The increasing complexity of today's power systems, and the growing numbers of power electronic devices that are being introduced, adds to the risk of power quality problems caused by harmonics. Non-linear loads into power systems, non-sinusoidal and distorted current waveforms, and voltage distortion have become more common, and these phenomena can lead to power losses and damage to equipment. Understanding and Managing Power Quality Issues is a reference for researchers involved with power systems, professionals in power equipment industry and at grid operators, as well as for advanced students, transmission network and grid operators. The authors use mathematical analysis to describe the mechanisms of various power quality issues. Harmonics in the power system are a major focus, and coverage also encompasses power quality of power supply systems, reliability indices, sinusoidal and non-sinusoidal conditions, techniques for control of voltage variation, reactive power, active power quality management, and current trends.

Renewable energy alternatives are fast becoming viable options to battle conventional fossil fuel shortcomings such as pollution, cost, and limited reserves. Understanding the requirements and source characteristics for successful power electronics and their application is pivotal to extracting power successfully. Power Converters for Extraction and Conversion of Solar Photovoltaic Energy provides a detailed analysis of the various power converter operations fed by solar PV energies. Practical aspects addressing the behavior of systems such as the operating point on source characteristics and when power converters buck or boost are considered as well, and are fundamental to effective use and applications of renewables. With computer simulation models for typical systems to give the reader a deeper insight and “feel” for the actual system, this book provides readers with a useable tool to develop and design their own systems and achieve successful power extraction.
