“…The above-cited works present useful formulae that could be integrated in the IEC 61660 approach when DC distribution systems are applied to microgrids operating in island mode. Reference [13] presents an algebraic model to approximate the DC short-circuit current contribution of converters without DC fault ride-through capability. In [14], the authors analyze the limits in the application of the IEC 61660 standard to HVDC systems.…”

In this paper, the issues related to short-circuit calculations in hybrid AC/DC microgrids are discussed. The reference standard for short-current calculations in DC systems is the IEC 61660, which provides a mathematical formulation of the problem. The standard only includes radial DC grids and does not consider a more complex system, such as meshed DC systems or a hybrid AC/DC microgrid. This paper proposes a generalized approach that can be used independently of the characteristics of the hybrid system. The proposed approach is applied to four test microgrids with different distributed sources and number of nodes and the results are compared with those obtained simulating the same grids with Neplan 360 ® .
