| Abstract: |
| A hybrid energy storage system composed of battery and superconducting magnet is designed to suppress the power output fluctuation of intermittent source and its basic principle is analyzed. The topological structure of the grid-connection equipment for intermittence power source and the hybrid energy storage system，as well as the interfaces between them，are presented. A dual-layer energy storage control system is designed and implemented. Its central control unit applies the moving average filter to extract the low frequency components from the power order and assigns them to the battery，while the remained fast changing components to the superconducting magnet. The local control unit adopts PI control regulation to force the battery and superconducting magnet following the power order and voltage order respectively. The effectiveness of the designed system and control method is verified by the results of simulation with PSCAD／EMTDC. |
