Abstract: This paper has presented comprehensive modeling of direct driven five-phase PMSG based grid-connected wind turbines along with the control schemes of the interfacing converters. Wind speed estimation has been achieved based on measured rotor speed. Five-phase to three-phase interface power converter based back-to-back common dc-link converter has been used to achieve the system objectives. The machine side converter (MSC) is used to track the maximum power point at different wind speed. The grid side converter (GSC) uses a vector current controller to inject pure active power to the grid. The effectiveness of proposed control scheme is validated through extensive simulation results by using MATALB/SIMULINK.

TL;DR: TheVS-PO improves the initial speed tracking and minimizes the steady state oscillations, and the simulation results illustrate the VS-PO superiority over both the conventional P&O (CPO) and modified P &O (MPO) techniques.

TL;DR: Although both proposed algorithms have smallest oscillations, the SA-PO algorithm yields smallest settling time and a 4.34% increase in system efficiency, a fair comparison among proposed algorithms and other current P&O algorithms is deliberated to confirm the SA -PO algorithm superiority.

TL;DR: An efficient and fast adaptive perturb and observe (AD-PO) maximum power point tracking (MPPT) algorithm based on the variable - speed wind energy conversion system (WECS) is proposed to eradicate drawbacks of conventional fixed step-size P&O (CPO) algorithms and to enhance the operation of variable step- size P &O (VS-PO).
