- Abstract
Wind energy conversion systems (WECSs) accommodate promising position in global energy market. Due to the dependency of the extracted wind power on various environmental aspects, as wind speed, the relation between the wind power and the turbine speed is highly non‐linear. Hence, maximum power point tracking (MPPT) techniques are mandatory. Conventional perturb and observe MPPT technique suffers well‐known oscillation‐settling time trade‐off. In this study, a state‐flow based wind MPPT technique is proposed offering two degree of freedom, namely dedicated sample time and super‐stepping as WECS is considered to be multi‐rate multi‐input single‐output control system. In addition to being graphically user‐friendly and written‐code‐free, the presented technique offers enhanced operation, minimal oscillations and fast response. Simulations, in addition to experimental results, covering various operating conditions are presented to advocate the effectiveness of the proposed technique.
