Simulating compressed air energy storage

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.

Is compressed air energy storage a solution?

A Com pressed Air Energy Storage (CAES) appears as a solution to this disadvantage. A model that reflects the instant behavior of a system building and the power grid is proposed in order to evaluate its feasibility. involved are presented in t his paper. This model allows to assess the size of these autonomy.

Is adiabatic compressed air energy storage efficient?

An adiabatic compressed air energy storage system with thermal storage was studied. The dynamic behaviour of the system is evaluated using an algebraic/differential model. The link between components and system performance is elucidated. The round trip efficiency reaches 70% when thermal storage efficiency is 95%.

How many large scale compressed air energy storage units are there?

For example, there are two large scale Compressed Air Energy Storage (CAES) units in the world. The first, in Huntorf, Germany operating since 1978 which can generate 290 MW for 2 h and the second, in McIntosh, Alabama, USA operating since 1991 with a 110 MW capacity up to 26 h.

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 is CAES system model simulation?

The compressed air energy storage (CAES) system is a very complex system with multi-time-scale physical processes. Following the development of computational technologies, research on CAES system model simulation is becoming more and more important for resolving challenges in system pre-design, optimization, control and implementation.
