Abstract
To harvest the maximum power from an offshore wind energy-conversion-system (ECS), a robust controller is required to run the ECS constantly at the maximum-power-point (MPP). The maximum power point tracking schemes are developed via PID (proportional integral derivative) control, a model based SMC (sliding mode control) and a model based STA (super-twisting algorithm) to achieve supreme power from a permanent-magnet-synchronous- generator (PMSG) based variable speed wind energy conversion system (VSWECS). A detailed comparative analysis is carried out among the three competitors in MATLAB Simulink environment for a random wind energy speed profile. Furthermore, the final simulated results are analyzed and compared with results from standard feedback linearization (FBL).
