Power Quality Improvement for Grid Connected Wind Energy System using STATCOM-Control Scheme

Abstract

When the wind power is connected to an electric grid affects the power quality. The effects of the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operations. The installation of wind turbine with the grid causes power quality problems are determined by studying this paper. For this Static Compensator (STATCOM) with a battery energy storage system (BESS) at the point of common coupling to mitigate the power quality problems. The grid connected wind energy generation system for power quality improvement by using STATCOM-control scheme is simulated using SIMULINK in power system block set. This relives the main supply source from the reactive power demand of the load and the induction generator in this proposed scheme. The improvement in power quality on the grid has been presented here according to the guidelines specified in IEC-61400 standard (International Electro-technical Commission) provides some norms and measurements.
