Traditional power systems have been gradually shifting to power-electronic-based ones, with more electronic devices (including converters) incorporated recently. Faced much complicated dynamics, it is a great challenge uncover its physical mechanisms for system stability and/or instability (oscillation). In this paper, we first establish nonlinear model of multi-converter within the DC-link vol...

Microgrid stability issues are classified into three categories: transient, voltage, and small signal (SSS). Small variations in the load demand perturbations control system line impedance parameters can cause instability, which be avoided by performing an SSS analysis. This paper focuses on investigating impact of passive filter a MG grid-connected mode. Therefore, was represented mathematical...
