Hybrid energy storage system using wind power system

The research deals with energy storage and its management. In this hybrid wind system Li-ion battery charge status is controlled by DC/DC bidirectional converter based on load requirement. The battery system along with super- capacitor and load are being simulated for various conditions and the output parameters like voltage, current, power and state of charge are being plotted and analyzed for each condition. To meet the short-term peak, it is required to charge the power at a faster rate by using a super-capacitor. To meet medium-term peak requirement, it is required to fulfill the largescale capacity by using Li-ion battery. The life of Li-ion battery depends upon the charging and discharging cycles. By using a super-capacitor, the efficiency and durability of the battery is increased by reducing the charge and discharge cycle of the battery. Due to this the maintenance cost of the battery is reduced, which reflects the overall cost of the system. Model is proposed with external energy maximization strategy (EEMS) and simulated on MATLAB R2015 b. This paper depicts the control and management strategy for the reduction of deviation cost by utilizing hybrid energy storage system by which we obtained a much more cost-effective solution as compared to conventional system.
