Hi everyone

When I am simulating the IEEE9bus system. After the system runs stably for 10 seconds. I increase the load of 10MW on Bus5, and then perform dynamic simulation, the frequency will oscillate more and more, where can I find the reason?! http:// (image description)

Try incrementally reducing the load step size to get a better understanding of what's driving the instability.
