“…There is, therefore, an interrelation between the standard of living and the available power delivered in a country [1], [2]. Electricity distribution systems deal with collecting activities and equipment to ensure that power is effectively delivered from the transmission station to the final electricity end-users [3], [4].…”

“…Extensive research works were carried out recently, leading to the discovery of Flexible AC transmission system (FACTS) devices that have been chiefly employed to solve different power system steady-state control problems such as power flow control, voltage regulation, and transferability improvement near-instantaneous response [13]. Many studies [3], [19] have shown that most of the electrical power quality issues directly result from deviations in the network's reactive power. FACTS technology that shows the rapid response to network changes was used by Beagon et al [14] to enhance power network efficiency without changing the network structure.…”

Rising demand for electrical power due to the global technological advancement has brought so many challenges such as instability of voltage, huge power loss, and unstable power factor on the distribution network. This work applied Static Var Compensator (SVC) to the power distribution network of Ado-Ekiti, Nigeria, to study its effect on active power loss reduction and voltage profile improvement of the network. The bus voltage, power, and the current flowing through the selected feeders were measured and recorded accordingly for analysis. Test network parameters like route length, transformer parameters, and maximum power flow were obtained from Benin Electricity Distribution Company, Ado-Ekiti, Nigeria. The distribution network was then modeled and simulated with and without SVC in NEPLAN software environment. The simulation results of the power flow and voltage stability analyses of the network without SVCs showed that some distribution lines were overloaded and that the network parameters were not within the statutory tolerable limits of 0.95 p.u. and 1.05 p.u. nominal voltage. There was 9.73% reduction in the active power loss when SVCs were incorporated into the test network. The voltage stability curve showed an increase in distribution network capacity from an initial steady-state of 150% to 263% of the total active load when the SVCs were incorporated. Hence, the need to normalize the network by applying SVCs to all the buses with very low voltages. This work will assist the power distribution supply companies in making some informed decisions in reducing power losses on their networks.
