As decarbonized power systems are mainly based on power electronic converters, the operational behavior of electrical power systems will be more and more determined by the control concepts of these converters. The wide variety of control concepts developed over the last years, however, often causes ambiguity and misunderstanding among power system experts regarding the performance of converters and converter-dominated power systems. Reviewing papers and classification schemes for converter control exist in great numbers but they do not cover the full range of control concepts or only deal with specific applications like microgrids. Therefore, this paper proposes an advanced classification that brings together different existing classification schemes, control concepts and control features and shows their interrelations in a new and comprehensive way. The proposed classification scheme combines four different criteria: the steady state equivalent circuit of the converter, the operating characteristic (grid-following, grid-forming, grid-supporting), different control modes (and submodes) regarding power, voltage and frequency and the ability/necessity to operate grid-connected. The control modes also include control features like virtual inertia or virtual impedances. Based on a double synchronous reference frame converter model, the different control concepts were presented by means of their control loops and equivalent circuits. The comparison with existing classification schemes and the application to different control concepts found in literature showed that the proposed classification scheme does not only provide a more detailed (submode-based) converter control classification but it also revealed new control concepts that were verified by simulation and experimental results. Thus, the control concepts for power electronic converters were reclassified, restructured and extended. In this way, the classification scheme proposed in this paper creates a proper basis for a comprehensive understanding of converters and converter-dominated power systems.
