Energy storage system airflow simulation

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 advanced adiabatic compressed air energy storage (AA-CAES)?

The paper establishes a dynamic model of advanced adiabatic compressed air energy storage (AA-CAES) considering multi-timescale dynamic characteristics, interaction of variable operating conditions and multivariate coordinated control.

How do energy storage systems work?

the effective integration of renewable generation, energy storage systems (ESS) play a key role by providing flexibil-ity to manage the intrinsic intermittency of energy sources such as wind and solar.

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.

How is solar energy used in air storage caverns?

Solar energy is introduced to heat the high-pressure air from the air storage cavern to improve the turbine inlet air temperature. An ORC was introduced to recover the heat carried by the air-turbine exhaust.

How is compressed air released during discharging?

During discharging, air is released, either heated by burning fuel or stored thermal energy to generate electricity , . Compressed air is stored in underground caverns or up ground vessels , . The CAES technology has existed for more than four decades.
