“…SVC is a reactive power compensator connected in parallel to the circuit to control and stabilize certain parameters (especially bus voltage) of the power system (Das, Sen, Gupta, Shegaonkar, & Acharjee, 2018). SVC is used to control the bus voltages and protect the power system by adjusting the capacitive or inductive current with the output signal.…”

There are many situations that cause voltage instability in power systems. One of these situations is line contingency that may occur in power systems. In this study, the effects of line contingency on the steady state are investigated in the IEEE 9 buses power system. Firstly, the static and dynamic analyses of the power system are made in normal operating condition. Continuous power flow analysis was used as static analysis and time domain simulation method were used as dynamic analysis. Then each transmission line is deactivated and the analyses are repeated. The changes in the maximum loading capacity and voltage stability of the system are investigated in case of each transmission line contingency. Finally, Static Var Compensator (SVC) is connected to the power system to improve the stability level. When the SVC is connected to the power system, the maximum loading capacity of the system is examined and the effects of this situation on the voltage stability are analyzed. All analyses are performed in the MATLAB® PSAT (Power System Analysis Toolbox). The results showed that the line contingency reduces the maximum loading capacity and deteriorates the voltage stability. It has been observed that both the problems can be eliminated with the SVC integration into the power system.

“…The models of TCSC and SVC necessary to understand the effect on the system to improve dynamic voltage stability have been reported [20] . Further, the voltage stability constrained optimal power flow formulation by combining TCSC, SVC, and UPFC has been presented [21] . This formulation affects the topology, and hence, the power flow.…”

In recent years, voltage stability issues have become a serious concern with regard to the safety of electrical systems, these issues are more evident and have wider consequences in vertical networks with an insufficient reactive power reserve. Pakistan is currently suffering from the worst energy crisis in its history. Owing to an increase in energy demand, the current transmission system is becoming increasingly inadequate. It has thus become necessary to reduce losses and enhance the system voltage profile for more efficient energy utilization. In this study, the main emphasis is on assessing the feasibility of using flexible AC transmission system devices and distributed generation to compensate power failures on the power lines of the Pakistani power transmission system. The load flow and contingency analyses are performed on a 132 kV transmission system that feeds power to the Quetta electric supply company. The region of Baluchistan is studied to evaluate the effectiveness of the proposed method. The system is simulated using NEPLAN, which accurately models the details of all system elements and the optimal power flow. The simulation results indicate that the proposed method helps reduce system losses, voltage deviation, and power flow congestion, with all system constraints within permissible limits.
