Abstract:
Reactive power (RP) plays a substantial role in transmission network efficiency.
Though, the management of reactive power is extremely challenging for utility companies
with diverging loads and deviating seasonal conditions. To cope with the reactive power
flow ofthe transmission network, that is a dense network of lines (transmission) deals with
different voltage levels, substations or grid stations and, different types oftransformers.. In
this research, the Transmission network of a utility company (radial system) selected to
analyze the reactive power management (RPM) and optimizing their transmission losses for
this Transmission losses were simply calculated by using the load flow method of a power
system, while technical losses were calculated by suitable load-flow studies simulated
under the Power System Simulator for Engineering (PSSE) Software. The model presented
in this study was simple, work on different phases, and easily applicable to a large
transmission network comprising several buses, After the simulation studies, it was
observed that the control and management of reactive power by adding the different sizes
of capacitors locate on different buses at the transmission network of a utility company is
adequate to improve the voltage profile in the selected case study. It not only improves the
transformer’s loading but also provides system stability to the case study along with the
reduction ofstress levels on the entire network of a utility company.
