The purpose of this volume is to explain more specifically how rural electrification could be most effectively used to help the numerous and disadvantaged rural masses of the third world move away from their subsistence type of existence. and significantly improve their quality of life in the coming decades. Electric power is a vital engine for growth. not only in. This book was written while the author was living and working in Sri Lanka. An attempt is made here to provide a comprehensive and balanced treatment of rural electrification and associated topics. in the context of development.

This book deals with several selected aspects of electric power quality issues typically faced during grid integration processes of contemporary renewable energy sources. In subsequent chapters of this book the reader will be familiarized with the issues related to voltage and current harmonics and inter-harmonics generation and elimination, harmonic emission of switch-mode rectifiers, reactive power flow control in power system with non-linear loads, modeling and simulation of power quality issues in power grid, advanced algorithms used for estimating harmonic components, and new methods of measurement and analysis of real time accessible power quality related data.

Power distribution and quality remain the key challenges facing the electrical utilities industry. Technology alone cannot provide a solution to power quality problems, and there exists a variety of procedures and programs that can be put in place to ensure reliable, high quality electricity. With chapters carefully culled from the best-selling Electric Power Distribution Handbook, Distribution Reliability and Power Quality provides an economical, sharply focused reference for engineers and technicians working in this specialty area of power distribution. The book introduces the concept of reliability, outlining various methods of assessing and improving reliability along with the factors that affect it. It follows with a detailed look at voltage sags and momentary interruptions, various solutions to these issues, power quality monitoring, and other quality issues such as voltage unbalance and harmonics. Because faults are the cause of many interruptions and other power quality problems, the author devotes a detailed chapter to various aspects of faults. Focused on enhancing the delivery of high-quality power, this volume includes a new chapter on reliability and power quality improvement programs that provide a roadmap to better performance and ultimately to higher efficiency. Presenting a host of practical solutions for reliability and power quality specialists, Distribution Reliability and Power Quality gathers critical tools, techniques, and knowledge into a single source that is ideally suited for immediate implementation.

The solar Photovoltaic (PV) technology is gaining significant levels and is going to contribute a major share of total generated electricity in the coming years. PV technology is becoming a promising alternative source for fossil fuels. However, Power Quality (PQ) is the major concern that occurs between the grid and an end user. Any typical electrical distribution system exhibits a passive characteristic with respect to power flows when power flows from a substation to load. However, with inclusion of solar PV generators, this behaviour tends to be changed. The main characteristics related to PQ, such as voltage level, frequency, power factor and Total Harmonic Distortion (THD), may be affected. This book presents the analysis of PQ with the integration of grid-connected PV systems as distributed generation. The role of Maximum Power Point Tracking (MPPT) technique is investigated through implementing few basic MPPT techniques. Using the Matlab-simulation platform, the analysis of PQ is demonstrated. This analysis is based on real measurements of THD, Voltage levels, Current levels, DC voltage levels, real power and reactive power flows.
