Optimal Placement of Unified Power Flow Controller into the Government Feeder Lafia of Abuja Electricity Distribution Network – A Review (Published)
Flexible AC transmission system (FACTS) devices offer great opportunities to regulate the transmission of alternating current (AC) and bus voltages, increasing or decreasing the power flow in specific lines and responding almost instantaneously to the stability problems. The potential of this technology is based on the possibility of controlling the route of the power flow and the ability of connecting networks that are not adequately interconnected, giving the possibility of trading energy between agents. There are many types of FACTS devices depending on the way they are connected in the network such as; series, shunt and the combination of the two. Examples of FACTS devices include; static compensator (STATCOM), Thyristor control series compensator (TCSC), series capacitor synchronous compensator (SCSC), Unified power flow controller (UPFC), Generalized unified power flow controller (GUPFC) etc. Due to the higher reactive power in the Abuja electricity distribution network in particular at government feeder Lafia, there is need to insert UPFC into the feeder in order to minimize this effect. Artificial bee colony (ABC) would be employed for the optimal location of UPFC in the network for power loss minimization and voltage profile improvement. The power flow of the modeled network will be run with and without UPFC optimally located in MATLAB environment to analyze the simulations results and make necessary recommendations.
