| Abstract |
Grid code compliance conditioning of renewable power sources can effectively be countered by modern power electronics. Conventional power electronics have their merits, e.g. lower losses, but fall short when it comes to active grid support during voltage dips due to power system faults. Focus is attended to self-commutated, modular IGBT-inverters which have been applied for control ranges up to 40 Mvar (20 Mvar). If these 4-quadrant IGBT-inverters are equipped with batteries in the DC-link, they also can be applied to counter effects caused by real power. |
