The UPFC is a state-of-the-art control device that has the ability to enhance electrical power system network operation more precisely and effectively. This device encompasses of shunt and series parts to readjust capacitive and inductive compensation of the network based on their ratings to dynamically control the operating parameters of the transmission-network. These dynamic parameters comprise of phase angles, line impedance and line voltage. During the detailed investigation, a set of equations are introduced to compute UPFC operations/control behaviour on shared two bus system networks. In fact, the EMTP and Matlab models are introduced and
customized to determine and validate UPFC effectiveness with precision. In this investigation, a pragmatic approach demonstrated and provided roadmap for the planning and control electrical engineer to evaluate UPFC operational behaviour and its significant impact on Electrical power transmission network operations. This device has the ability to address all types of time based contingencies in order for a seamless operation.
