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 study in [25] focuses on the performance of the power conversion system performance among four topologies and on estimating the SoC of a lithium-ion cell by combining two methods: Coulomb and open circuit voltage measurement. The study in [26] focuses on testing the reliability of BESS, based on Markov models. The BESS models focus on the electrochemical model, the analytical model, and the substitute circuit model [27,28].…”

A virtual power plant (VPP) can be defined as the integration of decentralized units into one centralized control system. A VPP consists of generation sources and energy storage units. In this article, based on real measurements, the charging and discharging characteristics of the battery energy storage system (BESS) were determined, which represents a key element of the experimental virtual power plant operating in the power system in Poland. The characteristics were determined using synchronous measurements of the power of charge and discharge of the storage and the state of charge (SoC). The analyzed private network also includes a hydroelectric power plant (HPP) and loads. The article also examines the impact of charging and discharging characteristics of the BESS on its operation, analyzing the behavior of the storage unit for the given operation plans. The last element of the analysis is to control the power flow in the private network. The operation of the VPP for the given scenario of power flow control was examined. The aim of the scenario is to adjust the load of the private network to the level set by the function. The tests of power flow are carried out on the day on which the maximum power demand occurred. The analysis was performed for four cases: a constant value limitation when the HPP is in operation and when it is not, and two limits set by function during normal operation of the HPP. Thus, the article deals not only with the issue of determining the actual characteristics of charging and discharging the storage unit, but also their impact on the operation of the entire VPP.
