“…For example, Pomponi et al [179] proposed a Monte Carlo analytical method, which took uncertainty random modeling as the input and incorporated uncertainty analysis into the life cycle assessment. In addition, Xiao et al [180] performed uncertainty analysis for the life cycle evaluation of solar thermal power plants with an integrated air-cooled supercritical CO 2 Brayton cycle and investigated the effects of the solar irradiation, ambient temperature, turbine inlet temperature, lifetime, and TES capacity on the LCA results.…”

In order to pursue clean, low-carbon, safe, and efficient energy utilization and accelerate the development of new energy, sustainability is the necessary research. In recent decades, solar power generation has rapidly formed and been widely applied. Sustainability analysis is a key aspect that directly affects the construction of solar power projects when conducting solar power generation construction. This paper attempts to start with life cycle sustainability assessment (LCSA) and study the status quo of its three pillars (These three pillars include life cycle assessment, life cycle cost assessment, and social life cycle assessment) in the field of solar power generation. At the same time, the externality indicators are considered between pillars. In addition, the application of uncertainty analysis was studied during the analysis process to address the impact of various random factors. The conclusion shows that further research is needed to support this transition by integrating life cycle assessment, life cycle cost, and social life cycle assessment into LCSA for the evaluation. To improve the effectiveness of future research, studies should focus on fulfilling major data gaps in the literature such as the lack of detailed documentation for specific materials and background process choices in life cycle assessment databases. The development of solar power generation can be an important alternative in efforts to decrease climate change impacts and pursue cleaner energy sources in countries where solar energy is more easily available by integrating life cycle assessment (LCA), life cycle cost (LCC), and social life cycle assessment (SLCA) into LCSA. The sustainable development of the solar power generation industry in terms of multiple aspects is supported.

“…Furthermore, thermal energy can be integrated with an on-site fossil fuel backup system, or it can be stored for later use at a low cost compared to a battery-powered backup system. As per the IEA report in October 2021 [5], solar thermal energy system (STES) is predicted to reach a capacity of 21.5 GW in 2022, up from 15.5 GW. In addition to STES, another alternative form of green energy produced from the thermodynamic process of energy conversion (i.e.)…”

The emergence of micro‐sources in the energy market to reduce carbon emissions and exploit more renewable generations increases the frequency oscillations of the system. Hence, this paper attempts to develop a robust nonlinear fractional order proportional integral derivative (NLFOPID) controller for frequency regulation of restructured energy systems. A hybrid atom search‐particle swarm optimization (AS‐PSO) is proposed to optimize the gain values of the NLFOPID controller. The proposed control approach enhances flexibility by providing robustness against the RE intermittency. The optimization technique is coded in MATLAB and applied for frequency regulation of a multi‐area energy system developed in Simulink. Initially, the effectiveness of the hybrid algorithm is validated for standard benchmark functions and then implemented for frequency control. The results demonstrate that the proffered AS‐PSO technique performs significantly for various types of transactions in a deregulated energy market than state‐of‐the‐art. The real‐time applicability of the proposed controller is validated using hardware‐in‐the‐loop simulation of the open energy market in OPAL‐RT. The frequency response obtained from the AS‐PSO optimized NLFOPID controller is remarkable compared to other techniques. Furthermore, the closed‐loop stability of the system is examined using bode analysis through an improved Oustaloup approximation technique.

“…The supercritical CO 2 Brayton cycle (sCO 2 ) is highly recommended as one of the promising technical solutions due to its high cycle efficiency, compactness, fine security and simple cycle layout [1][2][3][4]. Therefore, many studies have been undertaken in this field from different aspects, including cycle layouts [5,6], performance analysis [7,8], components design, and system optimization [9][10][11].…”

A novel closed Brayton cycle is proposed that integrates a supercritical CO2 or CO2/xenon mixture as working fluid with the ORC in this paper.. The parametric study is performed to evaluate the impacts of some key parameters on the performance of the combined system, including the pressure ratio in sCO2, inlet temperature of turbine1 and evaporation temperature Results indicate that CO2/xenon mixture can improve the thermodynamic performance of the combined system, which brings the highest exergy efficiency of 58.80%. At the same time, CO2/xenon mixture presents lower efficiency and power.
