Enhancement of Power Quality through Shunt Compensators and Main Grid Interfaced with DGs

Injection of power generated by the wind turbine system into an electric grid mainly effects the power quality. The performance of this wind turbine and its power quality is determined on the basis of its measurement of power ratings as per Institute of Electrical and Electronics Engineers (IEEE) standards. The influence of the wind turbine in the grid system concerning the power quality measurements are the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation. To mitigate the power quality problems this paper proposes the shunt compensator techniques. Here, the proposed system is verified experimentally using both Static Synchronous Compensator (STATCOM) and Thyristor Switched Capacitor (TSC) compensators. This control schemes for grid connected wind energy system is simulated using Matlab/Simulink.
