“…It is observed that the designed PSDS system for Jamshoro has good solar potential with a net system efficiency of 23.39% and LCOE of 0.13 $/kWh. Bataineh and Taamneh 23 reported the minimum value of LCOE (0.115 $/kWh). The low value of LCOE is that the Maan city of Jordan has a high value of direct solar irradiance (2700 kWh/m 2 /y).…”

“…The results showed that the yearly average electrical power production was enhanced due to the technical and economic parameters and obtained the value of 12.68 GWh. Bataineh and Taamneh 23 used the SAM software, developed at National Renewable Energy Laboratory (NREL), 24 to model techno‐economic aspects for easy decision‐making in an area of renewable energy. The simulation was carried out for the solar dish system to electrify the isolated villages in Maan, Jordan.…”

Summary In this study, a stand‐alone parabolic solar dish/Stirling (PSDS) system model is developed and investigated. The techno‐enviro‐economic performance of a 25‐kW stand‐alone PSDS system is simulated in the System Advisor Model (SAM) tool under ambient conditions of Jamshoro, Pakistan. The avoided CO2 emissions due to the installation of the proposed system are calculated in an Excel spreadsheet. The methodology for emissions calculation is based on the average value of emissions per kWh recommended by the Intergovernmental Panel on Climate Change (IPCC). The results indicate that the proposed PSDS system generates 38.6 MWh of electrical energy annually, and the maximum energy of 3.38 MWh is achieved in January. The main reason for that is the highest value of DNI in that month. The system has attained a net efficiency of 23.39% and a levelized cost of energy (LCOE) of 0.13 $/kWh. The yearly emissions from PSDS are 762 kg, which is only 2.2% and 4.69% of coal and natural gas, respectively. Moreover, the sensitivity analysis of the PSDS system showed that the projected mirror area and collector cost affects the power output and cost of generation significantly.

Summary The intensity of the solar radiations falling on the earth surface ranges between 5 and 7.5 kWh/m2/day. For the non‐directed solar thermal application, higher intensity level is required. The Concentrating Solar Power (CSP) technology incorporating reflecting mirrors reinforces the solar radiations with high intensity. It is suitable for various applications; that is, space heating, space cooling, and cooking, steam, and power generation without any polluted emissions. Meanwhile, among the various CSP technologies, the Concentrating Solar Parabolic Dish Stirling engine System (CSP‐DSS) has got attention of the research community due to its various attractive features. The output power and efficiency of the CSP‐DSS depend upon their geometrical, optical, and operating parameters. It is therefore, necessary to mathematically investigate the influence of these parameters on system performance before its design and installation. In the existing literature reported, only some specific parameters of the CSP‐DSS have been focused and considered to investigate the system performance. To the best of author's knowledge, no literature has been found to provide the mathematical modeling of all the system parameters in a single manuscript to study and investigate their influence on the system performance. Hence, this review article aims to compile, expansively review and organize the systematical mathematical modeling for all optical, geometrical, and operating parameters of the CSP‐DSS along with the system design methodology. Likewise, the effects of these parameters on the system output power and efficiency under various operating conditions have been investigated. In addition, comprehensive study of CSP‐DSS components along with their classification have been painstakingly discussed to determine optimal system configuration. Finally, the latest review study in the field of CSP‐DSS have been deeply and comprehensively discussed. This review study concludes that, the kinematic gamma type Stirling engine coupled with Permanent Magnet DC generator (PMDC) and Azimuth‐Altitude Dual Axis Tracker (AADAT) could be the better CSP‐DSS design and configuration in context of the standalone off‐grid electricity generation system.

“…It can operate as an engine or as a cooler by reversing the thermodynamic cycle. Since 1816, several developments led to applications in various fields such as solar converters of combined heat and power [4][5][6] for example. Whereas numerous works deal with Stirling engines at a macroscopic scale [7], only a few works concern miniaturized Stirling engines.…”

In this paper, we present a new model and design of a MEMS Stirling machine. The concept could be used to provide electricity to low level power systems. A modified adiabatic model including losses of a Stirling engine such as regenerator thermal efficiency, wall conduction, pressure drop, hysteresis, membrane finite speed and squeeze film damping losses is presented. A base design machine is proposed. A parametric study is conducted and used to derive guidelines for miniature design. Compared to macro-scale design, the same trend was observed for the influence of the thermal performance regenerator. However, different trends from macroscopic engines were observed: conduction losses are of major importance due to the low power of the miniature engines, hysteresis losses in the bounce space are also of high amplitude due to the small size if this volume, the choice of the working gas leads to hydrogen or air and not helium. We computed that membrane finite speed losses and squeeze film damping losses can be neglected in the investigated machine size. The first part of the paper presents the micromachine specific features, the second part describes the model, the last part presents the base design results and design guidelines.
