Abstract: This paper reviews aspects of stability in microgrids. As there are different applications of microgrids, the aspect of stability also varies. This paper reviews and analyses small signal and large signal stabilities, besides dwelling on the different aspects involved in the stability of microgrids. The small and large signals of different types of microgrids are reviewed, alongside the transients and the stability of output voltage. Large signal analysis of generators and individual loads are also encompassed in this paper. This paper also sums up the scope for future research in stabilities of both large and small signals. In addition to this, the methods to improve signal stability is also covered in this paper.
Keywords: Microgrid, Small-Signal, Large-Signal, Lyapunov Method, Eigenvalue Method.
