Comparison of rotor angle curve before and after collaborative transient stability control on fault lines 26−29 of IEEE 39 bus system. Figures 7 and 8 show the voltage curves before and after collaborative control of the IEEE 39 bus system under single-phase short circuit fault of the line (bus 25 to bus 26; bus 26 to bus 29); the test system is unstable since the collaborative transient stability control is not carried out. However, the system changed to stable after the collaborative control. The voltage curves further validate the effectiveness of the proposed collaborative transient stability

Aiming at the influence of wind power and load uncertainty on the transient stability of a power system under low carbon mode, this paper first proposes a collaborative preventive and emergency control model of transient stability by distribution preserving graph representation learning (DPG). Second, the uncertainty set of wind power output and lo...

With access to distributed power generation and interconnection between regions, China’s power system structure is becoming increasingly complex, and the requirements for power grid dispatching capacity are getting higher and higher. When the power grid fails, a large amount of alarm information appears in the monitoring window, which needs to be p...
