Refering to the paper: "Adaptative Adjustment of Noise Covariance in Kalman Filter for DSE". In the paper, the autors state that PST is used to generate simulation data. I would like to know how do you insert process and measurement noise to the simulation data?
I understand that 4.0% noise is added to the current and voltage phasors, and to Efd and Tm. This would be the measurement noise? When does the process noise is added to the simulation data?
I would be very thankfull for your help.
Dear Ninazunta,
Sorry about my delay.
As you understood, the measurement noise is added to the voltage, current, Efd and Tm.
The process noise is added to equation 6.b, in the above mentioned paper, at each step of Kalman filter. Also you can calculate the Q using Qk= 0.04 max(abs(diff(x(1:N)))).
If you have any questions please contact me.
Best Regards,
Shahrokh
