Reformulating dq Impedance Matrices via Pauli Decomposition for Root-Cause Analysis of Instabilities in Grid-Connected Converters
Josue Andino, Milan Prodanovic, Javier Roldan-Perez
The increasing penetration of converter-interfaced generators in power systems has led to the adoption of impedance-based criteria as an alternative framework for assessing and ens…
Equivalent modelling for the fundamental frequency dynamic variation: State-space, impedance, and power-frequency representations
Pablo Rodriguez-Ortega, Dionysios Moutevelis, Javier Roldan-Perez +1
Stability of power electronic converters connected to power grids is commonly assessed by using the impedance criterion while the stability of power grids is typically analysed by…
Network-Reconfiguration-Aware Power Oscillation Damping Controller for Newly Commissioned Converter-Interfaced Power Plants
Njegos Jankovic, Javier Roldan-Perez, Milan Prodanovic +3
In recent years, transmission system operators have started requesting converter-interfaced generators (CIGs) to participate in grid services such as power oscillation damping (POD…
Centralised Multimode Power Oscillation Damping Controller for Photovoltaic Plants with Communication Delay Compensation
Njegos Jankovic, Javier Roldan-Perez, Milan Prodanovic +1
Low-frequency oscillations are an inherent phenomena in transmission networks and renewable energy plants should be configured to damp them. Commonly, a centralised controller is u…
