摘要: This paper deals stabilizing method of the interaction problems among interconnected power electronics based devices in a distribution system. Even if each inverters network is stable individually, combined stability cannot be assured unless holistic assessment performed. The impedance criterion used to study effect active damping on system stability. A benchmark Cigre modeled under and validated using PSCAD/EMTDC simulation. result shows that not all need have for but some can effectively change network, thus overall becomes stable.
