This paper presents stability analysis of a distributed generation (DG) controller, in an islanded mode, based on the Mapping Theorem and the Zero Exclusion Condition, and validates the results based on a laboratory scale experimental setup. The DG unit is ...
This paper presents a Discrete-time Model Predictive-based Control strategy for the voltage regulation of an islanded distributed generation (DG) unit. The DG unit includes a voltage source converter (VSC) interfaced to the grid through a switch and a coup ...

Increasing concerns regarding global warming caused by greenhouse gases, which are mainly generated by conventional energy resources, e.g., fossil fuels, have created significant interest for the research and development in the field of renewable energies. ...
This paper proposes a cascade or multiloop digital control strategy for the voltage regulation of a three-phase islanded single distributed generation (DG) unit microgrid and its dedicated load. The cascade control strategy consists of an inner dq-currents ...
Modern trains with active line-side converters are currently the state-of-the-art technology in the traction industry. In such systems, the active line-side converter of the drive system can be exploited for power quality improvement purposes. In this pape ...
This paper presents an alternative way for the current regulation of single-phase voltage-source dc-ac converters in direct-quadrature (dq) synchronous reference frames. In a dq reference frame, ac (time varying) quantities appear as dc (time invariant) on ...
