The need for energy conservation and environmental protection have triggered the development and deployment of electric vehicles. Light electric vehicles and fossil fuel based light vehicles are popular means of transport for short distances in not only remote rural areas but also in places of tourist attractions. For Islands in the tropical belt like the Sunderbans in India and other pristine sea beaches in South East Asia where nature is luxuriantly present, green transportation is proposed in this work. The objective is to develop environment friendly transport for these natural havens and islands that have ample renewable resources especially in the form of solar power. In this work, a model of a light electric vehicle is developed that utilizes the solar energy during the daytime for charging its batteries. Battery charge controller inbuilt with boost based MPPT (Maximum Power Point Tracking) of solar irradiation have especially been designed to meet the requirements. The efficiency of the designed MPPT is studied. As accumulation of dust and sand reduces the solar module efficiency, an automated self-cleaning mechanism has also been designed that automatically cleans the solar panel regularly. The life cycle cost and the reduction in carbon emissions coupled with the Cost of Capital Investment and operating expenses of the developed model of green transportation far outweighs the similar values obtained from other modes of remote transportation.

Renewable and clean energy has been on the global energy transition agenda for a while but has lately gained momentum due to ambitious climate targets. As hydrogen is a clean energy carrier, many nations have recognised the value of the hydrogen economy in lowering emissions from hard-to-abate sectors. Countries around the world have recently published national hydrogen strategies outlining the intent to support the transformation to hydrogen, emphasising country-specific areas of interest, and examining regulatory obstacles and market opportunities. The strategic hydrogen road-map is necessary to boost the hydrogen economy. In this context, this paper presents a short review of the various production pathways and market opportunities for hydrogen. Additionally, the paper summarises the future targets and the design of the national hydrogen strategies of a few nations like Australia, the United States, the European Union, the United Kingdom, Germany, and Norway. As India has also set ambitious targets of achieving net-zero by 2070 and 5 million tonnes green hydrogen production by 2030, this work presents the strategic framework adopted by the nation and future recommendation to achieve a hydrogen economy.

Permanent magnet synchronous machine is a compact and efficient machine with advantage of high energy density. In present scenario, the industrial use of permanent magnet machines increases tremendously. Therefore, condition monitoring and fault diagnosis of PMSM gaining more and more attention. This paper presents a study to address eccentricity and demagnetization faults in rotor of permanent magnet machines using FEM (Finite Element Method) in Ansys Mexwell-2D Environment. In context to PMSM faults, eccentricity faults accounts for nearly 10% of total faults of the machine. In present investigation, the eccentricity faults study is carried out to different level of severities ranging 10-40% and the radial components of airgap flux density spectrum of every severity level including its FFT is compared with healthy machine spectrum. The design process includes imperative assumptions and evaluates machine parameters. The design incorporates V-type magnet structure and NdFeB (N42) to utilize as rare earth material. The analysis results determine the effectiveness of anticipated machine design.

The incorporation of plug-in electric vehicles (PEVs) in a micro-grid system can play a major role in load frequency control (LFC) with an appropriate charging/discharging process. This paper presents LFC in micro-grid system (diesel-wind-photovoltaic) utilizing PEV as a separate source. A cascaded proportional-integral-derivative (PID) controller is adopted to control the frequency response of the micro-grid system. The controller parameters are optimized by using a hybrid bacterial-foraging-oriented particle-swam-optimization (BFO-PSO) technique. The results of the proposed cascaded PID-based control scheme are compared with that obtained by other conventional controllers, and the computational performance of the hybrid BFO-PSO is compared with the widely used PSO. The proposed hybrid BFO-PSO tuned cascaded PID control scheme is validated with satisfactory results.

This paper aims to check the voltage and frequency response of a single-phase solar PV grid inverter with an output of 4 kW in the event of over / under voltage and over/under frequency fluctuations. The inverter voltage and frequency performance are verified against compliance with IS/IEC 61727: 2004 (Indian standard) and the proposed method. The study shows that in the event of an abnormal grid frequency with a deviation of ± 1.5 Hz, the grid-connected inverter trips within limits and meets the requirements of the standard and the proposed method. In contrast to the abnormal frequency condition, the inverter has exceeded the 0.1-second limit during an abnormal voltage condition (under-voltage at 105 V). The proposed method is validated, and the results are provided.

