Power quality improvement by using UPFC

2017 2nd International Conference for Convergence in Technology (I2CT), 2017
Power system harmonics is one of the major problems in power system operation. If the harmonics can increases and decreases transmission line capacity which may cause interruption in energy supply. Therefore, flexible AC transmission system (FACTs) devices are employed to reduce this harmonics.

Synchronization of UPFC in Active Distribution Systems

2020
The requirement of power is rapidly increasing so that to meet the increasing demand system needs some effective solutions such as fitting of the solar-based Distributed Generator (DG) and FACTS. Penetration of solar-based DG alters network characteristics, that is, system is active now.

V2G technology to design a virtual UPFC

2012 11th International Conference on Environment and Electrical Engineering, 2012
Unified Power Flow Controller (UPFC) is a FACTS device which can fulfil multiple power flow control objectives such as needs of reactive shunt compensation, phase shifting and series compensation. However UPFCs are quite expensive and therefore are not widely used.

Wide-Area Signal-Based OptimalNeurocontroller for a UPFC

IEEE Transactions on Power Delivery, 2008
The design and implementation of an optimal neurocontroller for a flexible AC transmission device - the unified power flow controller (UPFC) is presented in this paper. Wide area signals in a power system are used to provide auxiliary control to a UPFC in order to achieve enhanced damping of system oscillations.

Modeling of UPFC and its parameters selection

4th IEEE International Conference on Power Electronics and Drive Systems. IEEE PEDS 2001 - Indonesia. Proceedings (Cat. No.01TH8594), 2005
Power systems of today are large and complex, and their control is very difficult. flexible AC transmission systems (FACTS) controllers have been readily accepted as feasible means for power flow control for enhancing the steady and dynamic performances of power system during normal and abnormal conditions.
