“…The magnitude and phase angle of the injected voltage in the prime system can be controlled by exchanging real power with the support system. The master converter controls both active and reactive voltage (within limits) while the slave converter controls the DC voltage (across the capacitor) and the reactive voltage magnitude ( Jaya Christa and Venkatesh, 2013).…”

“…Minimization of the total cost of operating a power system by allocating multiple FACTS devices like TCSC and static var compensator (SVC) has been discussed (Wibowo et al , 2011). Interline power flow controller (IPFC) is a series-series compensation FACTS device which can be modelled to reuse Newton Raphson power flow codes (Zhang et al , 2006; Jaya Christa and Venkatesh, 2013). Researchers have proposed optimal allocation methods for IPFC to relieve congestion using sensitivity indices.…”

Purpose The purpose of this paper is to optimally locate and size the FACTS device, namely, interline power flow controller in order to minimize the total cost and relieve congestion in a power system. This security analysis helps independent system operator (ISO) to have a better planning and market clearing criteria during any operating state of the system. Design/methodology/approach A multi-objective optimization problem has been developed including real power performance index (RPPI) and expected security cost (ESC). A security constrained optimal power flow has been developed as expected security cost optimal power flow problem which gives the probabilities of operating the system in all possible pre-contingency and post-contingency states subjected to various equality and inequality constraints. Maximizing social welfare is the objective function considered for normal state, while minimizing compensations for generations rescheduling and maximizing social welfare are the objectives in case of contingency states. The proposed work is viewed as a two level problem wherein the upper-level problem is to optimally locate IPFC using RPPI and the lower-level problem is to minimize the ESC subjected to various system constraints. Both upper-level and lower-level problem are solved using particle swarm optimization and The performance of the proposed algorithm is tested under severe line outages and has been validated using IEEE 30 bus system. Findings The proposed methodology shows that IPFC controls the power flows in the network without generation rescheduling or topological changes and thus improves the performance of the system. It is found that the benefit achieved in the ESC due to the installation of IPFC is greater than the annual investment cost of the device. ISO cannot achieve minimum total system cost by merely rescheduling generators. Instead of rescheduling, FACTS devices can be used for compensation by achieving minimum cost. IPFC can be used to compensate the congested lines and transfer cheaper power from generators to consumers. Originality/value Operational reliability, financial profitability and efficient utilization of the existing transmission system infrastructure has been achieved using single FACTS device. Instead of using multiple FATCS devices, if a single FACTS device like IPFC which itself can compensate several transmission lines is used, then in addition to the facility for independently controlled reactive (series) compensation of each individual line, it provides a capability to directly transfer real power between the compensated lines. Hence an attempt has been made in this paper to incorporate IPFC for relieving congestion in a deregulated environment. However, no previous researches have considered incorporating compensation of multi-transmission line using single IPFC in minimizing ESC. Thus, in this paper, the authors indicate how much the ESC is reduced by installing IPFC.

This article aims to propose a novel single-end protection scheme for the compensated transmission line using traveling waves and game theory. First, this study evaluates the effects of thyristor controlled series capacitor (TCSC) on traveling waves (TW) passing through TCSC location. Following that, it investigates the impacts of TCSC switching on conventional protections based on the traveling wave theory. In the next stage, a single-end method will be presented to protect faults on compensated transmission lines with TCSC. Moreover, the game theory will be employed to discriminate extracted TWs in this article. In total, two techniques (ie, mathematical morphology filter [MMF] and discrete wavelet transform [DWT]) will be used to process the signals and investigate the sensitivity of the proposed scheme regarding the extraction techniques of TW. The proposed protection scheme is revealed to be a reliable and accurate method for all possible types of faults on compensated transmission lines at the middle of the line and with various fault inception angles.

Modern electric power utilities are facing many challenges due to increasing complexity in their operation and structure. In the recent times, one of the problems that got wide attention is the power system instabilities due to lack of new transmission facilities. Existing transmission facilities can be better utilized by installing Flexible AC Transmission System (FACTS) devices. The TCSC is the most effective FACTS device used to increase the power transferable capabilities of the transmission line. This paper presents a Sensitivity analysis based Complex Power Flow Sensitivity Index (CPSI) calculated for placing the TCSC at an appropriate location. Once the location to install the TCSC is determined, the optimal tuning of the TCSC is determined through BAT Algorithm. The BAT Algorithm is implemented on multi-criterion objective function to minimize total real power loss, total voltage magnitude deviations, the fuel cost of total real power generation and the branch loading to obtain the Optimal Power Flow. Simulations have been carried out in MATLAB software for the IEEE 57-bus system. The results have been taken for BAT Algorithm based Optimal Power Flow without and with TCSC. The results obtained with BAT Algorithm were compared with Genetic Algorithm (GA).
