“…Furthermore, the opportunity and robustness problems are used to providing bidding/offering strategy for the proposed merchant CAES system. A combined cooling and power system to improve the energy efficiency of the air compressor for a CAES system is proposed in [7]. The purpose of this method is to study the effects of parameters such as the ambient temperature, the volumetric flow ratio, and the temperature of the expander input, on the performance of the system.…”

This paper evaluates the self-scheduling problem for solar-based compressed air energy storage (CAES) plant with capability of compression waste thermal energy recovery via information gap decision theory (IGDT) approach. This feature gives the plant the ability to make income through participation in the thermal energy market. Moreover, the proposed plant uses natural gas as input fuel, which makes the system flexible to operate as a simple cycle gas generator when the stored air is drained. The utilisation of renewable energies in spite of many benefits has some challenges to self-scheduling of the solarbased three state CAES plant such as volatility and unpredictability. In addition, the uncertain solar farm generation is modelled by IGDT method. By the proposed IGDT model, the plant can pursue risk-taker and risk-averse strategies to face with different situations related to uncertain parameter. Finally, the numerical results obtained from case studies validate the appropriateness of the proposed approach.

With the development of the power system, wind energy was applied to micro-grid system as a distributed generation. The output of the wind farms has the characteristic of intermittence and fluctuation, which would influent the stability of micro-grid system and can be solved effectively by compressed air energy storage system, a new energy storage technology. Because of the advantage of fast response, high economic performance and small environmental impacts, it has an extensive application prospect. This paper builds a micro-grid system with wind power generator, and control the output of micro-grid system by using compressed air energy storage system. The simulation result verifies that the compressed-air energy storage system can effectively suppress power fluctuation and improving the stability of the micro-grid system.

“…Compressed air energy storage (CAES) is the most suitable large-scale energy storage method besides pumped hydro storage. The main advantages of this method include large power capacity, long storage times, low costs, and lesser environmental impact compared to pumped hydro storage [1]. The CAES can be divided into recuperative and non-recuperative types.…”

Existing research on layout parameters of compressed air energy storage (CAES) cavern groups in hard rock has indicated that the key influential factors for group stability include buried depth, diameter, and cavern spacing. Among these, in contrasting to other factors, the research on cavern spacing is limited. This paper focuses on the issue of safe spacing and proposes a numerical method to determine it. By establishing a series of finite element models, the stress state of surrounding rock, changes in shape, equivalent plastic strain of plastic zone, and cavern wall deformation under different spacing have been studied. When a group of air storage caverns in rows is subjected to high internal pressure, for a small spacing, the plastic zone of the surrounding rock between two caverns is connected. Here, the size of the plastic zone, equivalent plastic strain value, and deformation of the cavern wall are relatively large, making the surrounding rock highly susceptible to damage. As the spacing increases, the horizontal width of the plastic zone, the maximum equivalent plastic strain value, the displacement changes of the cavern wall remain stable. This spacing is virtually the same as that when the plastic zone of the surrounding rock is no longer connected and can be selected as a safe spacing. This study explores the design of cavern safe spacing of underground CAES cavern groups and discusses several influencing factors, which can provide references for follow-up energy storage engineering and research.
