Synchronized Operating Point Stability of Multimachine Power System using Holomorphic Embedding in Kuramoto Framework

The multimachine power system is prone to the possible vulnerabilities caused due to unwanted disturbances that result in the most researched topic of transient stability. The transient stability in the power network is posed as synchronization of the coupled oscillator in the nonuniform second order Kuramoto framework. The conventional stability analysis typically uses the phasor measurement units data that is sensitivity to cyber attacks and iterative power flow solutions which genuinely has convergence issues, that lag reliability, and scalability. To eliminate the dependency of the iterative based load flow methods, a novel approach to adequately investigate the stability of the synchronized operating point in the multimachine power network using holomorphic embedding is presented in this paper. The proposed method is sufficiently illustrated on the IEEE 3-generator 9-bus system along with problem formulation and simulation results.
