3. Choose one of the methods: Newton-Raphson method or fast decouple method to solve the power flow problem. Please copy paste your codes in your HW report. Put a box for the iteration procedure.

Q4. Please present the following:

  • Plot the error versus iteration (use semilogy function).
  • Present a table of voltage phasors at each bus.
  • Compute the total power loss in the system.

Q5. Please adjust the generator dispatch pattern and re-compute the system power loss. Show that the power loss can be reduced. Present a table to compare the original case and your constructed case in terms of generator dispatch pattern and power loss.
