This paper presents a novel estimation scheme for
power grids based on distributed observers. Assuming only the
generator voltage phase angles are measured and the electrical
load active power demands are specified, we design an observer
for each bus of the power grid, exploiting only knowledge of
local information about the power system. In particular, we
propose a super-twisting-like sliding mode observer to estimate
the frequency deviation for each generator bus, and a so-called
algebraic observer to estimate the load voltage phase angle for
each load bus based on distributed iterative algorithms. The
observer-based estimation scheme is validated by considering the
IEEE 39 bus SimPowerSystems model.
