The capacity of installed converter-based distributed generators (DGs) and renewable energy sources (RESs) over the world is rapidly growing; and this increases the significance of grid-connected converters (GCCs) that interface the primary power sources to the grid. It is well known that the quality of control and functions of these power converters in different operation modes significantly affects the grid dynamic performance. Moreover, the increasing penetration of converter-interfaced RESs and the control flexibility of GCCs motivate the use of these converters to develop additional ancillary services to control undesired system dynamics in the power grids. Moreover, appropriate control of GCCs has the potential to offset the intermittent nature of distributed energy resources and provide control support to the host utility during abnormal conditions. To this end, in the present speech, some new trends in GCCs modeling, control, and new functionalities in the visualization of virtual dynamics will be discussed.
