Variable step learning based control algorithm for power quality in PMSG based power generation system

In this article, Power generation system model includes a turbine model of wind system, PMSG model, and a Simulink model of drive train. The generated power through the wind power plant is fed to three phase linear and non-linear load. The power electronics based shunt connected custom power devices are used to suppress the power quality problems at constant speed turbine. The objective of this paper is to compensate harmonic and reactive power due to non-linearity of loads and maintained rated voltage at the point of common interface (PCI). This shunt connected compensator as a DSTATCOM is controlled through variable step learning based adaptive control algorithm. The simulation waveforms show the satisfactory performance of PMSG System and the control algorithm.
