6 FAQs about [Peak-valley energy storage system capacity selection]

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).

What is the energy storage technology selection and capacity allocation model?

The proposed model provides quantitative decision-making guidance for formulating a country's energy storage technology selection and capacity allocation schemes.

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.

What is the optimal energy storage capacity?

The optimal energy storage capacities were 729 kWh and 650 kWh under the two scenarios with and without demand response, respectively. It is essential for energy storage to smoothen the load curve of a power system and improve its stability .

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.

What are the parameters of an energy storage system?

Other parameters include the unit transmission cost, load, power demand, upper and lower limits of the energy storage ratio, lower limits of the installed RE ratio, and maximum incoming/outgoing capacity.
