TL;DR: In this paper , a smart energy management system is proposed to build a cleaner, greener and sustainable society, which is designed for smart townships having 500 or more independent luxury villas which span across at least 100 acres or more.
Abstract: The advent of on-site and decentralized power generation poses a major challenge to conventional power grids in the form of virtual storage requirement. This has led to a trend of developing systems that rely less on the grid and behave more as a standalone generation source. The proposed energy management solution influences the on-site generation and facilitates demand response by shifting the flexible loads based on forecasted data. To ensure that self-utilization of energy is efficient within the district or community, an agent-based control model is modelled. This project is designed for smart townships having 500 or more independent luxury villas which span across at least 100 acres or more. Once the individual villa's power demands are met, then with the help of a robust interconnected micro-grid across the entire township the rest of the power demands are met. As the load demand and renewable are uncertain throughout the day, an energy management system is essential to ensure grid stability and achieve reductions in operation costs and carbon dioxide emissions. A smart Energy Management System is proposed in this paper to build a cleaner, greener and sustainable society. A conceptual scaled down model of the smart townships employing mathematical models/equations and implementation of the same by Simulink tool in MATLAB is proposed in this paper.

TL;DR: In this paper , the speed control of a three-phase induction motor in response to temperature fluctuations has been investigated in the context of real-time cement manufacturing application, where the cooling system is used to control the speed of the induction motor.
Abstract: The induction motor is the device that is used to convert three-phase alternating current into mechanical power. Induction motors, on the other hand, do not operate at synchronous speed; rather, they are primarily fixed-speed motors. In industrial settings, it is necessary to run Induction Motors at the proper speed, which varies depending on the application. As a result, there is a growing need for techniques of speed control for induction motors. There are many different ways to regulate the speed of an induction motor. This work aims to manage the speed of a three-phase induction motor in response to temperature fluctuations. Residential and industrial environments utilise induction motors extensively. This is automated the coolers in the Cooling sector for a real-time cement manufacturing application. PLC and VFD control speed. Induction motors operate at a steady speed, not synchronously. According to the applications, It operate the induction motors in industries at the necessary speed.

TL;DR: In this article , a case study for the electric vehicles inverters was conducted to simulate the model of a larger battery for an existing electric vehicle to turn it into a series hybrid vehicle, and the main goal was to keep the SOC of the rechargeable battery within a range that the user has already set.
Abstract: This work deal with modeling and simulation based case study for the electric vehicles inverters. Several type of the the inverters have been investigated in this study. Inverters are playing a key role in the fie4ld of electric vehicle applications. Due to the widespread use of vehicles that run on fossil fuels, the transportation sector is a big cause of climate change but also health problems. Countries around the world are trying to switch from vehicles that run on fossil fuels to electric cars (EVs) to cut down on pollution. EVs do have some practical problems, though. One is ”range anxiety,” which is caused by the lack of charging stations, the high cost of looooong EVs, and the short range of affordably priced EVs. One possible solution to the problem of range anxiety is to use range extenders [4], which allow EVs to drive farther while keeping costs and performance as low as possible. Through a range extender, this paper will try to simulate the model of a larger battery for an existing electric vehicle to turn it into a series hybrid vehicle. The main goal of the project is to keep the SOC of the rechargeable battery within a range that the user has already set. The advantages provided by the range extender are in terms of safety and comfort. The use of range extender if properly implemented in affordable EVs Fig. 1. Inverter classifications in published literature has the potential to make the vision of mass market EVs a reality.

TL;DR: In this article , the authors present a wireless power transfer mechanism for electric cars (EVs) that is efficient, tolerant of misalignment, and compact, based on a traffic numerical solution based on mesoscopic techniques.
Abstract: This research paper presents a wireless power transfer mechanism for electric cars (EVs) that is efficient, tolerant of misalignment, and compact. To accurately estimate the amount of electricity required from an energy provider for charging, a traffic numerical solution based on mesoscopic techniques is used to simulate freight distribution. Cooperative driver assistance systems (ADAS) are employed to manage lane changes and vehicle positioning. The study shows that traffic has a significant impact on the energy system, with high traffic levels and slower median speeds increasing the total output required by over 50% compared to low traffic scenarios. The paper provides valuable insights into the energy requirements of wireless EV charging in real-world traffic scenarios.

TL;DR: In this article , a 13 level symmetric multi-level inverters, having a reduced number of switches by using particle swarm optimization technique, capacitors, diodes, are compared with other topologies and are simulated using MATLAB.
Abstract: Power electronic inverters are gaining extensive attention in various industrial drive applications. Incorporating renewable energy sources with energy storage devices with efficient power electronic converters overcomes the major difficulties associated with carbon foot prints. Multi-level inverters are designed to achieve high power ratings, with reduced number of switches. Many of the researchers are focusing on issues that can minimize harmonics in order to obtain higher voltage levels. In this paper 13 level symmetric multi-level inverters, having a reduced number of switches by using particle swarm optimization technique, capacitors, diodes, are compared with other topologies and are simulated using MATLAB. Microcontroller is used to develop the required gating pulses for the inverter switches. The prototype hardware is developed which generates 13 level output voltage and the effectiveness was demonstrated using harmonic analysis with THD of 3.36%.

TL;DR: In this article , an operation of a three-phase distributed energy source based isolated microgrid is presented, where solar photovoltaic (PVV) is considered the primary energy source.
Abstract: An operation of a three-phase distributed energy source based isolated microgrid is presented in this work. Here solar photovoltaic (PV) is considered the primary energy source. A battery energy storage (BES) is used as an energy storage unit to improve the inertia of the system. The operation of the microgrid is studied during varying solar insolation and load unbalancing. The voltage source converter (VSC) attached to the BES maintains the voltage and frequency at the point of common coupling (PCC). It also supplies the non-fundamental apparent power demand of the load. The VSCs connected to the PV module inject the total active power generated to the PCC. The net fundamental reactive power demand of the load is shared equally between the VSCs.
