The rapid growth of population, limited fossil fuel reserves, and their adverse effect on the environment compel a change over to alternate energy sources for electricity generation. Among such renewable sources, wind is the most prominent and sustainable energy source. Wind turbines operate by converting the kinetic energy available in wind as mechanical energy which can be later used for electricity generation. Although “large scale wind turbines” are commonly engaged to produce megawatts of power, they demand more space, involve high installation costs, and are unsuitable for residential purposes. An alternate approach is to use “Small-Scale Wind Turbines” which require less space, are cost-effective, and are quick to install. However, it is essential to properly model several parameters of small-scale wind turbines for efficient power extraction. This paper intends to design the parameters of a 1 kW small wind turbine to maximize power output by identifying the optimum tip speed ratio and considering the effect of a change in Reynolds number. From the derived observations, the performance characteristics of a small-scale wind turbine are analyzed.

Among different AC motors, the synchronous reluctance machines (SynRM) have been an attractive choice for automotive applications. In a typical inverter-fed AC drive system, the stator windings carry a current with a large harmonic content, resulting in an increased AC loss. This paper investigates the additional copper losses caused by non-sinusoidal currents. Aiming at loss minimization, different winding topologies are investigated for a 5-kW SynRM including rectangular hairpins and stranded wire. Additionally, unlike other studies, transient AC finite element modeling under highly distorted current is conducted at strand level for a better selection of the best magnet wire topology.

This paper presents improvement of power quality (PQ) in three-phase standalone system using generalized integrator observer (GIO) frequency locked loop (FLL) control algorithm, for three-phase self-excited induction generator (SEIG) driven by hydro turbine as a three-phase source feeding the sensitive/nonlinear/linear loads along a double stage solar PV-battery is integrated at the DC link, connected via a unified power quality conditioner (UPQC). The UPQC consists of two voltage source converters (VSCs) connected back to back at common DC bus. The series VSC of the UPQC is used for compensating voltage power quality and to maintain the harmonic free and constant amplitude voltage at load terminals, irrespective of any variation in the system. Moreover, the power qualities such as reactive power compensation, harmonics elimination, unity power factor corrections are provided by the shunt VSC of the UPQC, simultaneously while voltage power quality is improved. It significantly enhances the power quality at the generator terminals and ensures to adhere the mandate the IEEE-519 and the IEC-61727 standards even with either balanced or unbalanced loads. Moreover, by operating the SEIG below its rated voltage and maintaining the voltage across loads at its desired value, one can minimized the excitation current and hence the core losses.

A couple of hybrid electric vehicles (HEV) predominantly two-wheelers led to fire accidents, which will injure humans or lost their life. The probable cause of the fire is because of the non-isolation of abnormalities and instability in the charge and discharge cycle of electric vehicle batteries as a part of the battery management system (BMS). A battery is one of the sources of electrical energy, by using power electronic converters it can store or retain the electrical energy. Battery isolation is more important to protect against low output voltage or cell voltage and excessive charging current. The battery's charge level in perspective of its capacity is nothing but a state of charge (SOC). It is an important metric for evaluating battery storage systems. Because of the scalability and portability of cells along with inherent high charge-discharge cycles for the use of electric vehicles (EV), it is important to conFigure the isolated charging and discharging model (CDM) of batteries as a part of BMS. The growing number of electric vehicles improves the technological parameters of OBCs. Due to limitations in interior space availability, it has to keep in mind to incorporate the effective CDM into OBC. This paper developed the simulation circuit of an OBC with isolated CDM and the obtained results are analyzed.

Wireless power transfer (WPT) in air has been a research topic over a century and has been extensively used in applications such as electric vehicles (EV’s), mobile devices and RF identification (RFID) etc. Research of WPT in under water applications is more of interest because of attenuation to fields from water due to its salinity and water currents. In this paper a 1KW wireless power is transferred for autonomous under water vehicles (AUV’S) for charging the AUV battery. The eddy currents in water and their losses are considered for performance calculations. Simulation tools such as Ansys maxwell and LT spice is used for coil and circuit analysis respectively.

