The extraction of wind energy should be conducted especially for decline condition in wind power in order to intensify electrical power production. This paper introduced the use of supervisory control scheme which consists of a regulatory control level and a supervisory level. The first level has a function to keep the wind turbine system produces maximum power in safety manner using two PI controllers which track any reference rotor speed. The latter level is used to adjust the speed setpoint to its optimum value. Here the dynamic optimisation problem is solved by using the extremum seeking algorithm which is then compared with using the reference formula. The proposed method was applied in simulation to a small scale horizontal axis wind turbine operating in region II of wind speed condition.
