Design of a Small Renewable Resource Model based on the Stirling Engine with Alpha and Beta Configurations

Abstract

<p>This paper presents the conceptual design of Stirling engine based Alpha and Beta configurations. The performances of Stirling engine based Beta configuration will be expounded elaborately in the discussion. The Stirling engines are durable in its operation that requires less maintenance cost. The methodology for both configurations consists of thermodynamic formulation of Stirling Cycle, Schmidt theory and few composition of flywheel and Ross-Yoke dimension. Customarily, the Stirling engine based Beta configuration will operate during the occurrence of low and high temperature differences emanating from any type of waste heat energy. A straightforward analysis on the performance of Stirling engine based Beta configuration has been performed corresponding to the temperature variation of cooling agent. The results have shown that the temperature variation of cooling agent has a direct effect on the performances of Stirling engine in terms of its speed, voltage and output power. </p>

Performance comparison of artificial intelligence techniques in short term current forecasting for photovoltaic system

“…The growing capacity for global solar PV sector already reached 178GW in 2014, and estimated to reach 540GW in 2019 [1,2]. In recent years, solar PV system has been developed drastically and the reason behind it is because of the nature usage of PV that is maintenance free, long lasting used, and environmentally friendly [3][4][5][6][7][8]. However, PV system is operating in a non-stationary random process caused by the variability of solar irradiance and other environmental factors that may affect the output current.…”
