摘要

Self-governing microgrids may consist of several conventional synchronous generators, converter-based distributed resources, and energy storages. In this paper, an eigenvalue-oriented stability assessment method is established to study the small signal stability of such systems that have complex dynamic characteristics. A new index referred to as the microgrid's marginal frequency stability index is established. This index is then used to determine the influence and correlation between sizes, quantities and internal parameters of the resources and loads on the microgrid's stability. Likewise, using this index, the impact of the isolation and coupling impedance amongst resources and loads are studied on the microgrid's stability. The findings of this study can be employed when designing microgrids to realize more stable systems.
