Feasibility of incorporating FACTS devices and DG to optimize the performance of Pakistan's transmission network: A case study

Abstract

Limited resources and environmental regulations have led to significant increases in power usage during the last few years in Pakistan. Thus, a lack of system stability is a limiting issue in power transfer due to some transmission lines being excessively overloaded in the network. The main goal is to enhance the infrastructural improvements in transmission that have been made possible by integrating Flexible AC transmission systems (FACTS) and distribution generators (DGs). These improvements have helped reduce the complexities caused by power losses and voltage stability issues in the transmission network. By incorporating DGs and UPFC devices into transmission networks, this research delivers voltage increase as well as power fatalities in transmission networks. With the use of actual data for analysis and simulations using the NEPLAN simulator, we developed Midway Node UPFC modeling for a 132kV transmission network that transfers power to the Quetta Electric Supply Company (QESCO) network. Simulating UPFC and DGs in the transmission network helps examine the changes in voltage profiles and power losses in four different scenarios. Furthermore, it lowers the overall transmission losses while simultaneously enhancing the overall transmission efficiency.
