The penetration level of distributed generation (DG) grows rapidly bringing more frequency fluctuation nowadays. Besides, the power system grows in size day by day; the assumption that the frequencies are the same across the grid is no longer valid. These all bring out problems to the frequency control mechanism currently used. The recently proposed rotor angle control strategy may solve these problems...
Recently, a new strategy that controls generator rotor angle has appeared. The new control strategy can suppress inter-area low-frequency oscillations effectively without the help of any remote signal. It can also improve transient stability. This paper investigates the load balancing mechanism after rotor angle controllers are deployed. Analysis shows that the primary frequency control and automatic...
Since wind power is more versatile and unpredictable than traditional thermal power, increasing wind penetration level generally need more spinning reserve, which is not economical. Frequency related voltage control can be helpful to solve this problem. When frequency become lower due to wind farm decreases its output, voltage can be lowered too to decrease active power absorbed by loads. This method...
