| Abstract: | The theory of forced power oscillation in the power system can be regarded as power oscillation of non-neg- ative damping in power system. The paper simulated and analyzed transmitting power oscillation induced by superpo- sition of wind disturbance and load power random fluctuation when wind farm （which consists of 3 different wind tur- bines） switching in power grid. The simulation results showed that, the fluctuation from different wind turbines caused different system transmitting power oscillation. When ramp wind or stochastic wind added load fluctuation separately, it caused the highest power oscillation amplitude, and led to a large change of the power plant output in the region, which brought huge influence on the safe and stable operation of power grid. |
| Keywords: | Xinjiang power grid wind farm access point low frequency oscillation forced power oscillation |
