Exposure to extreme weather conditions increases power systems’ vulnerability in front of high impact, low probability contingency occurrence. In the post-restructuring years, due to the increasing demand for energy, competition between electricity market players and increasing penetration of renewable resources, the provision of effective resiliency-based approaches has received more attention. In this paper, as the major contribution to current literature, a novel approach is proposed for resiliency improvement in a way that enables power system planners to manage several resilience metrics efficiently in a bi-objective optimization planning model simultaneously. For demonstration purposes, the proposed method is applied for optimal placement of the thyristor controlled series compensator (TCSC). Improvement of all considered resilience metrics regardless of their amount in a multi-criteria decision-making framework is novel in comparison to the other previous TCSC placement approaches. Without loss of generality, the developed resiliency improvement approach is applicable in any power system planning and operation problem. The simulation results on IEEE 30-bus and 118-bus test systems confirm the practicality and effectiveness of the developed approach. Simulation results show that by considering resilience metrics, the performance index, importance of curtailed consumers, congestion management cost, number of curtailed consumers, and amount of load loss are improved by 0.63%, 43.52%, 65.19%, 85.93%, and 85.94%, respectively.

“…L-index used in [10][11][12][13], to determine the bus bars from where the collapse may originate, for FACTS devices allocations. Other indices like line security margin index [14], voltage security index [15], security index [16], controllability index [17] were also used to find the location of UPFC to fix voltage instability problems.…”

This paper presents a placement method of fuzzy logic based unified power flow controller (UPFC) in power system network by analyzing dynamic voltage stability. Voltage stability indices namely LQP and voltage collapse point indicators (VCPI) indices are used to determine the weakest line for UPFC by dynamic load variation. The controllers of the shunt and series converters of the UPFC are developed using fuzzy logic (FL) and proportional integral (PI) controllers respectively to enhance the dynamic voltage stability of the power system network.The simulation has been conducted in power system computer-aided design (PSCAD) environment where IEEE-5 and IEEE-14 bus system have been chosen as test bench systems. The results obtained through simulations have ensured the effectiveness of the proposed placement method since fuzzy based UPFC's placement in the obtained locations resulted in significant improvment in voltage stability.

“…For the operation of power system, control of active and reactive power flow is very significant [2]. The variables and parameter of the transmission line, which comprise line reactance, voltage magnitude, and phase angle are capable to be controlled by means of FACTS controllers in a rapid and successful way [3][4][5]. The advantages obtained from FACTS consist of improvement of the stability of power system networks, such as voltage stability, line stability, small signal stability, transient stability, and hence improve system dependability [6] [7].…”

FACTS devices plays a significant role to control the power flow of power transmission system. In this paper, a hybrid PSO algorithm is proposed to optimize the location of UPFC in power system. The proposed hybrid PSO algorithm has solved the formulated multiobjective optimization problem. This paper, five objective function to be considered in the form of minimization such as the fast voltage stability index (FVSI), fuel cost, power loss, voltage deviation and UPFC cost respectively. To improve the non satisfied solution of PSO algorithm, bat search optimization is used and the performance of PSO algorithm is enhanced. The proposed hybrid technique is implemented in MATLAB working platform which is tested with IEEE 14 bus bench mark system. Here, two load cases are considered to evaluate the proposed method and compared with traditional PSO algorithm. The comparative analysis are conformed the effectiveness hybrid PSO algorithm for solving multiobjective optimal power flow problem.
