“…For PV charging stations connected to grid, the isolated configuration is the favorite one as it operates in high voltage levels and could provide a galvanic isolation between Alternative current part and direct current part of the system . [37], [38]. The key constrained point of the inverter design is the frequency stabilization.…”

Abstract.Within the next few years, Electrified vehicles are destined to become the essential component of the transport field. Consequently, the charging infrastructure should be developed in the same time. Among this substructure, Charging stations photovoltaic-assisted are attracting a substantial interest due to increased environmental awareness, cost reduction and rise in efficiency of the PV modules. The intention of this paper is to review the technological status of Photovoltaic-Electric vehicle (PV-EV) charging stations during the last decade. The PV-EV charging station is divided into two categories, which are PV-grid and PVstandalone charging systems. From a practical point view, the distinction between the two architectures is the bidirectional inverter, which is added to link the station to the smart grid. The technological infrastructure includes the common hardware components of every station, namely: PV array, dc-dc converter provided with MPPT control, energy storage unit, bidirectional dc charger and inverter. We investigate, compare and evaluate many valuable researches that contain the design and control of PV-EV charging system. Additionally, this concise overview reports the studies that include charging standards, the power converters topologies that focus on the adoption of Vehicle-to grid technology and the control for both PV-grid and PV standalone DC charging systems.

“…Some modified droop controllers have been presented recently to further enhance the voltage quality and stability of DC grids [22][23][24][25][26][27]. In [22], an improved decentralized DC power management strategy based on P-Vdc 2 droop is designed to enhance the dynamics of DC power regulation. In [23], a droop controller suitable for multitime scale power control is presented to realize proper power interaction among different sub-grids.…”

“…The controller strategy proposed in this paper solves the problems of rise in DC bus voltage, overcharge, and over discharge of the storage elements. In Reference, a decentralized coordination control method for the parallel bi‐directional power converters in a grid‐connected microgrid is proposed. The control strategy employed in this proposed system makes the bi‐directional power converters operate in coordination and provide voltage support for the DC microgrid.…”

This paper proposes a low voltage (400 Vdc) distributed renewable energy fed DC microgrid structure for a residential system, which uses DC voltage for the electronic appliances. The distributed energy sources—solar photovoltaic (PV) and wind energy are considered as input sources. The output power from these sources is stochastic in nature. An efficient energy management and switching circuit is designed to control the power flow from the sources with a high gain DC‐DC converter as the main component. The output power regulation is achieved by means of controlling duty ratios of the switches in the proposed high gain converter through PI controller. The control algorithm effectively converts the unregulated DC power from the solar PV and wind into regulated DC for driving a DC load connected in DC‐microgrid. The energy management and switching circuits account for seamless operation of the DC microgrid under various modes when one or all the sources and loads are connected directly at the DC grid link. The designed energy management and switching circuit also ensures the power balancing in the proposed system. The proposed DC microgrid structure is simulated using MATLAB Simulink. The performance of the proposed high gain converter for the DC grid link voltage regulation is analyzed under source power variation and dynamic changes in load for various operating conditions. The proposed DC microgrid structure is validated using simulation results.
