Artificial Bee Colony-Based GMPPT for Non-homogeneous Operating Conditions in a Bifacial CPVT System
Demircan, Cihan; Keçebaş, Ali; Bayrakci, Hilmi Cenk (Springer International Publishing Ag, 2020)Photovoltaic (PV) modules directly convert the solar energy into electricity with electrical efficiency in 10-20%. The rest of the incident solar radiation reflects from front surface and converts into thermal energy which ... -
Comparative thermodynamic evaluation of a geothermal power plant by using the advanced exergy and artificial bee colony methods
Özkaraca, Osman; Keçebaş, Ali; Demircan, Cihan (Pergamon-Elsevier Science Ltd, 2018)In this study, the thermodynamic performance of a binary geothermal power plant (GPP) is comparatively evaluated using the exergy analysis and optimization method. Thus, in addition to routes to improve the thermodynamic ... -
