Multi Level Inverter Based STATCOM for Grid Connected Wind Energy Conversion System

Gundala Munireddy


The  sustainable energy resources, like  wind  energy, for electrical energy  generation is augmented  due  to environmental  problems  and  the  scarcity of  conventional  energy  sources, leading to integration of large number of wind generators in to grid. Integration of large scale of wind generators in to grid presents challenges such as voltage stability, reactive power management, frequency control, grid stability and power quality. In this proposed scheme, Multi Level Inverter based Static Compensator with a battery energy storage system employs Hysteresis Current Controller to diminish the effects of power quality issues. The proposed scheme for the grid connected wind energy conversion system is simulated using MATLAB/SIMULINK. The efficacy of the proposed control scheme is, it takes care of the reactive power requirement of the load and the induction generator, thus improving the source side power factor and also there will be a discernible reduction in the Total Harmonic Distortion. Using Multi Level inverter based STATCOM, lower source current distortions and lower switching frequency shall be obtained, when compared to conventional two level inverter based STATCOM.
