“…This control strategy is deployed in the single stage converter of the FCS [23,44]. This approach uses only a rectifier for the desired output voltage [57,74]. This strategy is used where control simplicity and component count reduction are desired [59,74].…”

“…This approach uses only a rectifier for the desired output voltage [57,74]. This strategy is used where control simplicity and component count reduction are desired [59,74]. It traditionally allows a mixture of either feedforward, feedback, direct power or current control strategy, which regulates the grid-side instantaneous current and voltage using a single rectifier [75].…”

“…One of the examples of SSC control techniques is shown in Figure 11. This technique consists of a rectifying converter [74] that is implemented to mimic the virtual synchronous machine's (VSM) behavior [76]. However, the report in [77] proposed an interleaved switching strategy for rectifier control using the PI controller for current control to ensure the reduction in the magnitude of the ripple current injection.…”

“…This control strategy was able to maintain the soft switching of both AC-side and DC-side switches across the voltage grid cycle at the PCC for different load conditions [75,78]. However, a major drawback of a slow response was observed in [74,78] under increased EV loads, but this shortcoming was suggested to be due to the PI controller [74][75][76]. In the case of VSM, as shown in Figure 12, where it is deployed to mimic a VSM's performance, it offers a controlled power factor and stabilized supply frequency irrespective of changes at the PCC [80].…”

The growing trend for electric vehicles (EVs) and fast-charging stations (FCSs) will cause the overloading of grids due to the high current injection from FCSs’ converters. The insensitive nature of the state of charge (SOC) of EV batteries during FCS operation often results in grid instability problems, such as voltage and frequency deviation at the point of common coupling (PCC). Therefore, many researchers have focused on two-stage converter control (TSCC) and single-stage converter (SSC) control for FCS stability enhancement, and suggested that SSC architectures are superior in performance, unlike the TSCC methods. However, only a few research works have focused on SSC techniques, despite the techniques’ ability to provide inertia and damping support through the virtual synchronous machine (VSM) strategy due to power decoupling and dynamic response problems. TSCC methods deploy current or voltage control for controlling EVs’ SOC battery charging through proportional-integral (PI), proportional-resonant (PR), deadbeat or proportional-integral-derivative (PID) controllers, but these are relegated by high current harmonics, frequency fluctuation and switching losses due to transient switching. This paper reviewed the linkage between the latest research contributions, issues associated with TSCC and SSC techniques, and the performance evaluation of the techniques, and subsequently identified the research gaps and proposed SSC control with SOC consideration for further research studies.
