| Abstract: |
| Doubly-fed variable-speed pumped storage units(DFVSPSUs) are not limited to rated speed ope-ration and have become as a new direction and research hotspot in the field of pumped storage energy. The social demand and development status of DFVSPSU at home and abroad are introduced, and the principle of DFVSPSU is outlined and its characteristics are summarized. The typical application scenarios of DFVSPSUs are categorized combined with their characteristics. The current research status and major issues related to key technologies such as converter technology, control technology, unit design, and manufacturing technology are addressed. Furthermore, future development of DFVSPSUs is considered and prospected. |
