Abstract Although the penetration of renewable energy in power systems has been substantially increased globally last decade, fossil fuels are still important providing essential flexibility required to reliably maintain system balance. In 2019, more than one quarter generation Europe and over 40% UK’s electricity was from (mainly gas). For achieving net-zero greenhouse gas emission target arou...

The random nature of wind energy is an important reason for the low utilization rate farms. use a compressed air storage system (CAES) can help reduce characteristics power generation while also increasing energy. However, unreasonable capacity allocation CAES results in high capital investment and long payback period. In order to improve economic benefits storage, this paper studies configurat...

With the advent of restructuring in power industry, conventional unit commitment problem systems, involving minimization operation costs a traditional vertically integrated system structure, has been transformed to profit-based (PBUC) approach, whereby generation companies (GENCOs) perform scheduling available production units with aim profit maximization. Generally, GENCO solves PBUC for parti...

Power supply instability in the grid has been exacerbated by rapid development of new energy generation methods. Notably, large-scale storage is most practical solution to this problem. Meanwhile, China, an effective method reusing increasing number abandoned coal mines urgently required. Accordingly, building compressed air (CAES) plants along roadways can serve as a viable while repurposing t...

Flexible combined cooling, heating, and power (CCHP) systems are effective in integrating wind sources. As an attractive, clean, large-scale energy storage technique, the advanced adiabatic compressed air (AA-CAES) can store generate both electricity also provide cooling during expansion under certain conditions. Although AA-CAES has immense potential multi-energy supply systems, CCHP dispatch ...

The increasing integration of large-scale electricity generation from renewable energy sources in the grid requires support through cheap, reliable, and accessible bulk storage technologies, delivering large amounts both quickly over extended periods. Compressed air (CAES) represents such a option, with three commercial facilities using salt caverns for operational Germany, US, Canada, CAES now...

Million cubic meters from abandoned mines worldwide could be used as subsurface reservoirs for large scale energy storage systems, such adiabatic compressed air (A-CAES). In this paper, analytical and three-dimensional CFD numerical models have been conducted to analyze the thermodynamic performance of A-CAES in during charging discharging processes. Unlike other research works, which heat tran...

Compressed air energy storage (CAES) is increasingly investigated as a viable technology for balancing electricity supply and demand. The main purpose of CAES to overcome the intermittent problem when renewable introduced. However, round-trip efficiency (RTE) system commercially developed still low (around 54 %) requires further improvement. This study proposed novel combined cooling, heating p...

In the Compressed Air Energy Storage (CAES) approach, air is compressed to high pressure, stored, and expanded to output work when needed. The temperature of air tends to rise during compression, and the rise in the air internal energy is wasted during the later storage period as the compressed air cools back to ambient temperature. The present study focuses on designing an interrupted-plate he...
