Verification of MPPT for a wind power system by hysteresis and vector controllers using DC-DC super lift boost converter

This article discusses a modified maximum power point tracking (MPPT)-based super lift Luo DC-DC converter and compares it with a traditional boost converter for a grid-connected wind energy system under variable speed conditions. A three-bladed fixed-pitch turbine, a permanent magnet synchronous generator (PMSG), a three-phase unregulated rectifier, a DC-DC converter, a PWM inverter, and a modified MPPT compose the overall system. In dq–synchronous reference frame theory, the PMSG is modelled. A combination of an unregulated rectifier and a super lift Luo DC-DC converter is utilized to extract the most power from the generator. The PWM inverter converts the boost converter’s dc output voltage to ac voltage. The grid side converter uses two control methodologies for grid voltage regulation: hysteresis current control and field-oriented control based on the proportional-integral (PI). The grid side controller changes the modulation index of the PWM inverter to maintain a constant grid voltage. In contrast, the generator side controller maintains an optimal tip speed ratio to ensure that the system operates at maximum power. Finally, detailed simulation results are employed in the MATLAB/SIMULINK environment to validate the efficiency of the suggested solution. The findings demonstrate that the positive super lift converter has an outstanding boost converter in fast reach to steady-state and small ripple up to 0.63% for output load current and 0.55% for load voltage.
