Pumped Storage Hydropower and Advanced Energy Storage Technologies for Flexible and Resilient Power Systems

---

Introduction:

With the increasing penetration of renewable energy sources, such as wind and solar photovoltaic power, and the growing complexity of electricity demand characteristics, fluctuations in power generation and uncertainties in load demand are becoming increasingly pronounced. These challenges impose higher requirements on power balancing, operational flexibility, and frequency and voltage stability. Meanwhile, the increasing occurrence of extreme weather and other natural hazards further complicates secure grid operation and fault recovery. Pumped storage hydropower (PSH), characterized by its large energy storage capacity, long storage duration, and dual-mode pumping and generating operation, plays an important role in enhancing power system flexibility and resilience. Emerging energy storage technologies provide complementary regulation capabilities through their diverse response speeds, storage durations, and operational characteristics. To improve the performance of energy storage equipment and grid-support capabilities, further research is needed to elucidate the multiphysics coupling mechanisms and dynamic response characteristics of pumped-storage units under complex operating conditions, and to investigate the optimal design of key equipment and control strategies for wide-range operation based on these findings. Research is also needed on energy conversion, energy management, and grid-connected control technologies for emerging energy storage systems, as well as optimal power system dispatch strategies incorporating energy storage and methods for enhancing power system resilience.

The topics of interest include, but are not limited to:

1. Operating characteristics and control strategies of variable-speed pumped-storage units
2. Optimal design methods for pumped-storage motor-generators and key equipment
3. Multiphysics analysis and thermal management methods for pumped-storage units
4. Wide-range operating performance and reliability assessment of pumped-storage units
5. Operational optimization and multi-timescale scheduling methods for pumped-storage power plants
6. AI-enabled condition assessment and intelligent operation and maintenance of energy storage systems
7. Energy conversion and performance assessment of emerging energy storage systems
8. Energy management and grid-connected control methods for emerging energy storage systems
9. Grid-support capability assessment and stability analysis of pumped storage hydropower and advanced energy storage systems
10. Assessment and enhancement methods for energy storage-supported power system resilience under extreme weather conditions
