The goal of the state estimation (SE) algorithm is to estimate complex bus
voltages as state variables based on the available set of measurements in the
power system. Because phasor measurement units (PMUs) are increasingly being
used in transmission power systems, there is a need for a fast SE solver that
can take advantage of PMU high sampling rates. This paper proposes training a
graph neural network (GNN) to learn the estimates given the PMU voltage and
current measurements as inputs, with the intent of obtaining fast and accurate
predictions …
