Co-Simulation Stability in Power Systems
This study focuses on dynamic modeling in power system co-simulation and aims to develop a state space mathematical model to evaluate the impact of phasor extraction, communication methods and system equivalent impedance on co-simulation stability. A 2-bus test power system with RLC load and a continuous-time pi model transmission line is used to validate the developed methodology. The results highlight the importance of a robust interface bar in enhancing stability and caution against extreme power values that can induce instability in simulation process. Overall, this work contributes to the study of the stability of power system co-simulation, considering different phasor extraction methods, communication protocols and complex systems, thus advancing the research and development of co-simulation technology.
