Abstract A shunt–series type of flexible AC transmission system named as Unified Power Flow Controller (UPFC) has an ability to manage real as well as reactive power in the power system network in a simultaneous manner. In this paper, a simulation model of UPFC is tested for the IEEE 14 bus standard test system on the DIgSILENT power factory software. Moreover, an optimum reactive power dispatch problem in presence of UPFC has been solved to reduce the real power loss in transmission lines. The proposed UPFC-based ORPD problem has been solved using the interior point method. The proposed approach is simulated under different loading conditions of the network. A comparative analysis of the obtained simulation results for each loading condition shows the effectiveness of UPFC for real power losses reduction.

1 Introduction Some of the challenges in a modern power system are being overcome by flexible AC transmission system (FACTS) [1]. These challenges are becoming more complex with increasing power demand. Proper management of reactive power in the network is one of them. Due to improper management of reactive power in the network, voltage instability, and real power losses are increasing day by day. Similar to traditional reactive power sources [2], FACTS devices are also capable of compensating reactive power in networks. In this paper, a series–shunt type of FACTS device, namely Unified Power Flow Controller (UPFC) [3, 4], has been used to reduce the total active B. Gaur · R. Ucheniya (B) · A.

power loss in transmission lines. Optimal reactive power dispatch (ORPD) is a traditional and well-known optimization framework, by which the active transmission power loss is minimized, and hence the profile of all bus voltages is also improved [2, 5]. The structure of UPFC is an extraordinary combination of shunt and series elements. Due to which, it can regulate various transmission parameters such as line impedance, node bus voltage as well as angle. It can be able control both real as well as reactive power flow in the transmission line and improve the performance of the grid [1, 6]. In this paper, the performance of an UPFC connected in IEEE 14 bus test system [7] is investigated on the DIgSILENT power factory software simulation platform [8].
