Comparison between Voltage Oriented Control and Synchronous Power Control for Grid-Connected Inverter Applications

With the rising of renewable power generation, there are new challenges to be addressed in order to maintain the electrical system operation stability. So, in literature, new grid-connected inverter control techniques have been studied. This paper focuses on a comparison between a grid-following control technique, called Voltage Oriented Control and a grid-forming control technique, called Synchronous Power Control, to underline the advantages offered by the latter. Through a simulation analysis in Matlab/Simulink environment, the benefits and drawbacks of these control approaches have been analyzed and discussed.