This paper presents a new topology of transformer-less inverters (TLI) for photovoltaic (PV) applications. It is based on the common ground configuration (CGC). CGC TLI has an inherent ability to reduce the leakage current (LC), one of the principal issues. This uses eight switches, two switched capacitors (SC) and a dc linked capacitor to generate the 5-level double-boosted output voltage. This inverter is suitable for grid integration of PV voltage that is lower than the grid voltage because of the boosting capability. The SCs are self-balanced by charging and discharging at a fundamental frequency. The Inverter control is accomplished by level shift pulse width modulation (LS-PWM). Further, component selection procedures and comparative studies are carried out. The performance of the topology is further verified on MATLAB/Simulink.

As water and energy grids are highly interconnected, water-energy nexus (WEN) is considered an attractive target for malicious attackers. Attacking WEN affects both systems simultaneously; consequently, the attack is able to create fatal damage in the entire network. In this paper, we propose to tackle this problem using different deep learning models with different loss functions. Additionally, a mixed-integer nonlinear programming (MINLP) WEN in presence of renewable energy sources model is reformulated into a mixed-integer linear programming model for real-time implementation purposes. The optimization model is developed using MATALB, and the deep-learning models are implemented using Python keras framework.

This research paper discusses about design of phase lock loop (PLL) for grid connected inverter under the presence of different non-idealities. In most applications, the ability to detect the grid voltage phase angle is a crucial component of control, especially when synchronizing the current injected by grid-connected solar inverters. It is very important to track an accurate phase angle, frequency, and amplitude for the proper functioning of the grid connected inverter. This research article mainly deals with synchronous reference frame (SRF) PLL design using proportional integral (PI) controller and fuzzy logic based intelligent controller under both ideal and abnormal grid voltage conditions. The proposed model is designed and tested in MATLAB/Simulink. Obtained outputs are contrasted with the conventional PI controller and the fuzzy logic controller proposed. Simulation results shows the Fuzzy logic-based controller has a better accuracy when compared to PI controller for non-ideal grid conditions.

Generation and load are increasing gradually; distribution systems are facing additional complications with the increase in load demand and incorporation of distributed generators. The inactive distribution systems getting changed into active distribution systems. Nowadays, identifying faults becomes tough job and causes a lot of inconvenience to consumers. Therefore, there is a need for a real-time model to monitor the distribution networks. State estimation can be an effective method to build realistic models, mainly for non-linear and highly unbalanced systems like the distribution grid. This paper presents hybrid state estimation which has non-linear state estimation using Remote Terminal Units data and linear state estimation with the optimal number of Phasor Measurement Units data in an active distribution networks. The occurrence of Fault in the system is identified whenever the change in voltage at any bus is more than change in voltage threshold value at that bus. Further, faulty section has been identified by observing voltage profile obtained from linear state estimation procedure. IEEE 33 bus test system taken for validation of results.

DC Microgrids have become more and more popular due to their wide range of applications in the modern world. In the context of domestic rural electrification applications standalone Low voltage DC (LVDC) microgrids have been quite popular in recent times. With the absence of grid support in standalone systems, voltage stability and energy management are two crucial aspects to be handled. This paper, therefore, presents an effective cost-driven energy management framework (EMF) for the effective utilization of resources with a minimal overall cost of the system. The proposed EMF manages the storage resources effectively and correspondingly modifies the control references to the respective control units of the storage. The cost function corresponding to the system has been framed with due inclusion of the operation and maintenance cost of the different storage units of the system. Due consideration is given to the storage constraints and operational constraints of the system. The proposed EMF is used for the LVDC microgrid and tested under the situations of variations in load, variations in irradiance, and storage constraints. The performance of the proposed EMF on the LVDC microgrid is observed to be effective through the simulations on MATLAB/Simulink platform.
