According to the mathematical model of voltage source converter,the real-time power control is studied to enhance the dynamic power tracking characteristics of UC(UltraCapacitor) energy storage system based on the decoupling control of AC-side currents under d-q synchronous reference frame.The DC-DC converter for connecting UC with the voltage source converter is designed and the control strategy for compensating DC voltage variation by UC charge / discharge is realized.Simulative results show that,the prop...
