The distributed power flow controller (DPFC) represents an advancement over the unified power flow controller (UPFC). In contrast to the UPFC, the DPFC removes the DC link connecting the shunt and series converters, and redistributes the series converters along the transmission line as single-phase static series compensators. This modification enhances grid performance while maintaining full power flow control capabilities. The DPFC offers several advantages over the UPFC, including higher reliability, improved controllability, and greater cost-effectiveness. The system comprises a shunt converter in conjunction with multiple series converters, each with its own control circuit, all managed by a central control unit. This article presents the implementation of a DPFC model in MATLAB/Simulink. The simulation outcomes indicate that the DPFC significantly contributes to improved voltage stability and enhanced power transfer capability, thereby reinforcing system performance and reliability.

INTRODUCTION Electricity has become increasingly integral to modern life since the establishment of the Edison Electric Light Company, which initiated the development of steam-powered power stations on Pearl Street in New York City under the leadership of inventor Thomas Edison [1], [2]. Over the past century, there has been a remarkable surge in both the consumption and generation of electricity [3], [4]. For instance, global electricity consumption has reached a staggering tens of Tera kWh, and this figure continues to grow [5]-[7]. An electrical power system comprises the processes of generation, transmission, distribution, and end-use of electrical energy, serving as the fundamental infrastructure for energy delivery to consumers. Electricity is typically produced in centralized generating stations and transported through interconnected transmission and distribution networks to reach end-users. Throughout the transmission phase, power flow— referring to the movement of both active and reactive power across transmission lines —plays a critical role in maintaining system efficiency and stability [8]-[10]. Over the past thirty years, the landscape of electrical power generation has undergone a profound transformation, marked by a remarkable surge in capacity. This surge has necessitated a fundamental restructuring of the power system's operational framework, demanding innovative solutions to accommodate the evolving demands of an increasingly electrified world. In tandem with this shift, the relentless march of
