Abstract

Clustering of stand-alone microgrids (μgrids) provides advantages in terms of cost efficiency and security of supply. Exemplary island μgrids comprising diesel-based generators were modelled and validated to perform small-signal stability analyses at different operating points as well as in island and cluster mode. According to the results, the occurring modes have much higher frequencies (up to 10 Hz) compared to those in transmission systems. All significant eigenvalues can be classified as controller type and no inter-area eigenvalues are noticed. The clustering of the analysed μgrids does not have a negative impact on the small-signal stability. Further, it can be concluded that a less damping ratio (e.g. 1-2 %) – due to very small damping time constants – is not critical in μgrids.
