In your EE523 activity booklet (Yellow booklet), present a clear and orderly handwritten solution for the problem
below.
Compute up to 4 decimal places.
Show all the steps in the solution. No shortcuts allowed.
Solutions must be in
accordance with the method of solution in C7 of Stevenson.
All answers for Zbus, Ybus, other passive elements must be
in rectangular form while answers for voltage, currents, and power must be expressed in rectangular and polar form.
Box all final answers.
Unboxed final answers will not be considered.
In the first few pages of the homework, present the
summary of the final answers in all of the items (without solution), followed by the orderly, clear, and complete solution
for each item.
Submit the whole homework on or before January 30 inside the EE office.
A homework that is
INCOMPLETE and/or that is submitted after the deadline will NOT be accepted
