|Title:||DATA COST EFFECTIVE FAST SIMILARITY SEARCH WITH PRIORITY ACCESS|
Example implementations described herein are directed to detecting similarity between anomalous events that are currently occurring or have previously occurred transmission power system based on phasor management unit (PMU) data to provide information to grid operators with online decision support. From the high-resolution time synchronized PMU data, the events can be quickly retrieved and compared so that operators can be provided with remedy actions that were attempted in response to the previous events. Utilization of PMU information for such decision support may compliment operation practices relying on supervisory control and data acquisition (SCADA) measurements by allowing a much fast response to the currently occurring event. Accurate identification of similar, historical events can advise grid operators of the cause of disturbances and provide ideas for response. Implementations of the proposed technology may improve the resilience and reliability of the transmission power systems.
