Dispatching of compressed air energy storage power stations

How does compressed air energy storage work?

Another point that needs to be explained for CAES is that compressed air energy storage has the ability to switch working conditions quickly. The working condition conversion from maximum power generation to maximum compression power can be realized within 5 min, and the start-up time of the power generation mode is about 11 min [ 45 ].

Can adiabatic compressed air energy storage improve grid frequency security?

The advanced adiabatic compressed air energy storage (AA-CAES) is a promising solution to enhancing grid frequency security due to its flexible and high inertia properties. Therefore, based on distributionally robust optimization, this paper proposes a dispatch strategy with the participation of AA-CAES to enhance frequency security.

What is compressed air energy storage (CAES)?

As an energy storage technology, compressed air energy storage (CAES) has the unique advantages of electricity-thermal joint storage and joint supply, long life cycle, and low installation cost.

Can compressed air energy storage improve ramp rate?

Integration of compressed air energy storage and gas turbine to improve the ramp rate Considering thermodynamic characteristics of a CAES facility in self-scheduling in energy and reserve markets IEEE Transactions on Smart Grid, 9 ( 4) ( 2018), pp. 3476 - 3485 Hypothesis of thermal and mechanical energy storage with unconventional methods

What are the components of AA-CAES power station?

The framework of the AA-CAES power station is presented in Fig. 1. The AA-CAES plant consists of low/high-pressure compressors, low/high-pressure turbines, motors/generators, heat exchangers (HEX), air reservoirs, hot/cold heat reservoirs, and other auxiliary devices.

What are the main components of a compressed air system?

The largest component in such systems is the storage medium for the compressed air. This means that higher pressure storage enables reduced volume and higher energy density.
