“…The methodology used the OPF-AC constraints as a basis. The methodology was applied to the IEEE 39 bus-bar test system, and based on the proposed methodology, the two worst conditions that could occur in the system were identified; based on this, the decision to reinforce the system was made, for this EPS, TL [16][17][18][19] Since the proposed methodology is based on the value of the contingency index J, it was necessary to compare the value of J in the initial state of the EPS (J = 23.08555) and thus identify the worst contingencies, which were the contingency in TL 16-19 in which J = 26.976034 and the contingency in TL 21-22 in which J = 25.2405899; as can be seen, there was a growth in the J index, and this is due to the degradation of some of the electrical parameters that were quantified to calculate J.…”

“…To find a solution to the problem of TEP, Ref. [17] proposes the improved genetic algorithm; it is an evolutionary meta-heuristic that solves the TEP through heuristic performance and is related to the power flow of the transmission system through sensitivity indices, obtaining a remedial tool. This results in system expansion with various size and topology characteristics.…”

“…Base case: By performing the optimal expansion of the EPS, running an OPF-AC without contingencies, and comparing it with the Base Case EPS, it is determined that voltage improves in bars 21,16,24,15,17,18 Similarly, in Figure 4, the behavior of the voltage angle in each node of the EPS is analyzed. It is known from previous studies that when a contingency occurs, the voltage degrades, and sometimes, it can even reach states of angle instability; therefore, it is necessary to improve the power systems [32].…”

This paper analyzes the behavior of an electrical power system when N-1 contingencies occur in the transmission stage, which can be produced by incorrect operation of the protection relays, phenomena of natural origin, or increased loadability, which affect the operation and reliability of the electrical system. The operation output of a transmission line results in the variation of the nominal values of the electrical parameters involved because they disturb the stability of the generation, transmission systems, and the supply of electrical energy to the loads, such as voltages and angles of the nodes and the active and reactive power of the system. The proposed methodology was based on analyzing the different electrical parameters of the power system, quantifying the contingency index in a state of regular operation, and comparing it to operation in contingency N-1, with which the most severe contingency was determined and, therefore, achieved; identifying contingencies that can cause system collapses; improving the contingency index from 23.08555 to 22.9276624 for the L16–19 contingency and to 22.9795235 for the L21–22 contingency, which are the most severe contingencies determined with the proposed methodology. To test the proposed methodology, the IEEE 39 bus-bar test system was considered, and the elements that should be implemented to avoid the vulnerability of the power system to N-1 contingencies were determined.
