Microgrids have the potential to provide customers with improved power quality and reliability. However, there are technical challenges related to the operation and control of microgrids and the distributed energy source (DERs) that constitute them. Resonance caused by the low-pass filters connected to the voltage source inverters of the DERs is one of those issues in the operation of microgrids. This paper proposes a novel technique of Active Damping Algorithm (ADA) for resonance damping and improving the dynamic stability of a microgrid composed of multiple converter-interfaced DERs. The paper considers two cases; one is where the resistor and the filter capacitor are connected in parallel, and the other is where they are connected in series. The proposed active damping method is based on output current feedback with automatically calculated and adjusted damping coefficients to suppress resonance. The proposed method was verified through simulation and experimental tests carried out using PSCAD/EMTDS and an operational microgrid in Beijing, China. The results from both the experiment and simulation analysis showed that the devised method was able to achieve the intended target; where the filter resonance is effectively surpassed and the voltage and frequency dynamic responses are quite stable and within the acceptable range during large power changes in the microgrid system.
