Power Control of Wind Energy Conversion System Using Super Capacitor
摘要
To attain the wind power smoothing control, Wind Energy Conversion System (WECS) using batteries combined with super capacitors is proposed. The feasibility of power smoothing using Super Capacitor for WECS is investigated using a MATLAB simulation. The simulation determines the system configuration which is able to assure the expected energy output to the grid. The proposed energy storage system is able to compensate all types of rapid changes originated by wind speed fluctuations. It is proved that fluctuations in wind power can be eliminated by large storage batteries, whereas small transients in power flow can be eliminated by the super capacitor bank which increases the life of the battery.
