Regarding state estimation in electrical power grid, does the voltage phasor magnitude at each bus(P-Q bus and P-V bus) considered as a static state variable or a dynamic state? I am a little bit confused about it.
If we consider those bus voltages as static state, can we use dynamic state estimation techniques to get an estimation of those voltage or we only use static state estimation?.
If I want to plot the magnitude and phase angle at each bus over time, are there network dynamic models I can use to do so? For example a differential equation of the voltage with parameters such as reactive, real power etc...
(I am working on a summer project on state estimation using phasor measurement units -PMU-)
