reactive power management and OPTIMIZATION OF TRANSMISSION LOSSES FOR TRANSMISSION NETWORK

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.
