Abstract :
This paper introduces a state-space controller for grid current control which has been developed to optimize the system behaviour of grid connected inverters during voltage dips and short circuits. The performed tests illustrate that in comparison to standard PID-controllers a considerable improvement of the system performance could be realized.
