“…In India, there is the lack of infrastructural development; investors are therefore required to spend a lot of research and time to locate the potential sites for the construction of CSP plants [1]. Another challenge is that after identifying the potential sites, investors require approval from various authorities in order to develop CSP technologies [11,13,80,86]. To address this matter, the government needs to support the entire project implementation, including the allocation of potential sites, funds, transportation facilities, water resources, and other development measures required for the infrastructure.…”

“…A number of studies have been carried out globally concerning techno-economic assessments of potential CSP systems. For instance, Tahir et al [13] evaluated the potential, viability, policy framework, and potential barriers of CSP generation in Pakistan. The study concluded that regions such as Pishin and Quetta are favorable for the CSP generation.…”

“…This is important since India is vast with different weather conditions, and hence a study at a particular location cannot be used to predict the performance of such systems across the country. Therefore, in this present study, we examined the techno-economic feasibility of a CSP based on STPP for six different locations in India in order to fill this current research gap, which is useful for research directions and policy interventions [13,15]. According to Aly et al [27], a dry-cooled CSP plant is modelled at sites far away from a water source, while a water-cooled CSP plant is modelled at sites near water resources.…”

India is endowed with a lot of solar radiation as a result of its location. The Indian government therefore intends to maximize the usage of its solar energy resources through the development of solar power plants across the country. The concentrated solar power plant (CSP) is one of the technologies that rely on solar energy for its electricity generation. The type of condenser model in the CSP technology has the potential to affect its techno-economic viability. In this paper, a 100 MW solar tower power plant (STPP) with two different condenser models, i.e., the dry-cooled STPP and wet-cooled STPP models, are studied using the System Advisor Model (SAM) at six different geographical areas in India. The study employed the optimization of the thermal energy storage and the solar field size to identify the minimum levelized cost of electricity (LCOE) for all six locations. Results from the simulation show that the LCOE will range between 13 and 17 cents/kWh under the optimization conditions for the STPP dry-cooled condenser model, while that of the wet-cooled condenser model will range between 12.40 and 12.96 USD cents/kWh for the study locations. It was also observed that the optimized solar multiple (SM) for the dry-cooled STPP model ranges between 1.4 and 1.8, whereas that of the wet-cooled model ranges between 1 and 1.8. The study identified Bhopal as the best location for installing the STPP plant for both condenser models. In addition, this paper also discusses major potential barriers and government policies that are needed to develop CSP technologies in India. The outcome of the study is expected to help both government and other stakeholders in decision making and policy formulation for the sector.

The study aims to improve the performance of the thermal power generation system in power plants by analyzing its working principle. The thermal power generation system of large power plants is taken as the research object. The Fluent software is used for simulation experiments. A new optimization method of the rotor structure in the electronic heat absorption equipment and heat exchange pipeline is proposed. By improving the rotor, the heat transfer efficiency of the heat exchange pipeline is greatly improved. Through the relevant research on the thermal power generation system, the rotor's heat transfer performance of the exchange tube is analyzed based on the strong heat transfer convection mechanism. Then the simulation experiment is carried out. Based on the heat transfer mechanism of the combined rotor in the tube path unit, the heat transfer pipe is optimized. The numerical simulation results of rotor heat transfer and fluid flow show that the average resource utilization rate increases with time. The average resource utilization efficiency of the system reaches more than 70% in 45 ms. When the pipe size is 100 mm, the performance of the resistance coefficient is 3.6 before improvement and 2.8 after improvement. When iteration times are 200, the rotor heat transfer of four kinds of pipes reaches the maximum, and the rotor heat transfer of No. 1 pipe with the size of 22 mm can reach 10000W. The research demonstrates the superiority of the proposed heat exchange tube, which provides a theoretical reference for optimizing the heat transfer tube and the efficiency of the thermal power generation system.

Clean and sustainable renewable energy resources provide a feasible solution for electrical power generation nowadays. This encourages many countries around the world to increase their renewable energy share. In a reference case, Egypt aims at increasing its renewable energy share in electricity generation from 9% in 2014 to 25% in 2030. [1] High rates of solar energy are available most of the year in Egypt. According to the solar atlas of Egypt, [2] the annual averaged direct normal irradiance (DNI) in Egypt is 292 W m À2 while the monthly averaged maximum DNI reaches 450 W m À2 . Moreover, Egypt has 2554 and 2208 kWh m À2 of available solar energy for concentrated solar power (CSP) and photovoltaic (PV), [2] respectively. Therefore, both the CSP and PV technologies are implemented in Egypt. While PV is cheaper than CSP, the latter is fully dispatchable. [3] Moreover, a PV with storage batteries is more expensive than a CSP with thermal energy storage (TES). [3] Therefore, recent investigations show that CSP and PV are complementary technologies rather than competitive ones. [3][4][5] However, Egypt has not integrated CSP and PV technologies in commercial power plants so far. CSP is a good choice for Egypt due to the high DNI and the hot climate conditions. Accordingly, Egypt has constructed a CSP plant in Kuraymat (100 km south of Cairo). The solar field in Kuraymat implements parabolic trough collectors (PTCs) with a total field aperture area of 130 800 m 2 . [6] Figure 1 shows the main components of the parabolic trough collector (PTC). A parabolic-shaped reflector collects the sun's rays and reflects them through a glass tube onto a receiver tube. The receiver tube absorbs the incident and reflected solar radiation and utilizes this energy to increase the temperature of a heat transfer fluid (HTF) that flows inside the receiver tube. The levelized cost of energy (LCOE) is one of the most significant parameters that indicate the feasibility of an electrical power generation technology. It is always desired to reduce the LCOE of every power generation technology to make it commercially competitive. Reducing the LCOE of the CSP plants with PTC technology can be attained by increasing the overall thermal efficiency while reducing the capital and running costs. El Hamdani et al. [7] estimated the impact of the DNI, solar multiple, mirrors efficiency, cycle efficiency, and absorber efficiency on the reduction of the LCOE of a 1MWe parabolic trough plant at different sites in Morocco. Aseri et al. [8] investigated the possibility of reducing the high capital cost of PTCs. They attained a 29.9% reduction in capital cost by implementing large aperture area PTCs with molten salt as both HTF and storage medium. Lopes et al. [9] showed a 6.3% reduction in LCOE when applying the HitecXL molten salt in a 50 MWe/7.5 h-of-storage power plant. They simulated the plant performance using NREL's System Advisor Model (SAM) software. [10] Tahir et al. [11] estimated the minimum LCOE for a 100 MW PTC power plant in six different ...
