Stability analysis of power systems using network decomposition and local gain analysis

Abstract:

We introduce a method for analyzing large-scale power systems by decomposing them into coupled lower order subsystems. This reduces the computational complexity of the analysis and enables us to scale the Sum of Squares programming framework for nonlinear system analysis. The method constructs subsystem Lyapunov functions which are used to estimate the region of attraction pertaining to the equilibrium point of each isolated subsystem. Then a disturbance analysis framework uses the level sets...
