Grid Power Smoothing Management for Direct-Drive PMSG Variable-Speed Wind Energy Conversion System with Multilevel Converter

Abstract

It uses a boost converter configuration, a multilevel converter, and a PI controller for a turbine related to the permanent magnet synchronous generator (PMSG) for coordinated network operation. In wind turbine generators, voltage and frequency are variable due to erratic wind flow. An inverter, a rectifier, and a boost converter are all part of a power converter. Here, we present a simple AC/DC conversion of a PM synchronous machine (PMSM) with maximum power point tracking (MPPT). The proposed topology makes use of five level of multilevel converters to transform the three-phase AC voltage generated by the PMSG into a set of DC hyperlink voltage. During this PI controller, variations within the obligation ratio and ceaselessly various output voltage are used to take care of the DC hyperlink voltage at fixed ranges. A multilevel converter offers direct power angle management attributable to its voltage-controlled rectifier. In this paper, we present a control technique for wind power conversion programs with no different energy storage units (ESS), which depends on the wind turbines’ management to easy the output power. Matlab/Simulink is used to create the model of the direct-drive PMSG-based wind power generation, together with simulation outcomes to validate the effectiveness of the power smoothing algorithm. The experiment within the laboratory shall be continued in future analysis.
