Intelligent topology‐oriented LS scheme in power systems integrated with high wind power penetration

Load shedding (LS) is one of the most important protection schemes to prevent system blackout. In the case of large disturbances, optimal LS in appropriate buses can effectively maintain the system stability. The higher complexity and lower predictability of modern power systems with high wind power penetration make it difficult to rely on conventional LS schemes, which shed a fixed, predetermined amount of load regardless of disturbance location. This study presents an intelligent LS scheme based on synchrophasor measurements that are adapted to both disturbance size and power system inertia. The proposed scheme utilises improved power flow tracing method to determine the amount and location of load curtailment considering power system constraints. The new method is successfully tested in the IEEE 39‐bus system with high wind power penetration.
