Design and Construction of a 0.75KVA Inverter Power Supply for Nigerian Homes...ijtsrd
Over the years, there have been a gradual increase in the electricity generation capacity of Nigeria, with more gas power plants installed between 1999 2003 to augment power supply from the existing hydro and thermal power plants installed in the 1970s but despite gradual increase in Mega Watts MW of electric power generated, Nigerian electricity consumers continue to experience epileptic and unreliable power supply distribution. As at today, the power distribution companies referred to as the DISCOs supply epileptic or skeletal power to their customers which they termed 'load shading’. This term explains a situation whereby a power consumer or customer can obtain a power ration for some hours in the day and do not have power remaining hours in the day. Because of this, many consumers depend on generating sets as alternative source of power. This is inefficient and costly to maintain. Today it is possible to introduce the electric power inverter which converts battery DC voltage to AC voltage. Inside the inverter can be coupled an electric charging system which can charge the battery when there is power supply from utility power source. When this power source fails, the battery in turn supplies the inverter with DC which is being converted to A.C sometimes the inverter can also be connected to renewable energy source like solar, wind etc. These sources ensures an all round supply of DC for the inverter. Renewable energy can be particularly suitable for developing countries such as Nigeria where public power supply is totally unreliable. In response to the yearning of the majority of Nigerians for a steady power supply, this research paper tries to contribute in a little way by designing and constructing a 0.75KVA inverter to power homes and offices. The paper starts by defining what an inverter is, reviewed similar past works in literature, and it explained the principles of operation and components used with its circuit diagram. The completed work was tested and met its design specifications. Lois O. Nwobodo | Nkemdilim Ifeyinwa Obiokafor | Samuel C. Asogwa | Fidelis C.

It covers topics such as renewable energy sources, smart grid domains, global energy statistics, objectives and advantages of integrating renewables, HVDC transmission, devices used, and communication and security considerations. The key points are that renewable sources can be integrated efficiently using HVDC transmission and power electronics, smart grids allow for better control and monitoring across generation, transmission and distribution domains, and communication standards are important for interoperability.
Renewable Energy Sources are being used in Off-Grid mode. By integrating all these sources to a common point energy efficiency can be improved and frequent dynamic faults can be avoided. This approach needs to implement smart grid and technologies.
FORMULATION AND EXECUTION OF A DC TO DC BOOST CONVERTER WITH NON-CONVENTIONAL...IRJET Journal
1) The document discusses the formulation and execution of a DC to DC boost converter to increase the voltage from a non-conventional energy source for powering an electrolyzer.
2) A boost converter using IGBT switches is designed and simulated in MATLAB to increase the voltage from 32.69V from a 200W solar panel to 226.5V required by the electrolyzer.
3) The simulation results show the converter can achieve over 92% efficiency at full load and maintain the output voltage between 180-226V with varying input voltage and load, making it suitable for powering the electrolyzer from a solar energy source.
A Noval Method for Improving Power Quality of the Distribution System Connect...IRJET Journal
This document presents a novel method for improving power quality in a distribution system connected to a microgrid using a flexible AC distribution system device. The device aims to compensate for harmonics, regulate voltage and frequency variations, and provide real and reactive power support during islanding operations of the microgrid. The control design employs a new model predictive control algorithm that separates the steady-state and transient control problems, reducing computational time. Detailed simulations in MATLAB are presented to demonstrate the capability of the proposed device to maintain high power quality in the distribution system and microgrid.
Hydropower plants convert the kinetic energy of flowing water into electrical energy. Water is directed through turbines that spin generators to produce electricity. There are various types of hydropower plants classified by the height of the dam and head of water, including low-head, medium-head, and high-head facilities. Hydropower is a renewable energy source that provides power through the continuous water cycle, but construction can be costly and disruptive to local ecosystems.
The document describes an automated dam monitoring system that uses sensors and data acquisition to measure key parameters like water velocity, pressure, level, and vibrations. It channels water for irrigation and power generation. Sensors measure these parameters and feed data to a control system built in LabVIEW. This allows remote monitoring and control of dam operations to ensure safety and optimize water usage.
HYBRID POWER GENERATION SYSTEM From KMP CollegeHIGHVOLTEEE
Today, the world is progressing at quite a fast rate with the use of the conventional sources of energy. The two major demerits of using them are the environmental pollution created by its use and its limited quantity.
On the other hand the Non-conventional sources of energy are available in plenty, free of cost and pollution free.
Many types of clean and renewable energy sources can be used in the production of electrical energy.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
