Energy Management Using Battery And Ultra Capacitor Of Wind Turbine Generating System

Wind is the world’s fastest growing energy source today. During normal operation, the wind generating systems have large fluctuations due to sudden wind speed changes. The Possible solution for this problem is to use hybrid energy storage management. Thus the performance of this system can be improved by using battery as well as super capacitor which is integrated with wind turbine generators. It provides an opportunity for better voltage and frequency response. During wind and load demand variations the use of super capacitors helps to prevent the applications from over voltages during short circuit condition and also it avoids the battery operation in high rate of depth discharge regions. Thus this system meets the need by absorbing or delivering the required power to the load. The performance and the analysis are done in a user friendly MATLAB/Simulink environment and Hardware results are compared. Keywords—Ultracapacitor, Battery, Energy Management, DC link capacitor.
