Link fuzzy logic with matpower

2018-03-07 Thread Charalambos Ioannou
Hello Friends, I am interested if it is possible to link together fuzzy logic with matpower or model predictive control with matpower?? Anyone knows or done it? Thanks in advance. Kind Regards, Charalampos Get Outlook for Android

AC OPF Convergence Issue

2018-03-07 Thread Aakanksha Dubey
Hi All, I am developing a model for transmission grid at Lehigh Valley. My model seems to converge for DC OPF but is unable to converge for AC. I have tried the following to make it converge but nothing works: - Relaxed Vmax, Vmix, BR_R, Rate_A,Rate_B,Rate_C - Checked the tap ratio, Qmax,

Hi, I would recommend you to go through these 8 steps (Incremental approach) suggested by Jose L. Marin. Click the link given below and follow the steps. When I was working with the German Grid I had same problems but these steps really worked out in my case. I hope you will get solution. *https:

The voltage magnitudes in MATPOWER data files, (bus(:,VM)), are given in per unit and are generally close to 1.0. You have very low voltages for many of the buses. Similarly, the VMAX and VMIN values are also in per unit and generally they are 1.0 and 0.95, respectively. The following code resul

Thank You, Mirish and Shri for the guidance. Shri, the model is converging now. I understand that Vmax and Vmin limits should have been more relaxed. I have a couple of quick follow-up questions: - I had set the voltage magnitudes on per unit basis since the network voltages range from 69kV
