Dynamic wind estimation based control for small wind turbines

Synergies of Wind Turbine control techniques

“…Other concerns are the cost efficiency needed to overcome inputs [14] and record efficiency as expected [4,15,16]. The major challenge though remains to be the energy generation prediction and control techniques [16][17][18][19][20][21][22]. These challenges and concerns makes these systems more expensive than LSWT and therefore individualised in their urban application site due to different and uneven manner of the flow patterns and adaptation [23][24][25][26].…”

“…The rotor angular speed measurements give the dynamic estimates for these higher and lower ratios to analyse the stability of the closed loop performance of the WT and the dynamic power conditions in wind fluctuations [19]. For the stability estimation the nonlinear control is attributed to this ratio regulation to enable maximum power for the fixed pitch variable wind speed WT [20].…”

“…One of the most common problems that face researchers when dealing with wind system is the difficulty of obtaining a direct measurement of wind speed due to wind speed variations at different points over the blades swept area [10,11]. Mechanical sensors can be used to overcome this obstacle, but this will increase the cost of both equipment and maintenance [12]. An alternative solution is to analyze the wind speed effectiveness through utilizing indirect methods, which requires studying other signals such as electric torque, output power and generator rotor speed [13][14][15][16].…”
