Abstract
Systems, methods, techniques and apparatuses of power network state estimation are disclosed. One exemplary embodiment is a method for state estimation in a power network comprising receiving a set of supervisory control and data acquisition (SCADA) information including a power network topology; generating a SCADA state estimation using the set of SCADA information; receiving, with a cloud-computing architecture, a set of PMU phasors; aligning, with the cloud-computing architecture, a timestamp of the SCADA estimation and a timestamp of the set of PMU phasors; updating, with the cloud-computing architecture, the power network topology using the set of PMU phasors; generating, with the cloud-computing architecture, a hybrid state estimation using the updated power network topology, the set of PMU phasors, and the SCADA state estimation; and transmitting the hybrid state estimation to a local control system.
