The lowest initial voltage magnitude is 0.9902 at bus DEMAR69. To quickly determine the lowest per-unit voltage magnitude, left-click on the PU Volt column header to sort the column (clicking a second time reverses the sort).
Use Tools, Play to animate the one-line and Tools, Pause to stop the animation.Determine the lowest per-unit voltage and the maximum line/transformer loading both for the initial case and for the case with the line from bus TIM69 to HANNAH69 out of service.SOLUTIONUse single solution to initially solve the power flow, and then Case Information, Network, Buses… to view a listing of all the buses in the case. The one-line can be panned by pressing the arrow keys, and it can be zoomed by pressing the hctrli with the up arrow key to zoom in or with the down arrow key to zoom out. This case models a 37-bus, 9-generator power system containing three different voltage levels (345 kV, 138 kV, and 69 kV) with 57 transmission lines or transformers.

Note, because of solution convergence tolerances the manually calculated results may not exactly match the OFP calculated bus LMPs.EXAMPLE 1 Power-flow program: 37-bus systemTo see a power-flow example of a larger system, open PowerWorld Simulator case in this Example(see Figure 1). Verify the LMP at the UIUC69 bus by manually changing the load at the bus by one MW, and then noting the change in the Total Cost field. Then Select LP OPF, Primal LP to solve the case using the OPF, and again view the bus LMPs. Before solving the case, select LP OPF, OFP Buses to view the bus LMPs, noting that they are all identical. When the case is loaded the “Total Cost” field shows the economic dispatch solution, which results in an overload on the remaining line between buses BLT69 and UIUC69.

This case models a slightly modified version of the 37 bus case from Example 1 with generator cost information, but also with two of the three lines between buses BLT69 and UIUC69 open. This problem has been solved: Solutions for Chapter 12 Problem 29P: Load PowerWorld Simulator case Problem 12_30.
