Georgia Tech Team: Distributed Dynamic State Estimation (DDSE)
Team Leader: Athanasios P. Meliopoulos
Team Member: George J. Cokkinides
DDSE uses a distributed approach for data acquisition, protection & control of an active distribution system (ADS). An Active Districbution System (ADS) is partitioned into nodes, each node performs Dynamic State Estimation (DSE) using all available measurements at this node from Merging Units, PMUs, relays and meters. The estimated state of each node is send to the substation where all the SE results are combined to provide the state estimate of the entire distribution system. Several tests are performed to verify accuracy of the solution.
The DDSE detects any anomalies in data and in this case, via hypothesis testing, pinpoints the source of the anomalies. This way it detects hidden failures, calibration errors and cyber attacks. Many of these anomalies can be healed via software until a technician can remove the source.
