A Comparative Analysis of a Power System Stability with Virtual Inertia

The paper investigates the stability of a power system with synchronverters. A synchronverter is control strategy for voltage source converters that introduces virtual inertia by mimicking synchronous machines. authors picked commonly known IEEE 9 bus and 39 test case systems studies. presents system’s modal analysis Voltage Source Converters (VSCs) controlled as synchronverters, vector control, or Rate Change Frequency-based Virtual Synchronous Generator, thus comparing different approaches to VSC control. first study compares selected algorithms, system, one in paper. results demonstrate benefits synchronverters over other strategies. has higher minimal damping ratio, which proven be numerical simulations. In second study, effects placement were investigated. computations showed indeed important, however, important. Besides, exhibits better characteristics. demonstrates application feasible can meet demand algorithms bring inertia.
