Center-node Unified Power Flow Controller (C-UPFC) is a recent developed Flexible AC Transmission System (FACTS) device. C-UPFC is a combined shunt-series controller that connected at the midpoint of transmission lines to control various parameters such as, voltage magnitude at midpoint of line, active and reactive powers flow at both ends of line. This paper proposed an efficient modelling with handling ... إقراء المزيد

This study proposes the generalised unified power flow controller (GUPFC) model in the hybrid current power mismatch Newton–Raphson formulation (HPCIM). In this model, active power, real and imaginary current components are injected at the terminals of series impedances of GUPFC. These injected values are calculated during the iterative process based on the desired controlled values and buses voltage at the ... إقراء المزيد

Static Synchronous Series Compensator (SSSC) is an efficient member of Flexible AC Transmission Systems (FACTS) devices. SSSC is connected in series with transmission lines to control the active and reactive power flow in these lines. In this paper, Grey Wolf Optimization (GWO) algorithm is developed for solving the optimal reactive power dispatch (ORPD) problem. The ORPD problem is solved with ... إقراء المزيد
