Synergetic control of super capacitors energy storage system

As a new energy buffer for electric vehicle and renewable energy, a super capacitor energy storage system can storage and release large charge energy rapidly. Based on power conservation theorem, a synergetic controller is provided to regulate the discharging and charging of super capacitor energy storage system during large change range of operating point. The parameters of synergetic controller have clarity physical meaning and could be designed easily. The simulated results verify the excellent qualities of this system, which improved the control precision and stability of the super capacitor energy storage system.
