Stability Analysis of Three-Phase AC Power Systems Based on Measured D-Q Frame Impedances
… is of great concern for distributed power systems with a large number of regulated power converters. These converters are constant-power loads (CPLs) exhibit a negative incremental input resistance within the output voltage regulation bandwidth. In the case of dc systems, design …

Applications of Power Electronic Converter Based Wideband System Identification in Grid Tied AC Power Systems
… However, if this information is fed back into the controller as a slower outer control loop, it can be used to recalibrate control parameters on the fly. This allows the control to maximize performance over a wide range of operating conditions. The purpose of this work is twofold: to …

An Algorithm and System for Measuring Impedance in D-Q Coordinates
… conducted at the Center for Power Electronics Systems (CPES) at Virginia Polytechnic Institute and State University. Chapter 1 introduces the concept of impedance measurement, and discusses previous work on this topic. This chapter also addresses issues associated with impedance measurement. …
