Due to limited fossil fuel resources, a growing increase in energy demand and the need maintain positive environmental effects, concentrating solar power (CSP) plant as promising technology has driven world find new sustainable competitive methods for production. The scheduling capability of CSP equipped with thermal storage (TES) surpasses photovoltaic (PV) unit augments sustainability system ...

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...

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...

Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air may be isochoric (constant volume) or isobaric pressure). Isochoric storage, wherein internal pressure cycles between an upper and lower limit system charges discharges mechanically simpler, however, it leads to undesirable thermodynamic co...

Underwater compressed air energy storage (UWCAES) is founded on mature concepts, many of them sourced from underground compressed air energy storage technology. A fundamental difference between the two systems is the way in which air is stored. UWCAES utilizes distensible boundary, submerged air accumulators as opposed to rigid walled caverns. This paper presents an analysis of the primary desi...

We consider a small-scale overground compressed-air energy storage (CAES) system intended for use in micro-grid power networks. This work goes beyond previous efforts the literature by developing and showing results from first-of-a-kind (20 kWh) near-isothermal CAES employing novel, reversible liquid-piston gas compressor expander (LPGC/E). Additionally, we extend our study to assessments, firs...
