| Abstract: | Ultracapacitor can be used as energy storage element in power quality adjustment device of distribution network and provides necessary energy buffering. The working principle of constant voltage bi-directional power flow in Ultracapacitor energy storage device is analyzed in detail and corresponding system model is established. According to the feature of Ultracapacitor the method to design Ultracapacitor energy storage device is given in which the occurrence of system's nonstationary pole of open-loop transfer function is effectively avoided, and smooth shift between the energy storage modality and energy release modality is realized by unified controller. Testing results show that this control strategy is effective and feasible. |
