Now that the population is growing, the expenditure on basic needs of life is also increasing due to a lack of or less availability of resources. The economy consumed electricity is reaching peaks as its main fuel, coal, is decreasing day by day. Due to this, 90% of the population who are in the middle class, lower middle class, or rural areas are economically poor and are unable to bear the prices. To overcome the financial problems, many researchers have prepared various types of microgrids that generate electricity from various types of flow resources, like hydro, solar, biogas, and air current power stations, whose system is called a compound flow power system. This paper gives a combined review of various research papers that discuss some case studies and some research on various models designed on software like HOMER Pro, how microgrids become economic barriers, optimal power supply solutions with CFPS, distributed and centralized microgrid components, the technical and economic feasibility of EV charging stations, and the analysis of various combinations of power systems at various locations like Bangladesh, Canada, the Republic of Djibouti, China, Indonesia, Sierra Leone, some rural sites in India, and some developing countries. This overview provides a glimpse into the various aspects of CFPS, including fusion approaches, techno-economic analysis, simulation platforms, storage technologies, design specifications, unit sizing methodologies, and control techniques. Further research and analysis in these areas are needed to explore their applications and advancements in CFPS development. The main reason for the study is to analyze and bring various ideas and models of various researchers together on a common platform and make a combined conceptual framework for further proceedings. © 2023, The Author(s).

Scalable Computing 2025年第2期26卷 587-598页

作者： RAMANI, R. NALINI, A. Department of Electrical and Electronics Engineering M.G.R. Educational and Research Institute Tamilnadu India

In the arena of renewable energy integration for electric vehicle (EV) infrastructure, it is a problem to efficiently use solar power with EV charging, considering grid constraints and user preferences. The current study proposes a new smart charging algorithm that utilizes IoT data for the dynamic optimization of EV charging patterns. A novel aspect of the study was a deep learning model, "EVGridNet", that reliably predicts solar energy output and grid prices. EVGridNet uses deep learning approaches to process accumulated data via IoT devices, facilitating fine-tuned adjustments to charging patterns through predictive analytics. This algorithm receives actual data on the generation of solar energy, the price of grid electricity, and other characteristics set by the user to optimize the usage of solar energy, limit the usage of grid electricity during the peak hours and meet all the needs of the user. The optimization process of the algorithm strategically manages energy sources, uses battery storage systems to exploit solar power effectively and uses grid electricity during low-cost periods, all within user preference parameters. The proposed system has the potential of reducing grid electric use by up to 25% for EV charging, and increasing the renewable energy electricity in EV charging to 40% as per simulation results. This will enable quick EV infrastructure scalability, low carbon emission, and energy independence. EVGridNet is an outstanding innovation in smart charging technology, which is a cost-effective and scalable solution to the renewable energy sector's primary challenge. One of the key aspects of the optimization process is the control of energy sources where battery storage systems allow for flexibility in using solar energy and grid electricity within certain pre-set thresholds. © (2025), (West University of Timisoara).

作者： Namboothiri, Kannan Madhavan Sundareswaran, K. Nayak, P. Srinivasa Rao Simon, Sishaj P. Department of Electrical and Electronics Engineering National Institute of Technology Tamil Nadu Tiruchirappalli620015 India

This research proposes a data-driven method for estimating the state of charge of lithium-ion batteries using two neural networks, namely long short-term memory (LSTM) and bidirectional LSTM. The two schemes are computationally evaluated for various temperatures, changing the quantum of input samples, with different training and testing datasets, with additional chemistry battery, and introducing a dropout layer. Statistical error indices, namely RMSE and MAE, are calculated for three training optimization algorithms, namely SGDM, RMSProp, and ADAM. These results show the potential of the NNs in estimating the SoC. The accuracy is also compared with existing well-established data-driven methods employing DNN, CNN-GRU, and GRU NNs. It is observed that the proposed NNs have simple topologies and that the SoC estimate findings are reasonably accurate. © 2023, The Institution of Engineers (India).

The current era has seen an enormous rise in contamination of the environment, resource expense increases, petroleum depletion, and higher consumer demands, all of which have contributed to the rapid expansion of Electric Vehicles (EVs). Furthermore, because conventional burning engine-powered cars create significant levels of pollutants, there is a growing demand for EVs powered by renewable energy sources (RES). PV-powered EVs are especially important because they are accessible every day and are simple to install. However, because PV systems are irregular, voltage variations occur. As a result, increasing the result of the PV organization is required. An improved DC to DC SEPIC converter is employed in this work to improve PV output, which is then used in submissions involving electric vehicles. To keep the link voltage of the DC at the output of the DC-DC converter consistent, a Grey Wolf Optimization (GWO) founded continuous loop approach is used. The electricity generated by the output of the Single ended primary inductance converter (SEPIC) is then supplied to Voltage source inverter (VSI), where it is transformed into AC power and served to EV or grid. The PI controller is used to achieve grid alignment. The recommended method reduces THD, lowers switched losses, and helps enable better energy control at EVs, resulting in uninterruptible power supply. In addition, it is executed in MATLAB/Simulink to test the performance of the recommended task. © 2024 IEEE.

The demand for renewable energy sources (RES) is expanding these days and solar energy are the primary energy sources found in the world. It is a healthy substitute for fossil fuels. As a result, it is now essential to apply power electronics in the solar power producing zone. The main technique for producing such renewable resources fast and efficiently is the use of converters and inverter. In this study, a Zeta converter (shows 94.7 % efficiency) with a modified ANFIS logic controller (shows 95% accuracy) is used to feed photovoltaic (PV) energy sources to load needs. One of the key benefits of the Zeta converter is its ability to maintain consistent input and output currents. It lowers the electromagnetic interference, lower input and output current ripple, and improved dependability. In the event of a changeable load, the modified ANFIS controller for the SEPIC converter, which served as the connection among the power source and the inverter, maintains a constant voltage and displays a little continuous error as well as a minor overflow. MATLAB/Simulink is used to verify the development and evaluation of a Zeta converter based on PVs. © 2024 IEEE.

William, Blanie Scrimshaw Department of Electronics and Communication Engineering Francis Xavier Engineering College Tamilnadu Tirunelveli627003 India Department of Electrical and Electronics Engineering Sri Krishna College of Technology Tamilnadu Coimbatore641042 India Department of Electronics and Communication Engineering Karpagam Academy of Higher Education Tamilnadu Coimbatore641021 India Department of Electronics and Communication Engineering SEA College of Engineering and Technology Karnataka Bengaluru560049 India Department of Electronics and Communication Engineering KPR Institute of Engineering and Technology Tamilnadu Coimbatore641407 India Department of Computer Science and Engineering Rohini College of Engineering and Technology Tamilnadu Kanyakumari629401 India

The ternary logic has a benefit over the binary logic which provides a secured solution to achieve a trade-off between the area and power of the design. However, from the structure of the ternary Aritmetic Logic Unit (ALU), it is clear that its architecture increases the area, propagation delay, and power consumption. To overcome this drawback, a loopback algorithm is proposed to achieve low power and high throughput Internet of Things (IoT) processors. The loopback algorithm reduces the number of processing stages in multipliers and adders which can significantly reduce area and power dissipation. The proposed 2:1 multiplexer-based approach reduces the need for a decoder and results in low power consumption. The proposed design will be implemented in Xilinx ISE 13.0 and simulation will be done in Modelsim. The modified Ternary ALU (TALU) performs finer than the previous TALU method. The number of registers used in this architecture is reduced by up to 25% than the existing system therefore there is a reduction in power dissipation. © (2024), (International Hellenic University - School of Science).
