Research of experimental hybrid energy complex with fuel cells operating on biogas

Abstract

The article deals with the development of a hybrid energy complex (HEC) based on solid oxide fuel cells (SOFC) operating on biogas. Low maneuverability of SOFC prevents a widespread use of such power installations in consumers’ power supply systems. The authors have developed the design of the HEC and an active-adaptive control system that allows solving the problem of SOFC low maneuverability. An experimental HEC consisting of a SOFC generation system, an accumulation system, a coupling system and a control system have been created. The research of the experimental HEC characteristics and the possibility of developing emergency situations during its operation has been carried out. The results of the charge and discharge characteristics of the accumulation system research, as well as the current and voltage dependences of the HEC coupling system are presented. The conducted studies have proved the effectiveness of the developed scientific and technical innovations.