Electric vehicles are essential for the evolution of clean and green transportation. The crucial parts of vehicles that require energy are propulsion systems and charging systems. Therefore, the need of the hour is to develop high-power density, higher charging voltage levels, bidirectional operation to provide grid stability, higher operating frequency, and soft switching operation. Hence, this paper presents the design of a three-phase-threefold Dual Active Bridge (DAB) converter for a level three direct current charging station. The proposed converter interfaced with the prevailing distribution network at the input side and provides a dc link between the AC-DC converter and vehicle battery. Further, it covers the detailed design procedure to select various optimum components involved in the proposed DAB converter. As a result, it offers reliable power flow under different loading conditions and the inherent soft-switching operation. Finally, the proposed DAB converter is simulated for the power ratings of 5 kW, and the simulation results verify its working principle.

Permanent Magnet Synchronous motors (PMSM) are the special motors which are widely used in the applications of Electric Vehicles (EVs). Predictive current control (PCC) is the method which is popularly used for the control of PMSM. Generally, a two-level inverter is used to feed the PMSM in the mentioned process, but an Open -End Winding PMSM (OEWPMSM) fed from both the sides with two-level inverters will produce multi-level characteristics which gives lesser torque and flux ripples. In conventional PCC (C-PCC), the optimal voltage vector (OVV) is selected by calculating the error between reference value stator current and predicted value of stator currents. Here, the same OVV is selected for an entire control interval and hence there are more ripples. In the proposed PCC, a null vector is included with OVV which is for only certain time in control interval known as duty cycle. The proposed PCC has developed with improved cost function which includes flux weights and duty cycle calculations and gives the current error value more accurately to minimize the ripples in torque & flux. Simulation studies are performed for an OEW-PMSM fed with dual inverter with three level inversion for conventional and proposed PCC.

Induction motors (IM) are commonly utilized as the prime movers in various industrial applications because of their simplicity, reliability, and minimal maintenance cost. Fault diagnosis of IM is one of the primary issues that seeks to make sound maintenance decisions to preserve a system's integrity and safety while reducing unplanned downtime and lowering maintenance costs. Most fault diagnosis approaches for IMs are based on analyzing vibration signals captured at constant rotating conditions. Those vibration signal-based methods are less capable at under-speed varying conditions. This paper proposed a Passive Thermal Imaging (PTI) based fault diagnosis approach for IM at varying speed conditions to deal with these issues. Firstly, various thermal image frames are extracted from the captured thermal video from the healthy and faulty IM at varying speed conditions. Thereafter, Residual Network (ResNet) is used for extraction of features, followed by further classification using Support Vector Machine (SVM) at various fault conditions. The findings demonstrate that the suggested technique outperforms traditional vibration-based methods in identifying various IM faults at varying speed conditions.

A renewable energy source (RES) interfaced with utility grid and AC plug-in electric vehicle (PEV) charging station is designed here, as the electric vehicles replacing conventional fossil-based vehicles and supporting green concept is growing tremendously. Local loads as well as PEV loads are connected at common AC bus of the system. Sources are interfaced to AC bus using voltage source converters (VSC). With the large scale integration of electric vehicle and renewable energy sources to the utility grid, there is always a challenge to build up an adaptable and robust control due to intermittent nature and dynamics. Thus, two low pass filters with adaptive noise cancellation algorithm forming as pre-filter and second order generalized integrator frequency locked loop (ALS-FLL) control strategy are used for power flow management, power quality mitigation, voltage regulation, power factor correction. Moreover, the system also feed local loads under dynamic conditions and serves as a PEV charging station. The presented topology is simulated in MATLAB Simulink platform under various perturbations to obtain the effective response of the system.

An Air conditioner is mostly used in tropical countries and power-hungry load. The energy consumption of air conditioner increases with rise in the solar irradiation. Therefore, in this paper, an energy management scheme is given to reduce the pressure on the utility grid during the peak hours with the help of photovoltaic (PV) and battery energy storage (BES) integration using the bidirectional dual active bridge (DAB) converter. With recent advancement in semiconductor technology and drives, the air conditioning systems are manufactured with variable frequency drive (VFD) technology. Because of the diode bridge rectifier (DBR), connected at the front end of the VFD the current drawn at the input side is non sinusoidal and peaky in nature. Due to the high power demand, the amplitude of the peak current is significantly high, which deteriorates the power quality of the system. In this paper, this problem is addressed by incorporating a power factor corrector (PFC) boost converter and modulated at unity power factor so that the waveshape of the grid current is maintained sinusoid with low THD. Moreover, the excess generation of the PV array is fed back to battery during the off-peak hours of air conditioner.
