Summary: | When there is a large power imbalance, the frequency of the power system will be declined lower than the allowable value. Therefore, maintaining the frequency within the allowable value is essential. In the case of an emergency control such as a large generator trip, an effective load shedding plan is required to avoid frequency dropping and blackout. This paper introduces a new method for determining the location of the load shedding by using the phase angle sensitivity of two buses. Load shedding is based on the calculation sensitivity from the loads to the generator outage location. The shorter the loads have sensitivity; the larger capacity loads will shed. Experiment results showed the amount of load shedding is lower, the recovery time of frequency and rotor angle are faster than the conventional load shedding. |
