Unified Power Flow Controller: Modeling And Dynamic Characteristic
Abstract: Unified power flow controller (UPFC) consists two converters. There are three purposes of this paper, firstly to illustrate the UPFC device based VSC designs, then to describe a decoupling method the UPFC’s controller into two separate control systems of the shunt and the series converters respectively in realizing an appropriate co-ordination between them. Finally, using the Matlab t...
متن کاملImprove dynamic performance of fixed speed wind turbines using unified power flow controller (UPFC) and fractional order controller (FOC)
Wind powers are very unstable in voltage fluctuations, especially in short circuit error and sharp and sudden voltage drops, which one of its main reasons is the use of induction generators in these power plants and thus need to reactive power and high magnetizing current. To improve the ride_through voltage from WECS in error conditions and damping the oscillations of the induction generator r...
متن کاملSwitching Level Modeling and Operation of Unified Power Flow Controller
This proposed work aims at forming a switching level modeling of Unified Power Flow Controller (UPFC) and analyzing its operation. The switching level modeling of UPFC is carried out using high power electronic devices such as IGBT based six pulse shunt and series converters. The operating performance of UPFC is demonstrated on Single Machine Infinite Bus (SMIB) system for different case studie...
متن کاملFuzzy based controller for dynamic Unified Power Flow Controller to enhance power transfer capability
In this paper, a dynamic model of Unified Power Flow Controller (UPFC) is developed to improve the power transfer capability (PTC) through the transmission line. Improvement of the bus voltages profiles along with the reduction of total power losses is also intended with UPFC’s presence. The UPFC shunt and series controllers are developed based on Fuzzy Logic (FL) which has been designed as a s...
متن کاملA CHS based PID Controller for Unified Power Flow Controller
This paper presents a method for designing of proportional-integral-derivative (PID) controller based on unified power flow controller (UPFC) using chaotic harmony search algorithm (CHS) for damping of low frequency oscillations (LFO) in a power system. The main aim of this paper, optimization of selected gains with the time domainbased objective function which is solved by chaotic harmony sear...
