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