“…The batteries, apart from supplying energy to EVs, can also act as energy storage systems (ESS) for the grid. Charging the batteries in the hours of less energy demand (off-peak hours) and then providing that energy in the periods with higher demand [30][31][32] enables to make the energy demand curve flatter, with the benefits that this entails [33][34][35][36][37]. According to the International Renewable Energy Agency (IRENA), using ESSs would reduce energy installation costs between 50 % and 66 % (see Fig.…”

Emission of greenhouse gases and scarcity of fossil fuels have put the focus of the scientific community, industry and society on the electric vehicle (EV). In order to reduce CO 2 emissions, cuttingedge policies and regulations are being imposed worldwide, where the use of EVs is being encouraged. In the best of scenarios reaching 245 million EVs by 2030 is expected. Extensive use of EV-s requires the installation of a wide grid of charging stations and it is very important to stablish the best charging power topology in terms of efficiency and impact in the grid. This paper presents a review of the most relevant issues in EV charging station power topologies. This review includes the impact of the battery technology, currently existing standards and proposals for power converters in the charging stations. In this review process, some disadvantages of current chargers have been identified, such as poor efficiency and power factor. To solve these limitations, five unidirectional three-phase rectifier topologies have been proposed for fast EV charging stations that enhance the current situation of chargers. Simulation results show that all the proposed topologies improve the power factor issue without penalizing efficiency. The topologies with the best overall performance are the Vienna 6-switch and the Vienna T-type rectifier. These two converters achieve high efficiency and power factor, and they allow a better distribution of losses among semiconductors, which significantly increase the life-cycle of the semiconductor devices and the reliability of the converter.

“…For these reasons, it is estimated that there will be an exponential increase in the usage of PHEVs. The role of PHEVs and its popularity for the application in a smaller scale power system called microgrid is discussed in [6], where the power exchange was controlled by the aggregator of PHEVs by coordinated scheduling [7]. It is observed in the literature that the concept of aggregator as a single point of communication contact with the available fleet of PHEVs is the optimised way to handle and communicate with them.…”

This paper proposes a distributed resource management scheme to avoid the need for energy storage and achieve the required frequency regulation. The energy sources considered in the microgrid are Solar PhotoVoltaics (SPV), Diesel Generators (DG), Fuel Cells (FC) and Plug-in Hybrid Electric Vehicles (PHEV). The frequency regulation is done by considering the SPV operation at a Limited-Power-Point (LPP) for spinning reserve using neurofuzzy control in coordination with PHEVs and other sources. In vehicle-to-grid (V2G) mode, State of Charge (SOC) of the battery in a PHEV shall be the deciding factor in allowing it to participate in the regulation. A simple additive-adaptive strategy based algorithm is proposed and tested in the isolated microgrid environment. Satisfactory results of frequency regulation were obtained upon consideration of scenarios, varying the load and insolation in steps.

“…Since the renewable sources are fluctuated, the suited energy storage buffer is needed to preserve the power supplying quality. For the micro-grids with medium and small ratings, the battery is the most popularly employed device [4,5]. By augmenting the energy type storage device of battery with the suited power type devices of flywheel [6] and/or SC [7,8] is beneficial in having better compromised operation performance.…”

This paper presents the establishment of a small DC microgrid incorporating with electric vehicle (EV) as a movable energy storage source. The developed micro-grid consists of wind permanent-magnet synchronous generator (PMSG) and photovoltaic (PV) source, battery/super-capacitor/flywheel hybrid energy storage system and grid-connected single-phase three-wire load inverter. Through properly design and control, good operation performances are preserved. And the microgrid-to-grid (M2G) and G2M can be successfully conducted with good power quality. As to the developed EV interior permanent-magnet synchronous motor (IPMSM) drive, the super-capacitor (SC) auxiliary storage is equipped to assist the battery source in intermittent energy conversion. Satisfactory acceleration/deceleration/reversible and regenerative braking operation characteristics are obtained, and the successful microgrid-to-vehicle (M2V) and V2M interconnected operations of the EV and micro-grid are achieved.
