Study on a CHP plant using SOFC-ICE integrated system: Analysis, modeling and control Zhiyao Xu, Shen Cheng, Jian Zhang, Jinwu Gao

Abstract

Combined heat and power (CHP) system has been demonstrated to be an efficient cogeneration energy system. With the development of fuel cell technology, one kind of electrochemical-combustion CHP system, such as SOFC-GT, SOFC-ICE, was studied in the past decades. However, how to optimize the system efficiency, maximize the flexibility of system are not clear yet. Aiming to improve fuel efficiency, this research studies controller design of this system using operation point optimization theory for electricity generation, and the performances are validated by simulation.

Keywords CHP, SOFC-ICE, transient dynamics, operation point optimization, simulation
