Using the following bus and line data, find the following:(a) The scheduled power at each bus. This is Pk(s) and Qk(s) in your textbook.(b) The power injections at each bus. This is Pk(x) and Qk(x) in your textbook.(c) The power mismatch vector(d) How does the presence of a PV bus change your problem setup?(e) The Jacobian matrix with the initial values plugged in. How many columns should ithave?(f) Put together the parts from (c) and (d) into the Ax = b matrix form. What is the significance of thex vector that you will solve in the Newton-Raphson power flow method?
