“…Also, the optimal placement of these FACTS devices was not discussed. An attempt to identify causes of system collapse on an island mode in the Nigeria grid was carried out in [17] and contingencies analysis in [18]. Low voltage profile was experienced at Benin bus [17] upon simulation of faults in steady and dynamic states while capacitors were placed in the network in [18] for systems efficiency.…”

In this paper, the optimal placement of Unified Power Flow Controllers (UPFC) in a large-scale transmission network in order to improve the loadability margin was considered. In other to achieve this aim, the Line Stability Factor (LQP) as a technique for the optimal location of UPFC in the IEEE 14-bus network and 56-bus Nigerian national grid was adopted. The power injection model for the UPFC was employed to secure improvements in the loading margin of the IEEE 14-bus network and 56-bus Nigerian national grid system. Continuation power flow was used to assess the effect of UPFC on the loadability margin. Steady-state simulations using Power System Analysis Toolbox (PSAT) on MATLAB was applied to determine the effectiveness of placing UPFC between bus 13 and bus 14 in the IEEE 14-bus network and between bus 44 (Ikot-Ekpene) and bus 56 (Odukpani) in the 56-bus Nigerian national grid system. The results showed that the loadability margin increased by 8.52 % after UPFC was optimally placed in the IEEE 14-bus network and increased by 195.5 % after UPFC was optimally placed in the 56-bus Nigerian national grid system. Thus, these enhance the voltage stability of both network and utilizing the network efficiently.

“…The 1P1Q method comprises of the Power Performance Index and the Performance Voltage Index [5]. The Power Performance File (PIflow) positions with regard to the stream of dynamic control within the electrical framework whereas the Execution Voltage File (PIV) is based on the voltage on the bus within the electrical system [1], [12] - [22].…”

A major factor in the power system operation is the desire to maintain system security. System security involves a design to keep the system operating in the event of interference or failure. Interferences in electrical power systems are divided into generator, transmission, and load. Failure or interference of the transmission network results in a contingency of the transmission lines that can cause voltage in the bus and overload in the transmission lines, so it is very necessary to overcome the problem with a contingency analysis simulation to find solutions to problems caused by the disconnection of the transmission line. One of the contingency analysis methods is the 1P1Q (performance contingency index) method where the 1P1Q method lists the worst contingency impact on the electric power system to help engineers to solve problems and determine their next steps when contingencies occur. In the study, the Newton raphson's methods were used to determine the power flow in electrical systems at normal conditions or contingency. Calculating the value of the contingency index in times of interference or failure using the 1P1Q method. The results show that the worst impact or highest-ranking performance index for the Madura 150 kV electric power system occurs in the infinity-base scenario where two lines are overloaded and exceed the maximum value limit of the transmission line power of the infinity-gilitimur channel of 157.5 MW with a maximum value limit transmission line of 92,359 MW and gilitimur-bangkalan of 149 MW with a maximum value limit of transmission line of 88,616 MW. So there is prevention with load shedding of 87,638 MVA with scenario 6 in table 4:24 of load shedding on the bus Sampang, Sumenep, Pamekasan because by shedding loads of 95,528 MVA the power flowing at infinity-gilitimur becomes 72.9 MW.
