This book covers electric energy from alternative energy sources including solar, wind, hydro, biomass, geothermal, and ocean energy. Core issues discussed include wind and solar resource estimates, characteristics of direct conversion, renewable energy analysis, electromechanical conversion, and storage devices used in alternative energy systems. Power system and smart grid issues associated with integration of renewable energy sources into the electric grid are explored in detail. Readers are encouraged to write their own solutions using the included MATLAB® scripts.
