How can energy storage reduce load peak-to-Valley difference?

Therefore, minimizing the load peak-to-valley difference after energy storage, peak-shaving, and valley-filling can utilize the role of energy storage in load smoothing and obtain an optimal configuration under a high-quality power supply that is in line with real-world scenarios.

Does energy storage play a role in peak shaving and valley filling?

Peak and Valley Constraints In order to play the role of energy storage in peak shaving and valley filling, the load power value of the grid connection point after energy storage is configured should float within the load power curve range when energy storage is not configured.

Can a power network reduce the load difference between Valley and peak?
