So, you're looking into building homemade DIY wind turbines and saving energy, saving money, and even getting off the grid. There are some great wind turbine DIY books that talk about hand carving blades out of wood and how to make your own generator from scratch. This includes even winding your own coils, welding , etc. This is cheap but not very simple. Not simple at all. I will teach you how to make it simple and cheap.I believe there is too much waste in the world right now. I love the concept of taking something labeled as "junk" and making it new again (upcycling). I hate to see batteries go to scrap when it is easy to get some more life out of them. Imagine all that lead and sulfuric acid has to go somewhere and I'm always afraid it will impact the environment or the water supply.animated windmillI wrote this book for the thrifty person and the "upcycler". Someone who wants to get started into resinential wind power and not break the bank in the process. Someone who hates to see scrap sit around and go to waste. Someone who wants to become independent and off the grid and help the environment. Some people even buy this book so they can refurbish forklift batteries as a business. Imagine getting a free forklift battery that normally costs $4000 new. You recondition it in 30 days and sell it locally for $1500. Some people even take the individual cells out of the forklift batteries to sell seperately. A single cell can cost $400 or more. But you could sell them for $100 each and make huge profits. People need 6 of them, at least, to make 12 volts. And, the best part, you don't even need a truck to do it. I'll show you how to have the batteries dropped off and picked up.This e-book is full of pictures and diagrams to explain the concepts. In it I cover the following and a lot more: * how to make FREE homemade wind turbine blades and it will only take about an hour to finish a set of 3. * a page full of equations and examples of how to use them to figure out power, rpm, tsr, windspeed etc. (units are in miles per hour and feet) * how to find FREE fork lift batteries and how to make them as good as new * making a homemade de-sulfator so you can "pulse" any lead acid or ni-cad battery back into new condition * what kind of generator to look for and how to get the best prices * how to make a simple "furling" system to protect the windmill in high winds * how to charge several banks of batteries all at once while pulsing them back to health * How to make a 1,000 watt wind turbine for less than $150 (including tower) * How to make a 3,000 watt wind turbine for about $220!

Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support.This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor.With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues:modern grid inverter topologies for photovoltaic and wind turbines islanding detection methods for photovoltaic systems synchronization techniques based on second order generalized integrators (SOGI) advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques power control under grid fault conditions, considering both positive and negative sequences Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry. For people from academia interested in adopting the course, a set of slides is available for download from the website. www.wiley.com/go/grid_converters
