Abstract—Interfacing converters utilized in connecting energy storage systems like ultra capacitors and battery banks to wind generation systems introduce additional cost and power losses. This paper thus presents an immediate integration theme for ultra capacitors utilized in mitigating short-run power fluctuations in wind generation systems. This theme uses a dual electrical converter topology for each grid affiliation and interfacing a ultra capacitor bank. The most electrical converter of the dual electrical converter system is hopped-up by the corrected output of a wind turbine-coupled permanent-magnet synchronous generator. The auxiliary electrical converter is directly connected to the ultra capacitor bank. With this associate interfacing converter is not needed, continuity of load maintenance is possible and there are not any associated cost and power losses incurred. The performance of the proposed system is evaluated in MATLAB/ SIMULINK software. Finally, the Simulation results shows that the short-run fluctuations is suppressed and posses the desired characteristics in wind energy systems.
