Priority-based vehicle-to-grid scheduling for minimization of power grid load variance

During the last few decades, electric vehicles (EVs) have emerged as a promising sustainable alternative to traditional fuel cars. The work presented here is carried out in the context of the Horizon 2020 project MERLON and targets the impact of EVs on electrical grid load profiles, while considering both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) operation modes. Three different charging policies are considered: the uncontrolled charging, which acts as a reference scenario, and two strategies that fall under the umbrella of individual charging policies based on price incentive strategies. Electricity prices along with the EV user preferences are taken into account for both charging (G2V) and discharging (V2G) operations, allowing for more realistic scenarios to be considered.

Smart Grid Technology

Electric vehicles were proposed as a good solution to solving energy crisis and environmental problems caused by the traditional internal combustion engine vehicles. In the last years due to the rapid development of the electric vehicles, the problem of power grid integration was addressed. In order to not put additional pressure onto the power grid several new technologies were developed. This chapter presents the smart grid technology, vehicle-to-grid concept, and electric vehicles grid integration. These technologies made possible the integration of electric vehicles without any major changes in the power grid. Moreover, electric vehicles integration brought new benefits to the power grid like better integration of renewable energy.

Bidirectional Power Flow

Abstract The increasing use of electrical vehicles aroused the problem of batteries charging and the consequent interface with the power grid. Commercial charging solutions are mostly based on unidirectional power flow converters; however, bidirectional power flow converters are an interesting solution when considering smart microgrid applications, with benefits in efficient energy use. In this context, the paper presents a bidirectional power flow converter for grid-to-vehicle (G2V) or vehicle-to-grid (V2G) applications. The conversion system is based on a three-phase voltage source inverter (VSI), which assures the grid connection with a unitary power factor. The direct current (DC) bus of the voltage source inverter is connected to a DC/DC converter that controls the battery power flow. This conversion system can operate in G2V mode when charging the battery or in V2G mode when working as an energy storage system and the power flow is from the battery to the power grid. The conversion system model is presented as well as the control strategy proposed. Simulation and experimental results showing voltages and currents in the circuit are also presented.
