Distributed wide-area control of power system oscillations under communication and actuation constraints

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

Monitoring and Control of Power System Oscillations using FACTS/HVDC and Wide-area Phasor Measurements

Power oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective...

Wide Area Coordinated Control of Multi-FACTS Devices to Damp Power System Oscillations

Aiming at damping the inter-area oscillations of power systems, the present study proposes a wide-area decentralized coordinated control framework, where the upper-level controller is designed to coordinate the lower-level multiple FACTS devices. Based on the polytopic differential inclusion method, the derived controller adopts a decentralized structure and it is guaranteed to be robust to mee...

Wide-area Monitoring and Control for Power System Grid Security

Probably the most significant development in the future is the evolution of the EMS to a more intelligent, automated system to analyze, predict and prevent events leading to a total system collapse. The transition to a highly automated system is possible in part by the recent advances in communication technology, hardware architecture, web services and installation of synchronized phasor measur...

Power Differential based Wide Area Protection

Current differential based wide area protection (WAP) has recently been proposed as a technique to increase the reliability of protection systems. It increases system stability and can prevent large contingencies such as cascading outages and blackouts. This paper describes how power differential protection (PDP) can be used within a WAP and shows that the algorithm operates correctly for a...
