Robust Control for Inter-area Oscillations
In order to reduce the detrimental effects of inter-area oscillations on system stability, it is possible to use Linear Matrix Inequalities (LMIs) to design a multi-objective state feedback. The LMI optimization finds a control law that stabilizes several contingencies simultaneously using a …

Coordinated Control of Inter-area Oscillations using SMA and LMI
The traditional approach to damp inter-area oscillations is through the installation of Power System Stabilizers (PSSs) which provide damping control action through excitation control systems of the generating units. However, study of recent blackouts has shown that the control action provided by a …

A Centralized Wide Area Control of FACTS for Damping Power System Inter-Area Oscillations
… Systems (FACTS) control for damping power system inter-area oscillations is a topic of much interest. However, local decentralized FACTS controllers are either too complicated to be realizable or do not offer satisfactory performance under various system operating conditions. This research …

Improving inter-area oscillations damping of power systems through cooperative active power control of distributed energy resources
The remarkable growth of power electronics-interfaced renewable generations in the electric power grid has the potential to pronounce the effect of frequency disturbances such as inter-area oscillations. These low-frequency disturbances reduce transmission lines capacity, and at worst even damage …

INTERAREA OSCILLATION DAMPING BY USING A PERMANENT MAGNET SYNCHRONOUS GENERATOR WIND TURBINE
… wind turbine control for damping power system inter-area oscillations is a topic of much interest. However, the PMSG wind turbine controls in the generator and grid sides such as a PMSG speed control or dc voltage control do not have a sufficient power modulate to damp the inter-area …

Inter-area oscillation damping in large scale power systems with unified power flow controllers
"Power system oscillations occur in power networks as a result of contingencies such as faults or sudden changes in load or generation. They are detrimental to the operation of the system since they affect system stability and the optimal power flow through it. These oscillations do not usually …

Inter-Area Oscillation Damping with Power System Stabilizers and Synchronized Phasor Measurements
Low frequency oscillations are detrimental to the goals of maximum power transfer and optimal power system security. A contemporary solution to this problem is the addition of power system stabilizers to the automatic voltage regulators on the generators in the power system. The damping provided by …

DYNAMIC ENHANCEMENT OF THE FUTURE SASKPOWER INTERCONNECTED NORTH AND SOUTH SYSTEMS: THE HVDC INTERCONNECTION
… the South system. Recently there has been an interest in connecting the two systems to improve the security, stability and reliability of the integrated system. Grid interconnections, however, especially between weak and strong systems, often result in the arising of low-frequency oscillations …

Distributed Energy Dynamics Control for Stable Power Electronic-Enabled Electric Power Systems
… principles of energy conservation and system interconnection. It extends the previously introduced second-order energy dynamics model by relaxing the assumption that energy in tangent space can be treated as an independent disturbance. The resulting contribution is a third-order model that …

Evaluation of Stability Boundaries in Power Systems
… movements evaluated here address the effects of inter-area oscillations on the system which occur in the seconds to minutes time period. The first uses gain scheduling techniques through creation of a set of linear parameter varying (LPV) systems for many operating points of the non-linear …

Propagation of Electromechanical Disturbances across Large Interconnected Power Systems and Extraction of Associated Modal Content from Measurement Data
… disturbances propagate throughout the system area with finite speed. This propagation takes the form of a traveling wave whose arrival time at a particular point in the system can be observed using a wide-area measurement system (WAMS). Observations of these waves both through simulation and …
