Electromechanical Wave Propagation Modeling for Dynamic Stability Analysis in Power Systems

Accurate dynamic modeling of power systems is essential to assess the stability of electrical power systems when faced with disturbances, which can trigger cascading failures leading to blackouts. A continuum model proves to be effective in capturing Electromechanical Wave (EMW) propagation characteristics, including its velocity, arrival time, and deviations. Analyzing these characteristics enables the assessment of the impacts of EMW on the performance of the protection system.

Prior research has often modeled nonlinear EMW propagation through Partial Differential Equations (PDEs) within a homogeneous and uniform frame structure, assuming constant bus voltages across the entire power system. However, this assumption can produce inaccurate results. In this presentation, this assumption is relaxed by introducing a second-order nonlinear hyperbolic EMW propagation equation model that accounts for voltage variations. Additionally, numerical solutions for the EMW propagation equation are presented using the Lax-Wendroff integration method. To validate the proposed approach, simulations are conducted on several test systems. The simulation results demonstrate the effectiveness of the proposed model and emphasize the importance of including the bus voltage equations in the analysis.
