Global warming is considered to be one of the most critical problems that the environment will be faced with in the next fifty years. The use of Renewable Energy Sources (RES) for the production of electrical power can contribute significantly to the reduction of greenhouse emissions, such as carbon dioxide and other harmful emissions (NOx, SOx) usually found in fossil fuel combustion exhaust. This book provides a comprehensive approach for the design, optimisation and control of integrated RES stand-alone power systems.
