Which energy storage technologies reduce peak-to-Valley difference after peak-shaving and valley-filling?

The model aims to minimize the load peak-to-valley difference after peak-shaving and valley-filling. We consider six existing mainstream energy storage technologies: pumped hydro storage (PHS), compressed air energy storage (CAES), super-capacitors (SC), lithium-ion batteries, lead-acid batteries, and vanadium redox flow batteries (VRB).

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.

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

A simulation based on a real power network verified that the proposed strategy could effectively reduce the load difference between the valley and peak. These studies aimed to minimize load fluctuations to achieve the maximum energy storage utility.

What is the peak-to-Valley difference after optimal energy storage?

The load peak-to-valley difference after optimal energy storage is between 5.3 billion kW and 10.4 billion kW. A significant contradiction exists between the two goals of minimum cost and minimum load peak-to-valley difference. In other words, one objective cannot be improved without compromising another.
