“…Voltage instability phenomenon can be described as a process where the receiving end voltage decreases well below its normal value and does not come back even after using restoring mechanisms. This may further result in voltage collapse where the voltage falls to an unacceptable value [8].…”

“…In the IEEE 39 bus test system, the lines between PQ-PQ buses are lines 1,3,4,5,6,7,8,9,10,11,12,13,14,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,38,39 And the lines between PQ-PV buses are lines 2,15,35,36,37,41,42,43,44,45,46. TCSC is installed on both PQ-PQ buses and PQ-PV buses to observe its effect on both types of lines.…”

“…The SVC positioning and N−2 contingencies were considered to augment the loadability margin and also Bender's decomposition approach was also exploited in [10]. The SVC compensator for voltage stability enhancement was presented in [11]. To discover the optimal positioning and rating of the TCSC and SVC, a bifurcation analysis was exploited in [12].…”

This paper proposes a hybrid approach on the basis of the Optimal Positioning and Sizing (OPAS) to enhance the dynamic stability for Unified Power Flow Controller (UPFC). Moreover, the maximum power loss bus is recognized during the optimum positioning by putting the UPFC, as the generator outage have effects on the power flow constraints namely voltage, real and reactive power flow, and loss of power. By exploiting the Particle Swarm Optimization (PSO) method, the optimum position is determined. According to violated power flow quantities, the Salp Swarm Algorithm (SSA) optimizes, which is necessary for UPFC quantity in order to get better initial operating circumstance. Subsequently, the proposed and conventional methods are simulated in the MATLAB platform and the performance of the proposed approach is examined by comparing conventional approaches like Genetic Algorithm (GA), PSO, and Artificial Bee Colony (ABC). Finally, the results revealed that the performance of the proposed approach is enhanced and validate it's possible to resolve the crisis.

“…The appropriate representation including the equations in the DC parts of SVC and STATCOM is incorporated in the continuation power flow (CPF) process in static voltage stability study. Many works in the literatures [10], [11], [12], however, considers only the AC equations for voltage stability study. This may lead to non-practical solutions in the DC parts of the FACTS devices.…”

In this paper, voltage stability assessment with appropriate representations of STATCOM, TCSC and SSSC is investigated and compared in the modified IEEE 14-bus test system. AC and DC representations of STATCOM, TCSC and SSSC are used in the continuation power flow process in static voltage stability study. The appropriate representation provides more practical solutions in the dc parts of these devices. Static voltage stability margin enhancement using STATCOM, TCSC and SSSC is compared in the modified IEEE 14-bus test system.
