wide-area monitoring
Research activities in the group are focused onthe development of control and protection algorithms and applications, and performing systemanalysis considering the challenges in modernand future power systems.Key research areas: power system real-time control protection and analysis based on wide-areainformation with respect to HVDC and FACTScontrol, wind power integration, power qualityand load modelling. Emphasis is on modern power systems where the level of generation throughconverters is increasing and consequently thelevel of system inertia is decreasing.Other research activities are concentrated on thedevelopment and assessment of power qualitymitigation methods in transmission and distribution systems considering the availability ofmodern compensation devices and wide-areainformation.
