“…The calculated solar to electric efficiency for one-stage ISCC and two-stage ISCC plants are 28.6 and 29.8 %; moreover, the system exergy efficiency are 58.4 and 60.9 %. Rovira et al (2016) compared the annual performance and economic feasibility of the integrated solar combined-cycle plants using parabolic trough collector and linear Fresnel reflector. The reported LCOE for ISCC plant with PTC field (cost 200 €/m 2 ) is 9.42 c€/kWh for Almeria, Spain and 5.58 c€/kWh for Las Vegas, USA.…”

Concentrated solar power (CSP) plant is an emerging technology among different renewable energy sources. Parabolic trough collector (PTC)-based CSP plant, using synthetic or organic oil as a heat-transfer fluid, is the most advanced technology. About 87 % of the operational capacities of CSP plants worldwide are based on PTC technology. Direct steam-generating linear Fresnel reflector (LFR) systems have been developed as a cost-effective alternative to PTC systems. Line-focusing concentrating solar collectors (PTC and LFR), with single-axis tracking, are simple in design and easy to operate. Prior to the detailed design of a CSP plant, it is necessary to finalize type of the solar field, type of the power-generating cycle, overall plant configuration, sizing of the solar field and the power block, etc. The optimal design of a CSP plant minimizes the levelized cost of energy for a given site. In this paper, a detailed review of important design parameters which affect the design of line-focusing concentrating solar collector-based power plants is presented. This includes parameters for solar collector field design, receiver, heat-transfer fluid, thermal energy storage, powergenerating cycle, sizing and configuration of the plant, etc. This review may provide a reference for designing CSP plants. Future research directions are also identified.

“…A number of studies have been reported comparing between parabolic trough and linear Fresnel applications [22][23][24][25][26][27][28][29][30][31][32]. Lined focused parabolic and linear Fresnel solar concentrators [22] both consist of a long reflector, which act as the only concentrator aligned on a north-south axis.…”

“…Figure 2 shows the layouts of the solar hybrid combined cycles based on LFR. In the case of solar integration into the steam cycle ( Figure 2a) the layout also corresponds to an ISCC in which the solar energy is used to evaporate part of the water at the high pressure level in parallel with the corresponding evaporator [33]. The configuration is named as LFR-DSG.…”

This paper compares the annual performance of Integrated Solar Combined Cycles (ISCCs) using different solar concentration technologies: parabolic trough collectors (PTC), linear Fresnel reflectors (LFR) and central tower receiver (CT). Each solar technology (i.e. PTC, LFR and CT) is proposed to integrate solar energy into the combined cycle in two different ways. The first one is based on the use of solar energy to evaporate water of the steam cycle by means of direct steam generation (DSG), increasing the steam production of the high pressure level of the steam generator. The other one is based on the use of solar energy to preheat the pressurized air at the exit of the gas turbine compressor before it is introduced in the combustion chamber, reducing the fuel consumption. Results show that ISCC with DSG increases the yearly production while solar air heating reduces it due to the incremental pressure drop. However, air heating allows significantly higher solar-to-electricity efficiencies and lower heat rates. Regarding the solar technologies, PTC provides the best thermal results.
