Wide-area power oscillation damping control in Nordic equivalent system

Wide-Area Power Oscillation Damping Control (POD) in Nordic Equivalent System

A study is presented on power oscillation damping control (POD) using wide area measurements applied to a single static var compensator (SVC). An equivalent power system model representing key characteristics of the Nordic power system is used. Feedback signals from remote phasor measurment units (PMUs) in Norway and Finland are used to damp the critical inter-area modes through a large SVC uni...

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 (...

Wide-Area Robust H2/H∞ Control with Pole Placement for Damping Inter-Area Oscillation of Power System

The damping of inter-area oscillations is an important problem in electric power systems (Klein et al., 1991; Kundur, 1994; Rogers, 2000). Especially in China, the practices of nationwide interconnection and ultra high voltage (UHV) transmission are carrying on and under broad researches (Zhou et al., 2010), bulk power will be transferred through very long distance in near future from the viewp...

Damping of Inter-Area Low Frequency Oscillation Using an Adaptive Wide-Area Damping Controller

This paper presents an adaptive wide-area damping controller (WADC) based on generalized predictive control (GPC) and model identification for damping the inter-area low frequency oscillations in large-scale inter-connected power system. A recursive least-squares algorithm (RLSA) with a varying forgetting factor is applied to identify online the reduced-order linearlized model which contains do...
