Abstract: The synergetic development of pumped storage and new energy storage plays a positive role in promoting the transformation of energy structure,but there is no consensus on how to synergize the development of pumped storage and new energy storage in order to adapt to the construction process of the new power system.Based on the analysis of different time scale energy storage needs of the new power system and the development status of energy storage,the functional localization and development trends of pumped storage and new energy storage are clarified.Based on planning positioning,technological innovation,operation and maintenance management,and operational strategy architecture,we propose suggestions for the coordinated development of pumped storage and new energy storage to meet the needs of the new power system construction.This provides strategic support for promoting the decision-making and healthy development of the energy storage industry.
