Hydroelectric generation uses the kinetic energy of flowing water to generate electricity. Water spins a turbine connected to a generator, which contains a rotor with magnets that spins inside a stator with coils of wire, inducing electricity in the coils. Most hydroelectric stations use dams to raise water levels and increase the force of falling water to spin the turbine. The generator converts this rotational energy into electrical energy that can power homes and businesses. Building a small-scale hydroelectric generator requires a turbine, generator parts like a rotor and stator, and a water source to drive the turbine. Hydroelectric power has advantages of being renewable, producing no pollution, and being very reliable.

Coin based mobile charging using solar tracking system
Now a days students and many other people use the public transportation , people who are making very long journey in order attend business conventions, conferences, or for any private purpose don’t know that their battery level is low and they often forget their charger at home or in hotel rooms. In rural areas there is no continuous power supply about 13-14 hours. Many times battery becomes flat in the middle of conversation particularly at inconvenient times when access to a standard charger isn't possible . Many critics argued that long distance traveling vehicles provides power points. Even though one or two power points are provided at a particular place in the vehicles it is not all sufficient for all the passengers, therefore need to provide a public charging service is essential and coin-based mobile battery chargers are designed to solve these problems

Multilevel inverter
This document discusses a multilevel inverter project for drive applications. Multilevel inverters can operate at higher voltages and produce lower harmonic components. The project involves simulating a 3-phase 3-level cascaded H-bridge inverter in MATLAB Simulink. A DSP processor is used to generate switching signals, which are then sent to a gate driver circuit to drive the inverter. Hardware implementation of a 3-level inverter gate driver is presented, along with gate drive pulses and dead band generation. Future work includes implementing a 3-phase 3-level inverter for motor speed control and comparing THD of sine and space vector modulation.
cascaded multilevel inverter project
The document presents a new topology for a submultilevel inverter and proposes connecting multiple submultilevel inverters in series to create a generalized multilevel inverter. The proposed multilevel inverter uses fewer switching devices than existing topologies and is analyzed under symmetric and asymmetric conditions. Simulation results using MATLAB-SIMULINK show the asymmetric 31-level inverter has distortion of only 0.2% using 12 switches, while the symmetric 13-level inverter has 0.8% distortion using 16 switches.

About Solar Inverter
A solar inverter, or PV inverter, converts the direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network.
Mulilevl inverter
This document summarizes different types of multilevel inverters. It begins by defining an inverter as an electrical circuit that converts DC power to AC power while regulating voltage, current, and frequency. It then classifies inverters based on their source, configuration, output waveform, switching devices used, and methods of inversion. Specific types of inverters discussed include a single-phase half-bridge inverter, which uses two SCRs, two diodes, and a three-wire supply to produce an alternating output voltage. The document also includes diagrams illustrating the operation and output waveform of a single-phase half-bridge inverter.
Presentation 12v dc to 230v ac 100 wat invertor
This document presents the design of a 100 Watt inverter by a group consisting of M. Sohail, M.Usman, and Ahmad Ali. The inverter uses a 12V battery to power an IC and two MOSFETs that convert DC to AC through switching. A step-up transformer increases the output voltage to 230V AC.

Hybrid inverter project report
The need of running AC Loads on solar energy leads us to the design of Solar Power Inverter.. Since the majority of modern conveniences all run on 220 volts AC, the Power Inverter will be the heart of the Solar Energy System. It not only converts the low voltage 12 volts DC to the 220 volts AC that runs most appliances, but also can charge the batteries if connected to the utility grid as in the case of a totally independent stand-alone solar power system. These are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger.
An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
