Abstract

In this paper, a Hierarchical Control (HC) strategy is proposed, which integrates different types of power converters that internally possess the space vector modulation (SVM) technique. The proposed HC is a two-level distributed control type. The first level is composed of internal control that regulates the current and voltage amplitude at the output of the converter and a droop control in charge of sharing active and reactive power between the converters connected to the MG. The secondary control corrects the deviations produced by the primary control, maintaining the nominal values within the parameters established in the network configuration. Finally, connection/disconnection scenarios of converters and loads during the operation of the MG are presented, in this way it is possible to know the performance of the implemented HC, in addition, the structure of the developed MG allows the integration of different types of converters in a scalable way.
