Modeling Platform for a Micro-CHP System with SOFC Operating under Load Changes

Article Preview

Abstract:

Paper presents a novel approach to modeling of a micro-combined heat and power (μ-CHP) unit with solid oxide fuel cells (SOFC). The proposed numerical simulator can be applied both to the analysis of a system operation in the design point and in off-design. Main components of the power system have been represented by dedicated sub-models, incorporated in the numerical simulator of a complete μ-CHP unit. The proposed modeling platform offers the possibility of analyzing system with different solid oxide fuel cells, its operation at partial loads and with various fuels. Components of the system can be modified, technical specifications can be adjusted in order to allow simulation of other components. The main equations for electrical and overall efficiency calculations are given and discussed.
