Application of grey system theory to MTPV system optimization

摘要

Combustors are core parts of the Micro-thermo photovoltaic System (MTPV), and their operation process has a significant influence on energy conversion efficiency of the whole system. Introduction of the grey system theory quantifies the tube length and selection point of internal sudden step in the combustor in MTPV system, optimizing the conversion efficiency of the whole system and providing a basis for actual applications in future. In this paper, overall optimization of the MTPV system was achieved by grey forecasting with the GM (1,1) forecasting model, combining with raw data provided by external wall temperature of MgO radiator.
