Adoption rate of Electric Vehicles (EVs) is highly influenced by charging infrastructure. Onboard battery chargers are preferred to recharge the battery packs installed in low power EVs. This paper presents a two-stage five-level rectifier based on-board charger for EV charging application. The proposed five-level rectifier constituted by six active switches capable to produce five distinct voltage level which reduces the size of filter and improves the power quality. The control scheme and the operating states for the rectifier are presented in detail. With the applied control scheme, the rectifier is capable to achieve unity power factor for all output voltages and regulated output voltage at the charging port. The proposed battery charger is capable to attain high efficiency which can ultimately make it suitable to work in integration with utility grid.

A nonlinear Sigma point Kalman filter known as Central Difference Filter which considers only first order Taylor series approximation with the help of interpolation formula, have been employed here for the first time during dynamic state estimation of power systems states. This paper also exhibits a comparative performance analysis of two estimation techniques namely Central difference filter (CDF) and Cubature Kalman filter technique (CKF) during power systems dynamic state estimation. The estimation is performed employing measurements from Remote terminal units (RTU) and Phasor measurement units (PMU). The whole simulation process is carried out for IEEE 30 bus test system. Holts two parameter linear exponential technique which often utilized as a state forecasting technique has been used here to forecast the systems state at the prediction step. The superiority of CDF over CKF, has been illustrated here on context of computation time and estimation accuracy.

In recent years, microgrids have become more prominent in power systems, which means the existing conventional protection schemes must be approached with caution while using them for micro-grid protection. Presently available micro-grid protection techniques bank on features extracted from the extreme ends of the feeder to recognize any fault but do not provide any information regarding the status of in-line feeders. The scheme presented in this paper incorporates a light GBM classifier to identify the fault and give information about the faulty feeder section. Discrete Fourier Transforms (DFTs) have been used for previewing the time-synchronized measurements. For simplicity, the statistical features were computed from DFT coefficients and used as input features. A standard IEC 61850-7-420 microgrid incorporating renewable distributed generators (DGs) has been used to perform simulation studies by varying different operating conditions. The proposed methodology has been validated by the results illustrated.

This article presents a method for model order reduction (MOR) of Cuk converter in discrete domain. The MOR is obtained using time moments (TMs) and Markov parameters (MPs) matching. For this purpose, the expressions of TMs and MPs are derived in discrete domain. The state space averaging (SSA) method is exploited to compute transfer function of converter. Test system is included to illustrate the methodology of MOR. In the test case, the fourth-order system is reduced to first-order, second -order, and third -order models. To signify the efficacy of the method, step and impulse response are plotted for system and models. For a equitable comparative study, time domain specifications for lower limit (LL) and upper limit (UL) are presented. The results presented prove the effectiveness and applicability of the proposed method.

Renewable energy-based battery charging systems for Electric Vehicles (EV) have seen surge in automotive research in last few years. Solar PV-fed EVs are thoroughly examined in this research. Among the many benefits of using batteries to store energy in ground vehicles include zero emissions, load levelling, excellent transient functioning, and ability to recover energy while braking. To meet these criteria, bidirectional DC-DC converter is needed to connect PV to battery's dc-link. A PV-powered electric vehicle must be able to operate in two distinct modes: charging and discharging. Maximum Power Point Tracking (MPPT) technique is utilized in this study to harvest most power by solar PV. In addition, DC-DC converter with bidirectional output requires closed-loop control circuit which is proposed in this paper. MATLAB simulations are used to confirm system's efficacy.

Carbon monoxide is a common byproduct of incomplete combustion of carbon materials. It is a toxic gas that causes headaches, nausea, and dizziness, as well as death in some cases. As a result, human safety and security in the presence of CO are critical. Apart from detection, designing a recommendation system for a long time carbon monoxide inhalation has, therefore, become very much vital to avoid such severe incidents. This paper proposes and implements a recommendation system for each specific interval of time so that users must beware of each time interval of CO inhalation. This recommendation system can be used in medical diagnosis by the doctor during any health-related issue. The proposed system in this research paper creates storage on ThingSpeak channels that constantly updates the data from the CO sensors on the concentration of the CO gas. After that, continuous IoT analytics through MATLAB on Thingspeak sends a health recommendation for each specific time interval. This recommendation is made throughout the days hence behaves as an advisory system. Also, in this system, for a limited purpose, a specific alert message system is added through the IFTTT web service when the concentration of CO goes beyond the threshold value.

Solar photovoltaic (PV) systems are becoming increasingly popular across the world, and the Modular Multilevel Converter (MMC) architecture emerged as an appealing option for PV integration. The MMC topology has been conceived to alleviate the inconveniences of traditional multilevel converters, such as the higher-order level capacitor balance problem, the necessity for power filters and interface transformers. Because of its inherent benefits, MMC is used as the interface between diverse energy resources. Here, the PV is integrated with maximum power point tracking into the three phase three level MMC. When it comes to maintaining output power quality, modulation methods are significant. The proposed capacitor voltage balancing algorithms use phase disposition pulsewidth modulation (PDPWM) and space vector modulation (SVM) schemes to ensure the balancing of the capacitors in each sub-module. The MATLAB/Simulink simulation is performed and the effectiveness of the control approaches is evaluated.

This paper deals with robust control strategy used for the power management of a DC microgrid. The DC mi-crogrid considered here comprises of a PV source, permanent magnet synchronous generator based wind system, hybrid storage combination of battery and supercapacitor and a DC load. The PV and wind systems are operating at maximum power point during normal operation. PV is operating in MPPT using P & O algorithm and wind is operating using optimum torque based algorithm. A control strategy has been proposed for power sharing between storage systems and renewable sources. This strategy uses the Lyapunov function and ensures global asymptotic stability of the closed loop system. The bypassing of high frequency components to supercapacitor in the control strategy helps in reducing the current stress occurring in the battery. A robust controller based on sliding mode is used for tracking the current reference in the wind energy system. A power management algorithm has been developed based on this control technique for balancing the power, when there is a change in the renewable input, SoC of storage systems or load. During these disturbances, the DC link voltage is tightly regulated. The effectiveness of this strategy is explored by formal analysis and simulation using MATLAB/Simulink.
