“…Furthermore, advanced controls like hierarchical control architecture, fuzzy control architecture, and multi-agent-based control architecture can be used for maintaining voltage fluctuations. The limited capacity of the energy storage system is necessary to overcome fluctuation of DC Bus voltage and maintain power balance [72,[75][76][77][78].…”

The usage of electric vehicles (EV) has been increasing over the last few years due to a rise in fossil fuel prices and the rate of increasing carbon dioxide (CO2) emissions. EV-charging stations are powered by existing utility power grid systems, increasing the stress on the utility grid and the load demand at the distribution side. DC grid-based EV charging is more efficient than AC distribution because of its higher reliability, power conversion efficiency, simple interfacing with renewable energy sources (RESs), and integration of energy storage units (ESU). RES-generated power storage in local ESU is an alternative solution for managing the utility grid demand. In addition, to maintain the EV charging demand at the microgrid levels, energy management and control strategies must carefully power the EV battery charging unit. In addition, charging stations require dedicated converter topologies, control strategies, and need to follow set levels and standards. Based on EV, ESU, and RES accessibility, different types of microgrid architecture and control strategies are used to ensure optimum operation at the EV-charging point. Based on the above said merits, this review paper presents different RES-connected architecture and control strategies used in EV-charging stations. It highlights the importance of different charging station architectures with current power converter topologies proposed in the literature. In addition, a comparison of microgrid-based charging station architecture with its energy management, control strategies, and charging converter controls are also presented. The different levels and types of charging stations used for EV charging, in addition to controls and connectors used, are also discussed. An experiment-based energy management strategy was developed to control power flow among the available sources and charging terminals for the effective utilization of generated renewable power. The main motive of the EMS and its control is to maximize the usage of RES consumption. This review also provides the challenges and opportunities in EV-charging, and parameters in selecting appropriate charging stations.

A high-frequency multi-port (HFMP) direct current (DC) to DC converter is presented. The proposed HFMP is utilized to interface a photovoltaic (PV) system. The presented HFMP is compact and can perform maximum power point tracking. It consists of a high-frequency transformer with many identical input windings and one output winding. Each input winding is connected to a PV module through an H-bridge inverter, and the maximum PV power is tracked using the perturb and observe (P&O) technique. The output winding is connected to a DC bus through a rectifier. The detailed analysis and operation of the proposed HFMP DC-DC converter are presented. Extensive numerical simulations are conducted, using power system computer aided design (PSCAD)/electromagnetic transients including DC (EMTDC) software, to evaluate the operation and dynamic behavior of the proposed PV interfacing scheme. In addition, an experimental setup is built to verify the performance of the HFMP DC-DC converter.

This paper presents a non-isolated DC–DC boost topology with a high-voltage-gain ratio for renewable energy applications. The presented converter is suitable for converting the voltage from low-voltage sources, such as photovoltaic panels, to higher voltage levels. The proposed converter consists of a multiphase boost stage with an interleaving switching technique and a voltage multiplier cell to provide a voltage level at a reduced duty cycle. The interleaved boost stage consists of two legs and can be either fed from single or multiple voltage sources with the ability to control each source separately. The voltage multiplier cell can increase the voltage level by charging and discharging the capacitors. Several advantages are associated with the converter, such as reduced voltage stress on semiconductor elements and a scalable structure, where the number of voltage multiplier cells can be increased. The inductors in the interleaved boost stage share the input current equally, which reduces the conduction loss in the inductors. The input and the output of the converter share the same ground, and all active switches are low-side, which means no feedback or signal isolation is required. The theory of operation and steady-state analysis of the converter operating in the continuous conduction mode is presented. Components selections and efficiency analysis are presented and validated by comparative analysis and simulation results. A 0.195 kW experimental prototype was designed and implemented to convert the voltage from 20 V input source to 400 V output load, at 50 kHz. The test results show a high-performance of the converter as the maximum efficiency point is above 97%.
