The Impact

Malaysia receives an annual average of 2200 hours of solar radiation, making her abundant renewable resources to generate electricity. Thus, a good planning is required to manage the resources efficiently and to utilize the abundant resources fully. Concentrating solar power (CSP) technology is a possible approach to manage renewable resources in Malaysia. Using a techno-economic analysis, the researchers, engineers, industries, or government agencies will be able to identify contributing and discouraging factors of building the CSP technology. This paper presents a techno-economic analysis of two CSP technology: parabolic trough collector (PTC) and solar power tower (SPT), for potential implementation in Malaysia. This paper provides information on two CSP technologies to researchers and industries prior to the planning and design stages. The techno-economic analysis begins with identifying potential locations based on the direct normal irradiation (DNI). Kuah, Kuantan, Miri and Labuan are identified as the potential locations using the RETScreen Expert software. Labuan could be the most promising PTC and SPT technology project because it has the highest DNI received annually. Next, the techno-economic analysis uses two reference projects, ANDASOL-1 and PS-10 systems in Spain, as references for all locations. The techno-economic analysis consists of annual electricity generation, unit cost of electricity, net Present Value (NPV), benefit-to-cost ratio (B/C), internal rate of return (IRR), and payback period calculated in Microsoft Excel. Finally, a sensitivity analysis is conducted to measure the impact of uncertainties of one or more input variables, leading to uncertainties on the output variables. Two sensitive factors are the annual electricity generation and the initial cost, affecting the construction, installation, and implementation of PTC or SPT technology.

Parabolic trough collector (PTC) is one of the most widespread solar concentration technologies and represents the biggest share of the CSP market; it is currently used in various applications, such as electricity generation, heat production for industrial processes, water desalination in arid regions and industrial cooling. The current paper provides a synopsis of the commonly used sun trackers and investigates the impact of various sun tracking modes on thermal performance of a parabolic trough collector. Two sun-tracking configurations, full automatic and semi-automatic, and a stationary one have numerically been investigated. The simulation results have shown that, under the system conditions (design, operating and weather), the PTC's performance depends strongly on the kind of sun tracking technique and on how this technique is exploited. Furthermore, the current study has proven that there are some optimal semi-automatic configurations that are more efficient than one-axis sun tracking systems. The comparison of the mathematical model used in this paper with the thermal profile of some experimental data available in the literature has shown a good agreement with a remarkably low relative error (2.93%).

Parabolic trough solar technology is the most proven and lowest cost large-scale solar power technology available today, primarily because of the nine large commercial-scale solar power plants that are operating in the California Mojave Desert. However, no new plants have been built during the past ten years because the cost of power from these plants is more expensive than power from conventional fossil fuel power plants. This paper reviews the current cost of energy and the potential for reducing the cost of energy from parabolic trough solar power plant technology based on the latest technological advancements and projected improvements from industry and sponsored R&D. The paper also looks at the impact of project financing and incentives on the cost of energy.

This paper presents the simulation and modeling of the concentrated solar power (CSP) plant for multipurpose applications at Borg El Arab in Egypt. The plant produces 1 MWe and 250 m3 of distilled water using steam turbine and electric generator. The purpose of using different applications is to improve the overall efficiency and the coefficient of performance of the plant. The trnsys simulation platform was used for simulating the thermal performance of the solar power and desalination plant covering the parabolic trough concentrator (PTC), storage tank with an integrated steam generator, a backup unit, steam turbine, electric generator, and two effects desalination unit. The temperature and energy profiles of the plant were investigated for the PTC, steam generator and the electric generator. The results prove that the simulation could be used to support the operation of the CSP plant and for improving the performance of the cogeneration plant at Borg El Arab.
