Design of a neural network based distributed power flow controller (DPFC) for power system stability

To overcome the drawbacks of the conventional UPFC, this work proposed and Designed a new UPFC technology that addresses these impediments. This novel technology is called the Distributed PFC (DPFC). The proposed DPFC is based on single-phase system, considering the high voltage insulation, the manufacturing cost, and the installation requirement. A hierarchy control of the DPFC system is proposed, which includes local unit control and a central control unit. The central control unit calculates series voltage and shunt real/reactive power commands for every DPFC unit. The local DPFC unit accepts commands from the central control unit, monitors local voltage at the connection point, and realizes its control commands. The functions and performance of the DPFC system is verified with simulation and experiments.
