“…The inequality constraints (8) and (9) correspond to keeping the voltage magnitude at each bus and the variable reactance of each TCSC within their limits. As defined in (5) and explained earlier, the capacity margin of a line is the difference between the active power flowing through this line and its capacity divided by its capacity. If the active power flow through a line does not exceed its capacity, the capacity margin is positive; otherwise it is negative.…”

“…To achieve the optimal usage of the transmission system with FACTS devices, the optimal settings of these devices need to be determined. Traditionally, this can be done by solving an optimal power flow (OPF) problem either in a centralised [2][3][4][5][6] or a decentralised way [7]. The centralised approach directly solves the OPF problem for the whole system by providing the optimal device settings that benefit the system the most, however, it needs the information from the entire system.…”

In emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS devices can regulate the active and reactive power control as well as adaptive to voltage-magnitude control simultaneously because of their flexibility and fast control characteristics. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve voltage stability margins.This paper proposes a systematic method by which optimal location of MUTI TYPE FACTS DEVICES to be installed. FACTS DEVICES model is incorporated into a NewtonRaphson algorithm to perform load flow analysis. Optimizing its location becomes a concern when coming to the practical implementation stage. Proposed algorithm is tested on IEEE 5 bus power system for optimal allocation of multi-type FACTS devices and results are presented.

“…Controlling the power flows in the network, under normal and abnormal conditions of the network, can help to reduce flows in heavily loaded lines, reduce system power loss, and so improve the stability and performance of the system without generation rescheduling or topological changes in the network [1]. Because of the considerable costs of the FACTS devices, it is so mementos to find out the optimal location for placement of these devices to improve voltage stability margins and enhance network security [2][3][4][5][6][7].…”

Modern power systems are prone to widespread failures. With the increase in power demand, operation and planning of large interconnected power system are becoming more and more complex, so power system will become less secure. Operating environment, conventional planning and operating methods can leave power system exposed to instabilities. Voltage instability is one of the phenomena which have result in a major blackout. Moreover, with the fast development of restructuring, the problem of voltage stability has become a major concern in deregulated power systems. To maintain security of such systems, it is desirable to plan suitable measures to improve power system security and increase voltage stability margins. FACTS devices can regulate the active and reactive power control as well as adaptive to voltagemagnitude control simultaneously because of their flexibility and fast control characteristics. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve voltage stability margins. This paper presents a Genetic Algorithm (GA) based allocation algorithm for FACTS devices considering Cost function of FACTS devices and power system losses. Proposed algorithm is tested on IEEE 30 bus power system for optimal allocation of multi-type FACTS devices and results are presented.
