Contingency analysis has been considered as critical issue in power systems because it initiates failures transmission line and failure equipment. Hence, this paper is presented Red Deer Algorithm (RDA) to manage contingency condition for improving security of the system. The proposed algorithm utilized solve Optimal Power flow (OPF) with multi-objective functions. function consisting six singl...

A unified power flow controller (UPFC) based on the flying capacitor (FC) multilevel voltage-source converter (VSC) topology with phase-shifted sinusoidal pulse-width modulation (PWM) control is presented. This converter allows higher power handling, potentially lower power loss, lower harmonic distortion and hence less filtering requirements when compared with the typical two-level counterppar...

This paper proposes a new control approach for a unified power flow controller (UPFC) for power system oscillation damping. This control is simple to implement, yet is valid over a wide range of operating conditions. It is also effective in the presence of multiple modes of oscillation. The proposed control is implemented in several test systems and is compared against a traditional PI control.

In this paper we proposed an advanced Multi-level converters with ride through capability for unified power-flow controller (UPFC) applications, because of high power ratings Among all multilevel topologies, the three-level neutral-pointclamped (NPC) converter allows back-to-back connection as the UPFC shunt and series converters gives us better results. Besides the pulse widthmodulated (PWM) m...

The Unified Power Flow Controller (UPFC) can provide simultaneous control of all basic power system paramaters (transmission voltage, impedance and phase angle). The controller can fulfill functions of reactive shunt Compensation, series compensation and phase shifting, meeting multiple control objectives. From a functional perspective, the objectives are met by appliying a cross coupling contr...
