Abstract

Power-grid connected voltage-source converters provide two-way energy exchange with the grid. They are used for renewable energy applications, combined heat and power, active filtering and loads with dynamically changing working conditions. Aggravated grid codes and dynamic loads require very fast control methods. A control based on the integral of the grid voltage (called grid flux) offers extremely fast dynamics and graphical understanding.
