Abstract
The Renewable energy sources, which have been expected to be a promising alternative energy source, can bring new challenges when it is connected to the power grid. On the basis of measurements and norms followed according to the guidelines specified in IEC-61400 (International Electro-technical Commission) standard, the performance of the wind turbine, power quality is determined. The power arising out of the wind turbine when it connected to grid system concerning the power quality measurements are-the active power, reactive power, voltage sag, voltage swell, ?icker, harmonics, and electrical behaviour of switching operation and these are measured according to national/international guidelines. The paper clearly shows the existence of power quality problem due to installation of wind turbine with the grid. In this proposed scheme a FACTS device (STATCOM)} is connected at a point of common coupling with a battery energy storage system (BESS) to reduce the power quality problems. The FACTS Device (STATCOM) control scheme for the grid connected wind energy generation system to improve the power quality is simulated using MATLAB/SIMULINK in power system block set. The intended result of the proposed scheme relives the main supply source from the reactive power demand of the load and the induction generator.
