Control of converter interfaced generation

Abstract

The chapter presented an overview of implementation options for grid connected converters. The evolution of the presented solutions also represent how the role of power electronic converters has been evolving over the years. The grid-following concept can be seen as the first stage of an ongoing development, in which the role of renewable power generation was initially considered marginal in the power system context. In the recent years, correspondingly with the growing penetration of wind and solar installations, the attention has been moved toward grid-forming approaches because of their capability to play a key role in grid dynamics. Solutions like VSM can be seen as a sort of continuity with the past but reinterpreted with the programmability of power electronics. The control freedom provided by power electronics is now offering the possibility to consider also completely new approaches that are intended for a fully electronic grid. The VOC is one example in this direction which, by exploiting non-linear dynamics, offers a new and more robust way to work in grids without significant physical inertia from rotating machines.
