Design and state of art of innovative wind turbine systems

Wind energy using increased dramatically in the last years. Because of that wind turbine design should be improved to increase efficiency. To make wind turbine with the best characteristics and with the highest efficiency it is suitable to analyze factors that are truly relevant to the converted wind energy. Wind turbine innovative design is investigated in this paper by the theory of inventive problem solution (TRIZ) as a systematic methodology for innovation. TRIZ methodology should provide creative conceptual design ideas of wind turbine. The main aim of this work is to show a systematic methodology for innovation as an effective procedure to enhance the capability of developing innovative products and to overcome the main design problems. The TRIZ method will be used in order to eliminate the technical contradictions which appear in the wind turbine systems. (C) 2016 Elsevier Ltd. All rights reserved.
