As the penetration of renewable energy sources (RES) increases, variation of system impedance seen from grid-connected converters becomes much larger than expected. In this situation, stable operation of converter becomes more challenging. One of the issues caused by system impedance is resonance harmonic problem. Typically active damping control is used and designed based on the known conditions...
Distributed generation based on emerging energy technologies has become an attractive alternative to the conventional centralized power stations, and has drawn much interest due to the increasing demand of premium electric power. The microgrid is a great example of integrating distributed energy resources through power electronics interface converters for grid-connected or islanding operation. This...
