The detection of potential voltage collapse in power systems is essential to maintain the stability heavy load demand. This paper proposes a method detect weak buses using two indices: margin factor (dS/dY) and prediction index (VCPI). Hence, aims improve Iraqi transmission grid by allocating FACTS devices optimal locations sizes. Two types are used this which Thyristor controlled series compen...

Instead of building new substations or transmission lines, proper installation of flexible AC transmission systems (FACTS) devices can make the transmission networks accommodate more power transfers with less expansion cost. In this paper, the problem to maximize power system loadability by optimally installing two types of FACTS devices, namely static var compensator (SVC) and thyristor contro...

Existence of many different Operators in the new electricity has brought many challenges in the system operation and control to obtain minimum generation cost and security. With the growing demand of electricity in the competitive electricity market environment, one or more transmission lines could be overloaded, therefore causing congestion. The congestion can be eliminated/alleviated by impro...

technique is applied to design a Thyristor Controlled Series Compensator (TCSC)-based controller to enhance the power system stability. Two types of controller structures, namely a lead-lag (LL) and a proportional-integral-derivative (PID) are considered. Further, for the optimization of proposed controller parameters, two objective functions namely Integral Square Error (ISE) and Integral of T...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission an...

This paper investigates the performance of the single TCSC and proposed split TCSC on transmission system where India’s first TCSC project is installed in Kanpur Ballabhgarh (KB) line to ensure the fine tuning of line reactance by proposed split TCSC in place of existing KB TCSC. A three phase KB transmission system is developed in MATLAB/Simulink (SimPowerSystems) for a) without any compensati...

This paper investigates the application of Particle Swarm Optimization (PSO) technique for coordinated design of a Power System Stabilizer (PSS) and a Thyristor Controlled Series Compensator (TCSC)-based controller to enhance the power system stability. The design problem of PSS and TCSC-based controllers is formulated as a time domain based optimization problem. PSO algorithm is employed to se...

This paper presents a new scheme of thyristor controlled series compensators (TCSC)-based damping controller for inter-area oscillations in bulk power systems based on wide area measurement system (WAMS). In this regard, the proposed provides an adaptive three-phase step through real-time working mode. first step, by proposing dynamic clustering-based technique, signals evaluate which procedure...

This paper deals with the simulation of fixed capacitor Thyristor switched Reactor Thyristor controlled reactor (FC-TSR-TCR) system. The FC-TSR-TCR system is simulated using MATLAB and the simulation results are presented. The power and control circuits are simulated. The current drawn by the FCTSR-TCR varies with the variation in the firing angle. Stepped variation of current can be obtained u...
