Solar electric vehicle (SEV) is an emerging transport utility, which primarily uses solar energy for its propulsion. It is regarded as an ideal solution for clean and sustainable transportation. This article presents an approach to investigate the reliability and availability of a SEV facilitated with a standby plug-in option. A composite reliability model is developed in Markov framework incorporating the stochastic failure and repair characteristics of all critical electrical systems of the vehicle, namely, power supply system, energy storage system, motor-drive system, controllers, and energy management system. A new probabilistic index is proposed to determine the availability of power generated by the photovoltaic modules mounted on the SEV. This index can be treated as a useful parameter for designing area-specific reliable SEV models. The reliability improvement due to the standby plug-in facility is also examined. The study quantitatively justifies that a SEV with a plug-in facility is much more reliable and effective than a regular plug-in EV. The article also illustrates some novel concepts which can support further research on new reliability design and maintenance of a SEV.List of Symbols and Abbreviations: G, Solar irradiation; G std , Standard solar irradiation; G ref , Reference solar irradiation; T max , Maximum temperature; T min , Minimum temperature; α, Temp. coefficient of PV arrays; P max , PVG capacity; P mup , minimum useful power; r sw , reliability of the changeover switch; R PVG , Reliability of the PVG; A PVG , Availability of the PVG; λ PVS , FR of the PVS; μ PVS , RR of the PVS; λ PVG , FR of the PVG; N i , No. of SEV at i th CS; U i , interruption time per year at i th CS; λ c , FR of the converter system; μ c , RR of the converter system; R CS , Reliability of the CS; A CS , Availability of the CS; λ CS , EFR of the CS; R PSS , Reliability of the power supply system; r SW , Reliability of the change-over switch; Q, truncated matrix; λ 1 , discharging rate of battery; μ 1 , charging rate of battery; λ B , EFR of the battery; μ B , ERR of the battery; A B , Availability of the battery; λ CC , EFR of the charge controller; μ CC , ERR of charge controller; A CC , Availability of charge controller; A ESS , Availability of the ESS; λ ESS , EFR of the ESS; μ ESS ,

“…The authors of [27] have proposed a conventional PI controller to enhance the power quality of a multilayer single-phase inverter. The authors of [28,29] have stressed that voltage sag is a frequent problem that often results in unnecessary tripping when applied to a single-phase system operating in both ON and OFF grid modes. In addition, in an earlier study [30], the authors use a PV system to solve a problem related to the efficient control of the reactive power caused by using loads that influence the current supplied from the source.…”

The main aim of the research work presented in this paper consists of proposing an effective control scheme for a grid-connected single-phase photovoltaic (PV) system to enhance not only the power quality at the point of common coupling (PCC) but also to operate with a maximum power point tracking (MPPT) controller. Moreover, an orthogonal signal generator (OSG) module for effective grid synchronization, a current reference generation controller, and a PWM generating block have also been designed and included in this paper. The proposed control strategy allows the MPPT controller to switch to faulty mode and maintains the voltage according to network requirements using an adaptive neuro-fuzzy inference system (ANFIS)-based control whenever a fault occurs at the PCC. The performance of the analyzed control strategy, which is based on the static compensation of the DC-link voltage fluctuations in a grid-connected inverter powered by PV, is further explored through simulations in MATLAB, and the results are included in this paper. Moreover, the control scheme is implemented experimentally using a dSPACE DS 1104 control board and then assessed on a small laboratory-scale single-phase PV system that is subjected to some fault scenarios. The simulation and experimental results have shown improved power quality and robustness against grid fluctuations, resulting in better dynamic performance.

“…A multilevel single phase inverter using PI controller is used to improve power quality in [15]. Voltage sag occurrence is a common issue which may cause unnecessary tripping in the case of a single phase system that is working in grid connected or islanded mode [16][17]. To address the reactive power control issue caused by the use of loads which affects the current being drawn from the source, a PV system is used in [18].…”

The current grid standards for the single-phase residential PV system expect it to operate at Maximum Power Point Tracking (MPPT) mode under normal operating conditions and to maintain the voltage profile whenever a grid fault occurs. The proposed system supplies power to the load under stable conditions and the PV system works in MPPT mode. When the fault occurs at the Point of Common Coupling (PCC) and the voltage is reduced, the proposed controller maintains the voltage profile by injecting the current fed by the current controller at the PCC. The controller shifts from MPPT to the faulty mode and maintains voltage as per grid requirements. During islanding conditions, the PV system successfully caters to the requirements of the load by shifting the control from MPPT to islanding mode. When the PV system is in operation the power quality is enhanced
