This paper presents a novel technique based on Cuckoo Search Algorithm (CSA) for enhancing the performance of multiline transmission network to reduce congestion in transmission line to huge level. Optimal location selection of IPFC is done using subtracting line utilization factor (SLUF) and CSA-based optimal tuning. The multi objective function consists of real power loss, security margin, bus voltage limit violation and capacity of installed IPFC. The multi objective function is tuned by CSA and the optimal location for minimizing transmission line congestion is obtained. The simulation is performed using MATLAB for IEEE 30-bus test system. The performance of CSA has been considered for various loading conditions. Results shows that the proposed CSA technique performs better by optimal location of IPFC while maintaining power system performance

Power Flow Controller

A power system structure has the generation, transmission and the distribution systems. During the transfer of power from the generation system to the distribution system, transmission line losses are occurred. To reduce the losses and keep the system stable, many controllers are being used. The Flexible AC Transmission systems (FACTS) are the modern controllers finding application in the power systems. The Unified Power Flow Controller (UPFC) is considered to be the best among the FACTS devices. It is installed in the transmission line to maintain the voltage of the system within the prescribe limits. The location to fix the UPFC is found using Shuffled Leap Frog Algorithm (SLFA). The transformer ratio is varied from its nominal value. Testing is done using an IEEE 30 bus system and the results are discussed.

Introduction: Relevancies of electrical power system to consumers cannot be overemphasized. This requires healthy operation of such system. 132/33KV network is an important network within the transmission system and its importance calls for effective and efficient operation. However, due to the long distance at which the transmission line span, the nature of the lay (either overhead or underground) and type of cable used, there are series of voltage instability and power loss along the transmission network which are threat both economically and technically to both electricity providers and consumers because of the cost implication of the losses and effect on the stability of the network. Aims: This research aims is to seek optimal placement of a capacitor bank to proffer solution to both voltage instability and power loss problem by simulating Ondo 132/33KV transmission network using NEPLAN software. Methodology: The network model was developed using NEPLAN software. The voltage profile and power loss with and without capacitor bank were determined from power load flow solutions using Newton-Raphson method. Results: Effects of optimal placements of capacitors along the studied transmission line is established. Conclusion: Proper installation of capacitor bank is also found to enhance performance with an accompanied improvement in voltage profile along the buses.
