Abstract
Electrical power demand is increasing at a relatively fast rate over the last years. Because of this increasing demand the power system is becoming very complex. Both electric utilities and end users of electric power are becoming increasingly concerned about power quality. This paper presents a new concept of distributed power flow controller (DPFC), which has been implemented with a proton exchange membrane (PEM) fuel cell. In this paper, a PEM fuel cell has been simulated in Simulink/MATLAB and then has been used in the proposed DPFC model. The new proposed DPFC model has been tested on a IEEE 30 bus system.
Highlights
Power quality improvement is a major concern of the power industry [1]
The DC source that is used in distributed power flow controller (DPFC) has been replaced by a proton exchange membrane (PEM) fuel cell
It mainly consists of five units namely, fundamental frequency model, 3rd harmonic model, series converter model, shunt converter model and control unit
Summary
Power quality improvement is a major concern of the power industry [1]. Custom power devices are used [2]. FACTS devices, such as unified power flow controller (UPFC) and synchronous static compensator (STATCOM), are used to alleviate the disturbance and improve the power system quality and reliability [3, 4]. The distributed power flow controller (DPFC) is a device in the FACTS family, derived from the UPFC. Compared with the UPFC, DPFC has the same controlling capability to change all the parameters within the transmission system. Fuel cells are electrochemical devices that convert chemical energy of a fuel directly to electric energy, without any moving parts [5, 6]. The performance of the proposed new model of DPFC is compared with some existing conventional DPFC models to check its performance
