“…Adding some component such as recuperative and thermal energy storage to the cycle enables efficiency improvement of the cycle . Grange et al added a thermal energy storage (TES) unit to the power plant as shown in Figure . There were three modes for the thermal storage unit including idle, discharge, and charge.…”

“…Studies conducted on hybrid solar gas turbine systems are growing due to improvement in cycle efficiency and decrease in water and fuel consumption when combined cycle is running. 44,45 Moreover, integrating solar energy with gas turbines, reduce levelized cost of generated electricity and carbon dioxide emission. 46 For instance, Dabwan et al 46 conducted a study on integrated solar-natural gas power plants and concluded that levelized cost of generated electricity decreased in the range of 75%-86% relative to the fullysolar-powered LFR (Linear Fresnel Reflector) power plant.…”

The thermal energy of the sun can be used for electricity generation. Solar thermal energy can be applied with fossil fuels or independently in order to reduce the cost of generated electricity and CO2 emission. Several cycles are introduced to extract solar thermal energy to be used in power plants. Brayton cycles, Rankine‐Brayton cycles, and supercritical Brayton cycles are among the most conventional ones. Based on the reviewed researches, using solar energy in addition to fossil fuels results in lower carbon dioxide emission and lower levelized cost of the generated electricity. Moreover, thermodynamic and economic analyses of the cycles revealed that heat recovery leads to higher efficiency while increase capital cost. The efficiency of solar‐assisted gas turbines depend on various parameters including pressure ratio, turbine inlet temperature, heat absorber geometry and the performance of the components. The enhancement in the efficiency of the cycles by applying each method depends on the configuration, operating condition. For instance, results have shown that 10% increase in turbine efficiency can led to 6%‐12% improvement in the efficiency of a closed‐Brayton cycle.

The present work presents a very detailed techno-economic analysis of the technology made up of two complementary models. A performance model implemented in Thermoflex environment is used to explore alternative integration layouts to enable the simultaneous operation on solar and fossil energy. Then, a detailed cost analysis approaches the capital and operation costs of the plant from an EPC (Engineering, Procurement and Construction) standpoint. These two models are then combined in annual simulations to obtain the final Levelized Cost of Electricity from which a solid conclusion about the true potential of solar gas turbines can be ascertained. A sensitivity analysis with respect to the main boundary conditions is also provided.

In this paper, a solar tower power plant with a closed Joule-Brayton cycle, of 5 MW rate power, with molten salts thermal storage, located in Seville is presented. The peculiarity of the cycle, using air like fluid work, is to vary, by an auxiliary compressor and a vent valve, the pressure, so that fluid average density, at gas turbine inlet. An adjustment of the mass flow rate, in order to regulate the exit air temperature from the receiver of concentrating solar tower, is obtained. During energy surplus production, the thermal storage energy is loaded. Particular attention is placed to the energy thermal storage, which uses molten salt KCl-MgCl2, suitable for this application due to its high melting temperature, in double tank configuration. The thermodynamic model of the entire plant was implemented using Thermoflex ® software, while, for the concentrating tower, WinDelsol software was used. Using time data relating to the locations, the performance of the entire plant, during a year, has been simulated. Preliminary results show that this plant can achieve relevant benefits in total energy production and equivalent operation hours per year, therefore it is competitive with conventional energy production systems. Furthermore, a performances estimation with a cost analysis, using a LCOE parametric analysis, has been performed.
