Modeling, Control and Optimization of a Small Scale CHP System in Island operating Mode based on Fuzzy logic controller
Abstract
This paper presents the modeling, control
scheme and optimization of a small scale combined heat and
power (SSCHP) in island operating mode. A thermo dynamic
model is carried out for SSCHP engine using Carnot machine
method, while an optimization technique is formulated to
identify CHP engine parameters. In addition, a dynamic model is
built based on a system identification toolbox for SSCHP engine
to study the dynamic behavior of the SSCHP during operating
mode. In island mode, the Fuzzy logic controller (FLC) is used
to regulate the inputs of SSCHP, and to match electric load
demand. The complete system was represented and simulated in
Matlab/Simulink.
