirectional converter plays a crucial role in their interaction. Its reliability, safety, cost, efficiency, weight, size, harmonics, and other factors are of essential importance for V2G ...
