Project -
You should submit a report for each project that explains the following:
1. What is the program about?
2. Why is that important?
3. Description of the test system
4. Answer the "questions for the report" (slide 8)
5. Appendix with the MATLAB code - You are not allowed to use symbolic math (e.g. jacobian.m).
Implement a power flow program in MATLAB using the Newton-Raphson algorithm.
The program must have the following features:
- Be able to represent any type of bus (i.e. Slack, PQ and PV)
- Represent transmission elements (π model)
- Include shunt elements (e.g. shunt inductance, shunt capacitance, etc.)
- Display in the MATLAB command window the following:
1. the Ybus matrix of the system
2. the Jacobian of the system for any iteration
3. the mismatches for any iteration
4. the nodal voltage magnitudes and angles for each iteration
- Use a text editor for your report (e.g. Word, LaTeX)
- Submit your source code ("file.m") via dropbox.
Questions for the report -
1) Report the Jacobian of the 2nd and 3rd iterations for system A.
2) Report element (3,3) of the Jacobian for the 2nd and 3rd iteration for syst. B
3) Compute the Jacobian for the first iteration, and continue all the iterations without updating it. Does the problem converges? Explain why?
4) Plot of the voltage magnitudes and angles as a function of the bus number for the first and last iterations of both systems.
5) Report the power flowing from bus 3 to 4 in test system A, and explain the reasons of such active and reactive flows.
6) Same as before but for buses 6 and 11 for test system B.
7) Which is the bus with the lowest voltage magnitude in system A, and which one in system B?
8) What could you do to increase the voltage at that bus? Show the effect of your proposed solution numerically (i.e. run the power flow with your proposed solution).
9) Compute the DC solution for both systems and use the resulting angles as starting point for the NR method. What happens to the convergence? Why?
