Transient Stability of Power Systems Integrated With Inverter-Based Generation

The fundamental mechanism of transient stability the conventional power system can be physically understood with rotor swing dynamics synchronous generators (SGs). basic factor affecting is power-angle relationship among SGs. integration a large number inverter-based generations (IBGs) into inevitably changes original relationship, therefore leading to more complicated mechanism. In this letter, impact IBG on analytically investigated. It shown that connection nonsinusoidal curve, introduces limit peak swing, and brings about new bottleneck for stability.
