“…The solar field concentrates the solar radiation onto a specific point or line to heat an HTF. The heated HTFs can be used directly or indirectly [17]. In the direct case, water is used as HTF for direct steam generations; whereas in the indirect case, different HTFs such as synthetic oil, molten salt, and Therminol VP-1 are used to heat water for a steam generation [17].…”

Performance and Economic Analysis of Concentrated Solar Power Generation for Pakistan

In Pakistan, the utilization of renewable energy sources is increasing in order to reduce the electricity supply and demand gap. However, concentrated solar power (CSP) generation has not been considered in the country even though it has gained considerable attention worldwide. This study, as such, investigates the potential, performance, and economic analyses of four CSP technologies for different locations in Pakistan. Initially, an assessment of CSP sites, including solar resource, land, and water availability, was undertaken. Then, performance simulations of CSP technologies for four different locations of Pakistan, namely Quetta, Hyderabad, Multan, and Peshawar, were examined. For all cases, highest energy production was achieved in summers and lowest in winters, and CSP plants with evaporative cooling were found to be efficient compared to air cooling. The results also revealed that the Quetta and Hyderabad regions were promising for CSP development while parabolic tough (PT) and solar power tower (SPT) were the suitable CSP technologies for these regions. Specifically, the SPT plant with air cooling could be a favorable option for energy production in Quetta. Lastly, economic analyses revealed the financial feasibility of CSP plants in Pakistan since the levelized cost of energy is found to be significantly low.Processes 2019, 7, 575 2 of 26 negligible. Specifically, an abundant potential of solar energy is available in the country because of its location in the sunbelt. Solar energy can be utilized in two ways: solar photovoltaics (SPV) and concentrated solar power (CSP) [4]. SPV systems are used to convert sunlight directly into electricity whereas CSP systems (also known as solar thermal systems) are used for concentrating and heating a heat transfer fluid (HTF) for a power cycle. In Pakistan, the installation and development of the SPV system is growing [4]. Quaid-e-Azam solar park (QASP), which is the first ever power station in the country consisting of SPV with a capacity of 1000 MW, is under construction [4]. Out of 1000 MW of QASP, 300 MW has been already added to the national grid. Also, several small to large scale projects consisting of solar photovoltaics are under operation and construction [4]. However, CSP systems have not been utilized in Pakistan.CSP is a promising technology for large scale power production. There are four families of CSP technology including (i) parabolic trough collectors (PTC), (ii) solar power tower (SPT), (iii) linear Fresnel reflects (LFR), and (iv) parabolic dish systems (PDs). There are numerous advantages of CSP, such as renewable, clean, low operating cost, etc. However, one of the issues with CSP is soiling of mirrors, where dirt is accumulated on the mirrors/reflectors. It causes a reduction in the electricity production. The soiling effect can be reduced by proper cleaning/washing of the mirrors [5][6][7]. The commercialization of CSP is increasing. For instance, the CSP global capacity was 400 MW in 2006, which increased to 4800 MW in 2017 [8]. The global l...

“…CSP with TES offers considerable flexibility, increasing its own value to the grid and even enabling greater grid penetration of variable-generation technologies such as photovoltaic power plants [15,16]. Instead of examining the feasibility of implementing PT-CSP in Palestinian territories as introduced in [17][18][19][20][21], this paper inspects the effect of dispatchability of PT-CSP power plants over PV power systems. The electrical system in Jericho suffers from frequent interruptions in the night hours especially in summer; this makes PT-CSP power plants with TES better than the PV system.…”

This paper investigates the impacts of dispatchability of Parabolic Trough Concentrated Solar Power (PT-CSP) systems over PV power plants in Palestinian territories. Jericho governorate was taken as a case study. All conditions required for implementing PV and PT-CSP systems are verified. The capacity of each investigated system is 1 MW, and both systems are investigated in terms of technical, economic, and environmental aspects. The parametric analysis is used to identify the most feasible option of each renewable energy system by varying the cost of each option candidate and introducing thermal energy storage (TES) to the technology of PT-CSP systems with different capacities. A software based on the MATLAB environment is programmed to estimate the energy produced from each system with the important technical, financial, and environmental indicators. It is found that the alternative of installing a 1 MW PV system is the installation of 1 MWe PT-CSP systems with 14.5 h or 18.5 h TES. Introducing TES improves the dispatchability of the system and the capacity factor which consequently justifies the PT-CSP system investment. Increasing the degree of dispatchability improves the capacity factor of the PT-CSP system from 21% at 0 h TES to 57% at 18.5 h TES (24 h operation). The capacity factor of the PV system is 18.7% which is mostly similar to PT-CSP with zero dispatchability (0 h TES). The study considers the environmental benefits by estimating the amount of avoided CO 2 emissions, and it was found that increasing the capacity factor augments the environmental benefits.

Summary This work presents an experimental evaluation of a new design of a parabolic trough solar collector (PTC). To maximize the energy yield, a solar tracking system is implemented. The thermal performance of the PTC at three outdoor test methods is evaluated. The new design essentially affects the balloon, the trunk, the insulation, the inner reflector, the glass, the upper plane reflector, and the cover. The system performance with bi‐axial orientation and an absorber with a glass‐covered envelope is compared with two other designs of mono‐ and bi‐axial orientation without a glass‐covered envelope. The tests of the PTC with an aperture area of 2.88 m2 were conducted in Tunisian weather conditions, and the results are compared with similar systems already published data in the literature. A dynamic simulation with TRNSYS software is developed to evaluate the system performance based on experimental results. An economic study to evaluate the system's feasibility is conducted. The results showed that the new design achieved a maximum temperature of 179°C in comparison to 134 and 120°C for the mono‐ and bi‐axial orientation without a glass‐covered envelope, respectively. Furthermore, in the new PTC design, the useful daily energy gain increased by 33% and 15%, and the system thermal efficiency increased by 8.9% and 5.8% in summer and winter, respectively, in comparison to the case of mono‐axial orientation without a glass envelope. Besides, the maximum useful energy gain and the instantaneous thermal efficiency in the new design were 22.6 MJ and 73.45%, respectively, in comparison to 17.93 MJ and 67.41% for the mono‐axial orientation without a glass‐covered envelope. The gross payback period of the system was found to be 3.3 years with an NPV of €5257 over the lifetime of the system.
