An in-depth study of robust MPPT for extend optimal power extraction using wind speed compensation technique of wind generators

To achieve effective power production and control, it is essential to establish an effective maximum power point tracking (MPPT) approach. This makes designing a wind turbine easier. A brand new method called robust changeable step-perturb & observe (RVS-P&O) is created to address the issues of wind speed variable situations, significant oscillations around the maximum power point (MPP), and step size estimate all at once. Where two main points are involved, it is first suggested to choose step sizes systematically based on the normalization of power and speed data. Second, a novel adjustment to compute the power variation is made in order to provide adequate resilience for large and prolonged wind speed fluctuations. According to the simulation findings, the suggested RVS-P&O-based MPPT approach is better to the competing P&O techniques, variable step-P&O, small fixed step-P&O, and large fixed step-P&O. An improvement of 1.34% over the variable step-P&O algorithm is provided by the suggested RVS-P&O approach, which delivers a WECS efficiency of 99.05%, when compared to the 0.032 s, 0.071 s, 0.018 s, 0.012 s, and 0.007 s provided by LS-P&O, SS-P&O, VS-P&O, ME-PO, and AD-P&O, respectively. The settling time for V = 6 m/s is really noticeably improved; it is now 0.004 s. As a result, the RVS-P&O algorithm could be a good choice for MPP online operation monitoring in terms of energy efficiency, transient- and steady-state regime performances under diverse operating situations, and multiple data for wind speed.
