“…ISCCs are composed of a Concentrated Solar Power plant (CSP) and a Natural Gas-Fired Combined Cycle (NGCC). The CSP plant is normally used either to produce additional steam for use in the NGCC's steam turbine [5,6], or to preheat the compressed air in the gas turbine before entering the combustion chamber [7]. Among the main four types of collectors that are used in CSP plants, Parabolic Trough Collectors (PTC) represent the most mature concentrated solar power technology.…”

Energy is one of the most basic elements of the universe that is essential for all life processes. The problem facing the world nowadays is the diminishing of fossil fuel resources and the increasing of emissions to the atmosphere, thus world attention is now going to the utilizing of renewable energy sources. The aim of this paper is to evaluate the potential fuel savings that could be achieved by integrating a parabolic trough collector solar power plant into an existing natural gas combined cycle in the city of Alexandria, in Egypt, where direct solar radiation levels are high all year, varying from 2,000 kWh/m 2 to 3,200 kWh/m 2. The Integrated Solar Combined Cycle (ISCC) has been modelled in Matlab, using Simulink to couple a control system that simulates the operation of the hybrid plant under fuel saving mode. The results show that the tested system achieves good fuel saving, reaching 436,000 $/year in case of controlling the amount of oil that passes in the parabolic collector and 165,625 $/year in case of not controlling the amount of oil with a percentage of 38 % of the first case.

“…Another technology is concentrating solar power (CSP) for electricity generation . In this approach, solar radiation is concentrated in order to heat a fluid which runs turbine and electricity generator . Most of CSP plants use fossil fuels as back‐up to generate electricity when solar radiation is not adequate to run turbine .…”

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.

A calculation method for the evaluation of the performance of a 50 MW hybrid solar plant with linear air collectors and an open Joule-Brayton air cycle, equipped with an interrefrigerated compressor, a regenerator and a natural gas combustor has been developed. If the plant is operated each day between sunrise and sunset for an entire year in conditions close to nominal ones, the net electricity produced in one year is 244,000 MWh, the fuel consumption is 34,575 tons of natural gas, the annual average efficiency of solar collectors is 49.8%, the average thermodynamic efficiency of power block is 42.1%, the average conversion efficiency of solar energy to electricity is 20.9%. The saving of fossil fuel due to the employment of solar energy in the hybrid plant is 22%, the cost of electricity produced results to be 8.3 cents$/kWh. This value is competitive with that of other plants using renewable energy.
