Generally, artificial neural network‐based MPPT algorithms use basic neural network architectures and inputs which do not represent the ambient conditions in a comprehensive manner. In this article, the ambient conditions of a location are represented through a comprehensive set of environmental features. Furthermore, the inclusion of time‐based features in the input data is considered to model cyclic patterns temporally within the atmospheric conditions leading to robust modeling of the MPPT algorithm. A transformer‐based deep learning architecture is trained as a time series prediction model using multidimensional time series input features. The model is trained on a dataset containing typical meteorological‐year data points of ambient weather conditions from 50 locations. The attention mechanism in the tran...

Many Indian cities are grappling with air pollution, majority of which is the result of increasing number of vehicles on roads. To contain the rising pollution, countries all over the world are working on alternative sources of energy to meet their energy demand. India out of all countries is in dire need of an intervention to reduce air pollution. Electric vehicles offer a clean alternative mobility solution and can be relatively easily introduced in the two and three wheeler market in India. The present study discusses the need for electric vehicles in India and the technologies available in the market which can be implemented in the Indian scenario. The paper also discusses about the policy decisions taken by the government and investments made by Indian automotive makers in electric vehicle segment. Finally, the paper highlights some of the barriers which are preventing or slowing the growth of electric vehicles in India.

As the distributed energy generation and storage are gaining momentum it Is required to have ESS that can regulate the power bi-directionally, presently the ESS are bulky in size, to enhance the power density and converter efficiency, an integrated transformer is introduced and simulated using 3D Finite Element Analysis (FEA). Essentially, a simple PI-based voltage/current control loop Is implemented on a 32-bit microcontroller (TMS320F28379D). Also, synchronous rectification (SR) Is implemented by controlling the turn-on and turn-off delays on rectifier sides, respectively. The design and control of the CLLC converter are verified through the experimental results. A 300 kHz, 700 W prototype Is built with the peak conversion efficiency of 96.6% while charging and 96.4% while discharging

The parameters considered here are the net area covered by the PV modules and the net area swept by the revolving blades of the wind turbine. The objective of this scheme is minimization of life cycle cost (LCC) of the HES and to ensure its reliability at the same time. Loss of power supply probability (LPSP) is the factor considered to measure the reliability of the proposed system. This paper discusses a fitness function which can be used for the combined optimization of the two objectives. The proposed model uses genetic algorithm (GA) to obtain the best suiting values of the decision variables.
