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.

“…From the above expression (28), it is inferred that the state variable for inverter output voltage depends on the modulation index and the input DC voltage. This paper concerns on a constant input DC voltage for the inverter via the DC-Link capacitor is ensured; hence, the adjustments of M is the predominant control parameter of the Sinusoidal Pulse Width Modulation (SPWM) in maintaining the RMS value of the AC output voltage.…”

Solar photovoltaic (SPV)-based single-phase inverters are universally accepted and commercially utilized renewable power converter system. Generally, the magnitude of the inverter output is perturbed on load variations, and the intermediate DC-DC boost converter output is perturbed because of the solar availability. The main intermediary component is the DC-Link capacitor. The regulation of DC-Link voltage is the key factor in maintaining the stability of the system with bilateral power converters. In the existing methods, individual Sliding Mode Control (SMC) are used to maintain the stability of the converters independently. However, the individual SMC's do not have any corelated control to address the common problem of DC-Link voltage regulation. This paper proposes an alternative solution with Coupled SMC (CSMC) to address the problem of regulating the DC-Link voltage. Both the Boost-SMC and Inverter-SMC are individually developed and controlled in a unified approach by having mutual adjustments in the converter and inverter switching pulses. The CSMC strategy is developed in Matlab and experimented using dSPACE-MicrolabBox. The validation tests are compared with conventional SMC, which shows the betterment of CSMC in robustness and waveshape tracking.

The Solar PhotoVoltaic (SPV) systems are the trending and commercially reputable power source abundantly served by the nature to the mankind. Partial Shading Conditions (PSC) are one of the critical concepts in the SPV maximum power extraction. PSC’s are nonlinear and fuzzy in its attributes, as it is unpredictable. Hence, it has numerous Local Maximum Peak Power (LMPP) points. Although, a wide spread of Maximum Power Point Tracking (MPPT) algorithms are doing justice in locating the peak power points and stabilize the system, they are inadequate to locate the LMPP’s and the Global Maximum Peak Power (GMPP) point. This paper proposes a discrete time-based Slime Mould Optimization (SMO), providing an effective support to the buck converter based MPPT controller for SPV systems. The analysis and testament of buck converter in discrete domain alleviates the optimization in discrete samples, which accelerates the computation speed in locating the LMPP and GMPP. The proposed methodology is validated from the predominant parametric results like tracking time, power efficiency and the stability of the system under various PSC’s. The experimental implementations are performed in MATLAB simulations and experimented with dSPACE-MicroLabBox.
