Sensitivity analysis for the IEEE 30 bus system using load-flow studies

Load flow analysis is the backbone of the power system studies and design, and through it the voltage magnitude and phase angle at each bus and the complex power flowing in each transmission line can be obtained. In this paper, we use the load-flow to perform a sensitivity analysis of the IEEE 30 bus system. We find the maximum complex power flowing in each transmission line in case of no fault and in case of a single transmission line fault in the steady state condition. The results of this analysis helps identify the most critical lines in the system, which can help better plan the capacities of such lines, and minimize the probability of potential cascading failures.
