“…Typically, the maximum operating temperature for these HTFs is restricted by their thermal stability (up to about 400°C). Direct steam generation in PTC system is also proposed as an economically viable option (Zarza et al 2002). However, the performances of CSP plants with direct steam-generating PTC field still have to be demonstrated at larger scales .…”

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.

“…In reference [7], the one-dimensional and two-dimensional thermal oil solar parabolic collectors' models were developed using EES software, and validated with experimental data. Zarza et al [8,9] and Eck and Steinmann et al [10] presented the simulation results of the solar direct steam generation in parabolic trough test facility in Almeria Solar Platform in Spain. Besides, the simulated results have been compared with the test data in reference [10].…”

SUMMARYA dynamic model of solar parabolic trough collectors has been developed and solved by explicit Euler's method to predigest partial differential equations to ordinary differentials in this paper. Different working conditions of the collector structure and thermal parameters have been considered in the model. The simulated results are validated using the selected real test data on typical summer and winter days, and the steam-generating process from unsaturated water to superheated steam has been studied in the startup simulation. The disturbance analysis validates the model's dynamic responses and confirms the relations between output steam characters and solar radiation, inlet water temperature, flow rate and collectors' area. The results indicate the possible demarcation point of superheated steam generating in different working conditions. Therefore, the model can be used to analyze the performance of the solar direct steamgenerating system.

“…The modeled system has been able to estimate response of the plant very accurately. Modeling of parabolic trough collector at 'DISS project'-A solar thermal power plants with DSG-has been presented by Zarza et al [7]. For Direct Steam Generation with dish concentrators, researchers at Australian National University have been working since the last three decades [8].…”
