Compressed air energy storage modeling

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.

What is a model of compressed energy storage process?

A model of the compressed energy storage process considering inlet guide vane angle control, outlet throttle control, and speed control has been established. A model for the expansion power generation process considering inlet throttle control, nozzle angle control, and speed control has been established.

What are the dynamic models of adiabatic air storage chamber and heat storage tank?

The dynamic models of the air storage chamber and the heat storage tank were established using the dynamic modeling method proposed in reference . The dynamic models of the equal capacity adiabatic air storage chamber and the regenerative dual tank liquid heat storage tank were established separately.

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.

Can compressed-air energy storage stabilize wind farms under grid fault conditions?

H. T. Le and S. Santoso, “Operating compressed-air energy storage as dynamic reactive compensator for stabilising wind farms under grid fault conditions,” IET Renewable Power Gener., vol. 7, no. 6, pp. 717–726, 2013.

How can A CAES compressor be modeled?

Under these assumptions, the CAES compressor could be modeled using two stages of the compression-heat-exchanger illustrated in Fig. 3, with j representing the = 1 low-pressure compressor, and j = 2 the high-pressure compressor. Hence, the tempera-ture gain ̇mc) and compressor’s stage power Γ2( constant Φ2 become: ̇mc) Γ2( = 1 + Fig. 5.
