Do energy storage plants have a function of 'peak-shaving and valley-filling'?
Abstract: With the increase of peak-valley difference in China's power grid and the increase of the proportion of new energy access, the role of energy storage plants with the function of "peak-shaving and valley-filling" is becoming more and more important in the power system.
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.
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).
Does energy storage capacity affect annual comprehensive cost?
The annual comprehensive cost is positively related to energy storage capacity when adopting pricing scheme 1, namely when the peak-to-valley price difference shrinks to a certain extent, consumers cannot obtain economic benefits by configuring energy storage.
What is the economic value of user side energy storage?
In , the economic value of user side energy storage is considered in reducing the construction of user distribution stations and the cost of power failure losses. In , the benefits and life cycle costs are considered brought by price arbitrage, demand management and energy storage life cycle of industrial users.
