Impedance-based method has been increasingly adopted to assess the stability of inverter-based resources (IBRs). To get a better view of the state-of-the-art and challenges for implementing the impedance-based dynamic analysis, a survey with general/specific questions has been initiated by IEEE Task Force on Frequency-Domain Modeling and Dynamic Analysis of High-Voltage Direct … [Read more...] about A Survey on Impedance-Based Dynamics Analysis Method for Inverter-Based Resources

Assessing SMPS Voltage Regulator Dynamics From Output Impedance
Stable operation of a SMPS (switching voltage power supply) hinges on action within the feedback control and compensation network. The way in which the regulator performs is also influenced by the nature of filters attached on either side of it between the source and load. This article shows how stability can be assessed using only knowledge of the system’s output impedance. … [Read more...] about Assessing SMPS Voltage Regulator Dynamics From Output Impedance
