MPPT Control of a Variable-Speed Wind Turbine

Abstract

This paper deals with the control of a variable speed permanent magnet synchronous generator (PMSG) for a wind stand-alone system. In order to maximize the generated power, PMSG is controlled by a maximum power point tracking (MPPT) control and a maximum efficiency control. The studied system consists of a permanent magnet generator, buck-boost converter, transformer, inverter, AC load, and battery bank (to store a surplus of wind energy and to supply power during a wind power shortage). Simulation results show the effectiveness of the proposed control method.
