Implementation of Unified Power Flow Controller (UPFC) for Power Quality Improvement in IEEE 14-Bus System

In this paper the performance of Unified Power Flow Controller (UPFC) is investigated in controlling the flow of power over the transmission line. This research deals with digital simulation of standard IEEE 14-bus power system using UPFC to improve the real and reactive power flow control through a transmission line by placing UPFC at the sending end using computer simulation. When no UPFC is ...

Optimum Power Oscillation Damping Improvement Using an Add-on Self Tuning Control System for Upfc Application

This project presents a new addon self tuning control scheme to supplement its conventional PI control system in damping low frequency inter area power oscillations. Low frequency (0.1 to 0.8 Hz) inter-area oscillations are often observed when power systems interconnected through weak tie lines are subjected to disturbances such as faults, line outages and sudden load changes. Power System stab...

Minimization of Losses in Distribution Systems for the Improvement of Power Quality by Using UPFC

Minimization of line losses and the improvement of power quality in distribution system are the most challenging problems, particularly when it is not economic to upgrade the entire feeder systems. This paper presents a new method to achieve the line loss minimum condition and improve power quality in radial and loop distribution system by using Unified Power Flow Controllers (UPFC), one of the...

Power Quality Improvement for Grid Connected Wind Energy System Using Upfc

In this paper, a cascaded current–voltage control strategy is proposed for inverters to simultaneously improve the power quality of the inverter local load voltage and the current exchanged with the grid. It also enables seamless transfer of the operation mode from standalone to grid-connected or vice versa. The control scheme includes an inner voltage loop and an outer current loop, with both ...
