“…The two foremost types of LVRT capability enhancement methods are external devices based methods and modified controller based methods. Energy Storage Systems (ESSs) , Braking Chopper (BC) or active crowbar system [66][67][68][69][70], FACTS devices [71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87][88][89][90] and some other methods such as Series Dynamic Breaking Resistor (SDBR), electronic on Load Tap Changer (OLTC) [91][92][93][94][95] are popular methods for LVRT capability enhancement using external devices. Pitch Angle Control (PAC) [96][97][98][99] and modified back-to-back converter controllers [100][101][102][103][104][105][106][107][108] are modified controller based methods.…”

Determining maximum loading margins is an important issue in power system operation, as system operators must take proper preventive actions to avoid stability problem. This paper presents a study of parallel FACTS devices and series FACTS devices on steady-state voltage and power stability. Their steady state modeling and effects on power system performance have been studied. It also studies static stability improvement of the power system and hence power flow improvement in the network. Effects of FACTS on system loadability have been discussed and presented here. A method based on the concept of maximum loading point index has been used to compare FACTS devices. The study has been carried out on the IEEE 14 bus test system. The line power transfer capability and loadability of the system and therefore, the stability of the system is increased. It has also been observed that for the improvement of these parameters, the parallel FACTS devices are more adequate than the series FACTS devices.

“…It is concluded that for the power system networks which operates very close to the steady-state stability limit and may result in voltage instability and/or voltage collapse, use of flexible alternative current transmission system (FACTS) devices can prove a good choice for improving the static voltage stability margin [3]. FACTS family include thyristor controlled series compensator (TCSC), static Var compensator (SVC), unified power flow controller (UPFC), static synchronous compensator (STATCOM) etc [4][5][6][7][8]. Application of FACTS results in power flow control smoothly and rapidity [9].…”

Improving voltage stability, reducing real power loss (PL) and voltage deviation (VD) are the most important tasks in the operation of electrical power systems. Voltage instability and voltage collapse are the severe problems which may take place because of deficit reactive power at load buses due to increased loading or contingencies. In this paper, the problem of obtaining optimal location and size of SVC is formulated as true multi-objective optimization problem for simultaneous minimization of the two objectives namely real power losses and load bus voltage deviation. The two algorithms real coded genetic algorithm (RCGA) and non-dominated sorting genetic algorithm-II (NSGA-II) with a feature of adoptive crowding distance have been used for solving nonlinear constrained multi-objective optimization problem. Both the algorithms have been used for obtaining optimal location and sizing of SVC. Voltage security of the power system has also been analyzed separately for all placement of SVC to ensure secure operation of the system. The proposed approaches have been implemented on IEEE 30-bus test system. The simulation results of the two algorithms have been compared for solution quality, computational complexity and computational time. It has been found that NSGA-II presents better performance in solving multi-objective optimization problem and also in obtaining a diverse set of solutions which converge near the true Pareto-optimal front. The simulation results of NSGA-II have also been presented to exhibit the capabilities of the algorithm to generate well-distributed Pareto-optimal front.
