Abstract :
A novel structure-preserving linearized differential and algebraic equations (LDAE) model for small signal eigen-analysis of power system SSO is proposed in this paper. LDAE models of various power system components are formed first. Modularized establishment of entire system model is then conducted quickly according to the network topology. Generalized eigenvalue & eigenvector calculation, and eigenvalue sensitivity analysis based on the LDAE model are applied thereafter. The effectiveness of the proposed LDAE model based SSO analysis approach is verified through computer test results. The LDAE-based SSO study model and the corresponding generalized eigen-analysis approach pave the way for power system SSO study with HVDC transmission and/or FACTS devices without eliminating any algebraic variables.
