Comprehensive modeling and stability analysis of biomass generation

Biomass is one of the renewable energy sources being used widely for power generation. This paper presents an effort to develop a comprehensive model for a biomass based generation system. The research objectives include mathematical modeling, stability studies, and sensitivity analysis using MATLAB/Simulink. A mathematical model for the gas turbine has been developed and transient stability has been carried out for small test case system. Maximum rotor speed deviation, oscillation duration, rotor angle, and mechanical power have been taken as stability indicators in this study. Additionally, the sensitivity of the system to the changes of gas turbine parameters has been investigated under balanced and unbalanced fault scenarios.
