Transmission series power flow control

“…Use of static phase shifters and FACTS controllers for the purpose of increasing power transfer capacity in the transmission line is described in [3] & [4]. In [5] authors have discussed about the power flow control in transmission network. About the modeling and selection of possible locations for the installation of FACTS devices have been discussed in [6].…”

This paper presents Differential Evolution (DE) based approach for the allocation & coordinated operation of multiple FACTS (Flexible AC Transmission System) devices for the improvement of power transfer capacity in an interconnected power system. The DE based approach is applied on IEEE 30-bus system. The system is reactively loaded starting from base to 200 % of base load. FACTS devices are installed in the different locations of the power system and system performance is noticed with and without FACTS devices. First, the locations, where the FACTS devices to be placed is determined by calculating active and reactive power flows in the lines. A Differential Evolution based algorithm is then applied to find the amount of magnitudes of the FACTS devices. A comparative analysis with PSO (Particle Swarm Optimization) is also done. This approach of Differential Evolution based placement of FACTS devices is tremendous beneficial both in terms of performance and economy is clearly observed from the result obtained.

Increasing electric power consumption cause transmission lines to beyond their transfer capacities resulting in overloaded lines and congestions. A flexible AC transmission system (FACTS) in a power system improves the stability, reduces total losses and cost of generation and also improves loadability of the system by controlling power flows and bus voltages.The focus in this paper is using Static Var Compensator (SVC) as a shunt reactive power compensator in order to minimize power losses and compensate voltage sags. Optimal reactive power sizing and avoiding compensating unnecessary buses in IEEE 30-bus electrical power system has been obtained by using fuzzy logic (FL) concept in this paper.Transmission line removing, transmission grid extensions, load changes conditions have been simulated in the paper and obtained results prove the robustness and reliability of fuzzy logic algorithm in different conditions of power system.
