The "Dual Carbon" strategy is accelerating the formation of a new-type power system dominated by new energy sources. However, the continuous and rapid growth of grid-connected wind and solar power capacity poses significant challenges regarding grid flexibility. These challenges are prominently manifested as insufficient regulation capability, intensified pressure on energy accommodation, rising operational risks, and difficulties in power balancing.

Fully leveraging the regulation and support capabilities of the gigawatt-scale hydropower systems—possessing advantages in both scale and efficiency—is a crucial technical pathway for ensuring power supply and promoting accommodation within the new power system. It is also a key task in implementing the national strategy for integrated hydropower, wind, and solar clean energy bases.

To this end, the editorial office of Distributed Energy has invited the following distinguished scholars to organize a special issue on "Key Technologies for Coordinated Optimization and Flexible Operation of Hydropower, Wind, Solar, and Energy Storage":
