Control policies for wind-energy conversion systems

摘要: Wind energy is usually converted into electrical through a wind rotor driving generator. It well known that maximum conversion efficiency occurs when the loaded in such way its rotational speed allowed to fluctuate sympathy with wind-speed variations. In paper, wind-rotor/generator dynamics are investigated for number of control policies, and it shown system response function speed. Owing this relationship, strategies based on static optimum matching premises unlikely be optimal under continuously changing conditions. To prove hypothesis, aerogenerator were simulated an analogue computer, and, given recorded windspeed sample, delivered was measured strategies. The results indicate that, sample used simulated, sophisticated policies do not necessarily result yield. An attempt made interpret paradox terms
