“…The model was able to reproduce most of the operating parameters, such as pressure, temperature, mass flow rates and output power. An economic and performance assessment of the ISCC-PTC system in Hassi R'mel (Algeria), coupled with a new thermal storage system was performed [20]. Results revealed that a better grid stability was reached, increasing solar energy conversion and overall performance.…”

The harmful environmental effects of fossil fuels and the variability in their prices are shifting attention away from conventional combined cycle power plants. Supply issues in islands are also a problem to be considered. The objective of this work is to evaluate the feasibility of integrating solar energy into a combined cycle power plant for fuel saving in insular subtropical climates. With this aim, a case study comprising a 93 MW combined cycle in Las Palmas de Gran Canaria (Spain) and the integration of solar energy in the gas upper cycle has been presented and analyzed with a thermodynamic model. The effects of incorporating solar heat before and after the cycle compressor were assessed, finding that injecting 35 MW of solar heat before the compressor resulted in savings of 49% of the original fuel consumption and an increase of 2% in the global cycle efficiency, but at the expense of reducing the net power delivered by 47%. On the other hand, incorporating the solar heat after the compression process resulted in an overall 16.2% increase in the cycle efficiency, while delivering the same net power as the original cycle and reducing fuel consumption in 22%. With the increase in the amount of solar heat added to the cycle, the difference between both options became greater, with the best option being injecting solar heat after the compressor. Estimations of the economic and environmental effects of the most suitable option are provided, resulting in potential overall savings of 7.14 million Euro per year and a yearly potential of 13.75 Mkg of CO2 emissions avoided. The results of this work are expected to contribute to improve energy supply problems by using a renewable energy source and reduce fuel imports, providing more energy stability and security to the inhabitants of islands with similar climates as Las Palmas.

“…Benabdellah et al [16] analyzed, from a thermodynamics point of view, the energy, exergy, and economics of an integrated solar combined cycle (ISCC) power plant situated in Algeria. It was made of two gas turbines of 40 MW each, one steam turbine of 80 MW, which was fed by two HRSGs (heat recovery steam generators), one solar steam generator (SSG), and a solar field of a total area of 183.120 m 2 and comprising 224 parabolic trough collectors (PTC).…”

The hybridization of conventional thermal power plants by the incorporation of renewable energy systems has witnessed widespread adoption in recent years. This trend aims not only to mitigate carbon emissions but also to enhance the overall efficiency and performance of these power generation facilities. However, calculating the performance of such intricate systems using fundamental thermodynamic equations proves to be both laborious and time-intensive. Nevertheless, possessing accurate and real-time insights into their performance is of utmost significance to ensure optimal plant operation, facilitate decision making, and streamline power production planning. This paper explores the novel application of machine learning techniques to predict the performance of hybrid thermal power plants, specifically the integrated solar combined cycle power plant (ISCCPP). These plants combine conventional thermal power generation with renewable energy sources, making them crucial in the context of carbon reduction and enhanced efficiency. We employ three machine learning approaches: the adaptive neuro-fuzzy inference system (ANFIS), ANFIS optimized via particle swarm optimization (ANFIS-PSO), and ANFIS optimized through a genetic algorithm (ANFIS-GA). These methods are applied to the complex ISCCPP, comprising steam and gas turbine sections and a concentrated solar power system. The results highlight the accuracy of ANFIS-based models in evaluating and predicting plant performance, with an exceptional overall correlation coefficient of 0.9991. Importantly, integrating evolutionary algorithms (PSO and GA) into ANFIS significantly enhances performance, yielding correlation coefficients of 0.9994 for ANFIS-PSO and 0.9997 for ANFIS-GA, with ANFIS-GA outperforming the others. This research provides a robust tool for designers, energy managers, and decision makers, offering valuable support in assessing the performance of hybrid thermal power plants. As the world transitions to cleaner energy sources, the insights gained here are poised to have a significant impact on the growing number of these thermal power plants globally.

“…Another way to increase the efficiency, sustainability and reduce fuel consumption of these systems is to use thermal storage to store some of the solar energy when radiation increases, which reduces the environmental effects and operating costs of these cycle. 24 In the field of emergy based analysis, there are a few studies have been performed. For the first time, Aghbashloo and Rosen 25 reformulated exergoeconomic and exergoenvironmental approaches using the emergy concept.…”

The high amount of solar energy as clean and sustainable energy has increased awareness in solar energy concentration, especially in integrated concepts. One of the best and promising hybrid configurations for converting solar energy into power is an integrated solar combined cycle system (ISCCS). In this study, conventional and advanced analysis tools for the ISCCS located in Yazd (Iran) have been investigated. In this paper, thermodynamic simulation, exergy, exergoeconomic, and exergoenvironmental analysis based on Life Cycle Assessment (LCA) have been performed. In addition, an emergy-based concept, including emergoeconomic and emergoenvironmental assessment, has been performed. In-depth analysis of exergy, exergoeconomic, and exergoenvironmental modelling, advanced exergy analysis based on endogenous/exogenous and avoidable/unavoidable parts have been done. In this regard, MATLAB code has been developed for thermodynamic simulation, exergy, exergoeconomic, exergoenvironment, emergoeconomic and emergoenvironment analysis. Furthermore, THERMOFLEX (commercial software) applied for thermodynamic simulation and verification. The Sankey diagram based on each analysis tool has been constructed. Furthermore, the priority of improvement based on each analysis has been identified. The thermal efficiency and net power generation of ISCCS are 48.25% and 419600 kW, respectively. It was obsereved that in most equipment, less than 10% of exergy destruction and cost and environmental impact rates were avoidable/endogenous.
