Damping inter-area oscillations using virtual generator based power system stabilizer

Design Supplementary Controller Based on Stabilizing Effect of Delay for Damping Inter Area Oscillations in a Power System

The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...

Inter-Area Oscillation Damping With Non-Synchronized Wide-Area Power System Stabilizer

One of the major issues in an interconnected power system is the low damping of inter-area oscillations which significantly reduces the power transfer capability. Advances in Wide-Area Measurement System (WAMS) makes it possible to use the information from geographical distant location to improve power system dynamics and performances. A speed deviation based Wide-Area Power System Stabilizer (...

Design of Wide-area Damping Control Systems for Power System Low-frequency Inter-area Oscillations

Coordinated Control of Doubley Fed Induction Generator Virtual Inertia and Power System Oscillation Damping Using Fuzzy Logic

Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...

Nonlinear Control of UPFC in Power System for Damping Inter Area Oscillations

This paper introduces a new nonlinear control of flexible ac transmission systems (FACTS) controllers for the purpose of damping interarea oscillations in power systems. FACTS controllers consist of series, shunt, or a combination of series-shunt devices which are interfaced with the bulk power system through injection buses. Controlling the angle of these buses can effectively damp low frequen...
