Compressed air energy storage peak load regulation

Can a new compressed air energy storage system improve peak power management?

The results of the case study have revealed that the novel compressed air energy storage system for trigeneration could be a very effective and economical system for the management of peak power by providing combined cooling, heating and electricity generation. With a careful selection of the need in different seasons.

What is a novel compressed air energy storage system?

System description Based on electrical energy peak load shifting, a novel compressed air energy storage system for the trigeneration of electricity, heating and cooling power is proposed for hotels, hospitals or other large public buildings. The schematic of the novel type of system is shown in Fig. 1.

Can a compressed air energy storage system be applied to public buildings?

Unlike the conventional compressed air energy storage (CAES) system and related technology, which relies on unique geological or needs plenty of renewable energy likes solar or wind energy, the proposed system in this work can be the applied to public buildings in metropolis. It is an environment-friendly system.

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) technology has received widespread attention due to its advantages of large scale, low cost and less pollution. However, only mechanical and thermal dynamics are considered in the current dynamic models of the CAES system. The modeling approaches are relatively homogeneous.

Why does compressed air storage system need to be improved?

However, due to the characteristics of compressed air storage system, the heating and cooling energy can not be constantly produced. So the system needs to be improved to meet the continuous heating / cooling requirements of users.

What is advanced adiabatic compressed air energy storage?

Advanced adiabatic compressed air energy storage based on compressed heat feedback has the advantages of high efficiency, pollution-free. It has played a significant role in peak-shaving and valley-filling of the power grid, as well as in the consumption of new energy.
