Power Quality Improvement in Grid Connected Wind Energy System

Abstract

The wind energy generation, utilization and its grid penetration in electrical grid are increasingworldwide. The wind generated power is always fluctuating due to its time varying nature and causingstability problems. This weak interconnection of wind generating source in the electrical network affects thepower quality and reliability. The influence of the wind turbine in the grid system concerning the powerquality measurements are the active power, reactive power, variation of voltage, flicker, harmonics, andelectrical behavior of switching operation and these are measured according to national internationalguidelines. The paper obviously demonstrates the presence of power quality issue because of establishment of wind turbine with the grid. In this STATCOM is utilized with energy storage system (BESS) to decrease the power quality issues. The STATCOM control scheme for the matrix associated wind vitality era framework to enhance the power quality is simulated utilizing MATLAB/SIMULINK in power system block set.
