Sensitivity analysis of interconnected power system low frequency oscillation
نویسندگان
چکیده
The damping sensitivity analysis of interconnected power system low frequency oscillation is studied. The function of sensitivity analysis is implemented in the Small Signal Stability Analysis Package (SSAP). The paper mainly analyzes the sensitivities of oscillation modes with respect to the parameters of power system stabilizer (PSS) in the excitation systems of generators for a physical large-scale interconnected power system with AC/DC parallel transmission – China Southern Power Grid (CSG). The results show the effectiveness of this function which could direct the optimization of PSS parameters and improve the low frequency oscillation damping of the system. Key-Words: Power system, Low frequency oscillation, Eigenvalue sensitivity, Power system stabilizer, Parameter optimization
