Abstract

According to the requirements of reliability analysis of different AC/DC hybrid microgrid grids, this paper proposes an analysis method based on flexible reliability index. Firstly, two kinds of universal low voltage AC/DC hybrid microgrid grid structure schemes are proposed; Secondly, the matrix model of microgrid topology is established; Then the flexible reliability index of microgrid is proposed; Finally, by comparing and analyzing the impact of different component failures on the system reliability of a real microgrid under different grid structures, it is verified that the proposed method can comprehensively and accurately reflect the reliability of the microgrid, and has high flexibility and scalability.
